Adding Own Data to Flex Viewer

NeilMillward — Wed, 20 Oct 2010 22:49:52 GMT

I am trying to add an operational layer of points to the flex viewer. I have added the layer in the config.xml file and I don't get any error messages when the viewer loads, I just don't see any of the points on the map.

I have checked the url to the service and this is working.

My points are in State Plane Projection and the base layers are Web Mercator. Could this be the problem?

Thanks

As long as your MapService is not tiled, then it should work fine with your point data being in a different projection than the base layers. What does your <layer> tag look like?

Can you paste your code?

It could be that the type is wrong I was using type="feature" and it needed to be type="dynamic"

But without seeing what you have, it's hard to tell.

It is a dynamic map service. I also added it to the map switcher to see if it worked there and it does.
When I select the CLTies button I am able to see the points but when the Streets button is selected and I check the Centerline Ties box under the "more" button the points do not appear. See code below:

       <basemaps>

            <layer label="Streets" type="tiled" visible="true" alpha="1"
                        url="http://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer"/>
            <layer label="Aerial" type="tiled" visible="false" alpha="1"
                        url="http://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer"/>
            <layer label="Topo"    type="tiled" visible="false" alpha="1"
                        url="http://server.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer"/>
            <layer label="CL Ties"    type="dynamic" visible="false" alpha="1"
                        url="http://gis.cityoforange.org/ArcGIS/rest/services/clTie_index/MapServer"/>
        </basemaps>
        <operationallayers>
            <layer label="Boundaries and Places" type="tiled" visible="false"
                   url="http://server.arcgisonline.com/ArcGIS/rest/services/Reference/World_Boundaries_and_Places_Alternate/MapServer"/>
            <layer label="Fires" type="feature" visible="false" alpha="1"
                   info="widgets/InfoTemplates/SimpleInfoWinWidget.swf"
                   infoconfig="widgets/InfoTemplates/IWT_Fires.xml"
                   url="http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Fire/Sheep/FeatureServer/0"/>
            <layer label="Centerline Ties" type="feature" visible="true" alpha="1"
                   info="widgets/InfoTemplates/SimpleInfoWinWidget.swf"
                   infoconfig="widgets/InfoTemplates/Centerline_Ties.xml"
                   url="http://gis.cityoforange.org/ArcGIS/rest/services/clTie_index/MapServer"/>

        </operationallayers>

Also, when I view the points in the map switcher I cannot get an info window to appear. I created a file named IWT_Centerline_Ties.xml in the InfoTemplates folder.

<?xml version="1.0" ?>
<configuration>
    <fields>CT_NUM,LOCATION,WEBSITE</fields>
    <titlefield>NUM</titlefield>
    <linkfield>WEBSITE</linkfield>
    <datefields></datefields> 
    <zoomscale>24000</zoomscale>
</configuration>

Thanks for your help.

For type "feature", the url should be to the layer in the service you want to use. Try setting the url to http://gis.cityoforange.org/ArcGIS/rest/services/clTie_index/MapServer/0

Thanks,

I have the point layer showing in the viewer but the info window still does not work.

Any help is appreciated.

Nothing happens when you click the black circles? I tried the config from above with the change to the url and it seems to be working for me.

Re: Adding Own Data to Flex Viewer

NeilMillward — Thu, 21 Oct 2010 20:51:36 GMT

No, nothing happens when I click the black dots.

Are you using version 2.1? Do you get any errors when you start the app?

Re: Adding Own Data to Flex Viewer

NeilMillward — Thu, 21 Oct 2010 21:29:44 GMT

Yes I am using 2.1 and there are no errors when I run it in either Firefