...suggested we just copy the old xml into the new but how do I know what exactly to copy?

I meant copy the whole xml file (not parts of it), thus overwriting the new default one. For example, if you made changes to the config.xml you can copy that file into the new viewer. The same for any widget configuration file (*.xml) that you have customized.

We try to make the viewer backward compatible as much as possible, so this should work for most scenarios (from 2.1 and later). You should also read the "what's new" to see what have changed.

Hope this helps...

I am in the process of migrating my modifications from 2.1 to 2.2, and for every code module and configuration file I wonder if there are any changes at all to the new version. If I knew there were no changes I could just use my previous file, but I'm going through the tedious process of finding all my modifications and editing them into the new files.

At the risk of asking too much, would it be too difficult to put a date and/or version number in each file (.xml, .mxml, .as) so we could save some time with the migration? Or perhaps provide a list of changed or unchanged files (whichever is easier)?

Thanks,
Marc

What I would really like is just a very simple wizard that does the migration similar to a normal software update. Many of us that are using the Flex Viewer are newbies to programming and are not very comfortable constantly making changes to xml files. bjorn suggested we just copy the old xml into the new but how do I know what exactly to copy?

This issue is discussed in following thread

Does the legend widget require Server 10? I checked the FAQ, but it only said time and editing required 10. The widget loads and opens when I click it, but the layer icon with the red X over is the only thing that shows. There really is no config for this widget, so Im not sure what else it could be.

For the sake of discussion, I used a combination of two free programs to migrate from 2.1 to 2.2. I used PathSync to examine the two directories for changes and then 'compare' plugin in Notepad++ to view and update xmls side by side.

The overviewMapWidget doesn't work in this new release because it only displays a blank window

Thanks for reporting the bug. This will be fixed in next release.

Brian,

We'll look at supporting wkid on the layer tag for type "wms" in a future release.

As a work-around, you can try this:

<layer label="NOAA Infrared Satellite"
                type="wms"
                visible="false"
                visiblelayers="RAS_GOES_I4"
                url="http://nowcoast.noaa.gov/wms/com.esri.wms.Esrimap/obs?srs=EPSG:102113"/>

This seems to work but is service dependent. Any additional url parameters are sent by the API in its requests to the servcie. The API will overwrite any it uses, but since it's case-sensitive and it uses SRS, then both srs and SRS will be sent and in this instance, the service seems to look for the srs parameter first.

Hi Dasa,

I tried this, but the service never shows up on the map. My viewer is set up to use the WGS 1984 Web Mercator Auxiliary Sphere projection. What am I missing?

Beyond that, is there any way to set an autorefresh for the WMS, like Dynamic and ArcIMS services? Is there a workaround for this?

Thanks for your help!

The overviewMapWidget doesn't work in this new release because it only displays a blank window (see attached file). However, in previous release it works fine. Any help? You can see at following my overviewMapWidget.xml

<?xml version="1.0" ?>
<configuration>
    
    <initialstate>closed</initialstate>
    
    <layer
            type="tiled"
            mode="dynamic"
            url="http://iderm.imida.es/ArcGIS/rest/services/Vector/Topografico_r_ETRS89/MapServer"/>

</configuration>

After corrupting my map configuration with what I thought was a reasonable "migration path", I had to search for an hour before I found this simple instruction. Could it be included in the "What's New" page next time?

Thanks.

glennhazelton

it seems like it would be nice if the developers on this forum where able to get prior notice of updates to the viewer releases. that way they could publish fresh version of their GREAT samples. at the moment all the samples in the code gallery are set to run on version 2.1. with the download now set by Esri to 2.2 those users like myself who don't have flexbuilder or the knowledge to compile the raw code this out-of-sync state is sort of frustrating.

Hi,

How can I make to work query, search, or something like "identify" but with a wms layer(wms url)?

In config I have:

<basemaps>
<layer
label="axa"
type="wms"
visible="true"
srs="31600"
visiblelayers="axa1"
url="http://localhost:8080/geoserver/wms"/>
</basemaps>
<operationallayers>
<layer label="axa2"
type="wms"
visible="true"
srs="31600"
visiblelayers="axa2"
url="http://localhost:8080/geoserver/wms"/>
</operationallayers>

and in query:

<configuration>
    <layer>http://localhost:8080/geoserver/wms?service=WMS&version=1.1.0&request=GetMap&layers=axa:axa2&srs=EPSG:31600</layer>
    <query>1=1</query>
    <titlefield>Lt</titlefield>
    <linkfield></linkfield>
    <fields all="false">
        <field name="LV" />
        <field name="LV1" />
        <field name="LV2" />
        <field name="AREA" />
    </fields>
    <refreshrate></refreshrate>
    <zoomscale>500000</zoomscale>
    <info>widgets/InfoTemplates/InfoPopupWidget.swf</info>
</configuration>

I know WMS service it's a image format, but also WMS have getFeatureInfo,.... how to use this in arcgis viewer 2.2?

Bjorn and others -
Is there a preferred strategy for copying the 'modified xml's' to the new viewer while leaving enhancements to the new viewer intact? In other words, is there a better/easier way to sync the old and new viewers rather than looking through all of the widgets and comparing code? If I've modified a 2.1 widget, and the widget is improved a 2.2, I don't want to just copy my widget and replace the newer version, I want to merge the two.

thanks

Hi,

Could somebody explain how to integrate the esri geoportal extension widget to this new version (both compiled and source code)? All documentation I've found in forums and webhelp refers to previous versions.

Thanks.

BrianCrumpler

The wkid goes on the map tag, but it may not be needed. Make sure the visiblelayers match the available layer names. You may need to use a tool like HttpFox to see what the request/responses are.

Here's another example using the 2.2 viewer and the WMS feed - one that works and one that doesn't... It does look like this is a projection definition issue...

<layer label="NOAA Infrared Satellite"
type="wms"
visible="false"
visiblelayers="RAS_GOES_I4"
url="http://nowcoast.noaa.gov/wms/com.esri.wms.Esrimap/obs?service=wms"/>

<layer label="Nexrad Radar"
type="wms"
visible="true"
visiblelayers="nexrad-n0r"
url="http://mesonet.agron.iastate.edu/cgi-bin/wms/nexrad/n0r.cgi?"/>

The Iowa State link works but the Nowcoast one doesn't. Iowa State has their service publishing in 102100 but Nowcoast only has the following (http://nowcoast.noaa.gov/help/mapservices.shtml):

SRS Identifier Projection Name
EPSG:4267 North American Datum of 1927 (NAD 27)
EPSG:4269 North American Datum of 1983 (NAD 83)
EPSG:4326 World Geodetic System 1984 (WGS 84)
EPSG:102113 Web Mercator (ESRI Identifier)
EPSG:900913 Web Mercator (Google Identifier)

I have also tried adding in variables for SRS or WKID and they haven't worked, but removing them alltogether makes Iowa State work.

What would be helpful in the next go around would be to have the option to specify the SRS/WKID of the WMS layer since SRS is required by WMS (see http://help.arcgis.com/en/arcims/10.0/mainhelp/mergedprojects/wms_connect/wms_connector/get_map.htm). While it is optimal for the WMS layer to be in the same projection, this is not always possible. This is especially the case when using regional data (ie. national or multi-state like weather) and applying it to local or regional areas where the projections will be different.

Additionally, for cross-jurisdictional interoperability, there is a requirement to be able to leverage multiple projections either automatically or programmatically. Much of your local, regional, federal and multi-state data will be in different projections and the ability to use WMS layers with other ArcGIS server layers should be simple to solve by adding a variable for WKID for the map layer.

If this isn't possible, then while WMS is added, it really doesn't work unless the WMS service provided has an option to output in the same projection as your other map layers which isn't always possible.

Thoughts?

Worked, Thank U; I wrote in config.xml:

<layer
label="axa"
type="wms"
visible="true"
visiblelayers="axa"
url="http://localhost:8080/geoserver/wms"/>

and it's work; Now, it is a way to overlay this data with bing maps, I suppose i have to put to basemap ..bing map and to operationallayers my wms, it will work? and how i do this.

Thank again.

Pedro, about the Print Widget:
The only changes to the Print Widget between 2.2. and 2.1 was related to localization. The actual printing should be the same for both versions.

Maybe the print differences you are seeing is based on the size of your browser at the time of printing. For example, if you're browser is "tall", you will get get a different printout than if you resize to be "wide".

Hi dpaddock,

I made the change in config.xml on basemaps:

<layer
label="axa"
type="wms"
visible="true"
visiblelayers="0,2"
wkid="EPSG:31600"
url="http://localhost:8080/geoserver/wms"/>

and i received a blank page..ESRI logo si loaded and staying on Transferring data from localhost..

i have a crossdomain.xml if help.

Hello. I'm new to Flex. I have been working with Flex Viewer 2.1 for the past couple of months and have changed a lot of the xml files and some of the mxml files as well. What do I need to do in order to migrate to Flex Viewer 2.2 in order to get the updates & fixes and not lose the stuff I've already done?

Thanks!
Cynthia

Hi,

I would like to know if there is a problem with the print widget in that new version. Because of margin cuts the images displayed. Note: That doesn't happen in previous version.

Thanks.

DasaPaddock

The Security error is being thrown because they don't have a crossdomain.xml file on their server. You can either configure the layer to use a proxy or have it skip getting the capabilities.

e.g.

<layer label="Contours" type="wms" visible="true" visiblelayers="hypsography"
url="http://wms.ess-ws.nrcan.gc.ca/wms/toporama_en" skipgetcapabilities="true" version="1.1.1"/>

The skipgetcapabilities and version attributes have been added to the layer tag doc. The WMSLayer uses the map's SpatialRefernce so you can set wkid="900913" on the map tag.

StephenLuzny

Dasa,

Could you elaborate on including a WMS layer in the Operational Layers section of the config.xml file for Flex Viewer 2.2? The documentation does not have much detail.

Specifically, I am attempting to add the hypsography layer from the Toporama Web Map Service (Toporama WMS) of the Earth Sciences Sector (ESS) at Natural Resources Canada (NRCan). See http://geogratis.cgdi.gc.ca/geogratis/en/service/toporama.html for information about this service.

<Layer queryable="0" opaque="0" cascaded="0">
<Name>hypsography</Name>
<Title>Hypsography</Title>
-
<Abstract>
The Hypsography layer represents elevation points and continuous lines formed by peaks of equal altitude used to describe the topography. Elevation of points and lines is always calculated from mean sea level.
</Abstract>
<SRS>EPSG:4269</SRS>

The layer line I have included in my config.xml is as follows:
<layer label="Contours" type="wms" visible="true" visiblelayers="hypsography" url="http://wms.ess-ws.nrcan.gc.ca/wms/toporama_en"/>

Is there an option to set the WMS version in the layer line? An error message I get seems to indicate that FlexViewer defaults to version 1.3.0, but Toporama supports the OGC WMS standard, version 1.1.1.

SecurityError: Error #2048: Security sandbox violation: http://465793h/FlexViewer2.2/index.swf cannot load data from http://wms.ess-ws.nrcan.gc.ca/wms/toporama_en?VERSION=1.3.0&amp;REQUEST=GetCapabilities&amp;SERVICE=WMS.

Additionally, is there a way to specify the EPSG code for the WMS in the layer line? This is not mentioned in the documentation. I suppose that "EPSG:900913 - Google Spheric Mercator", which is supported by Toporama, would match the ArcGIS Online cached services.

DasaPaddock

Here's an example:

<layer
    label="US"
    type="wms"
    visible="true"
    visiblelayers="0,2"
    url="http://sampleserver1.arcgisonline.com/arcgis/services/Specialty/ESRI_StatesCitiesRivers_USA/MapServer/WMSServer"/>

There's more options available. See:

Hi,

Please teach me how to connect to a WMS service or what i have to change in flexviewer-2.2-src to add/work;

Thanks in advance

Next enhancement request:

In the DrawWidget be able to change the measurement font color, weight, size, etc. This is basic needed functionality when dealing with maps with dark backgrounds.

rscheitlin

Bjorn,

That's what I am talking about. I knew you guys were team players.

Keep Up the Good Work.

P.S.

This is probably a REST enhancement request but... I would love the ability to specify the legend image size from the Rest endpoint. I sometimes need bigger swatches when working with picture fill symbols.

BjornSvensson

Robert, thanks for being first to report that no-extent-editing bug.
Chris, this is why you don't see the resize handles for rectangles.

Chris, while there are plans for a more complete print solution with ArcGIS Server, it will probably be released post-2.3.

As for general 2.3 plans, we will be working on the detailed plans next week. We've added an entry to our FAQ called "What about the next version (2.3)?" to share an initial list of some of the items we are considering for the next version.
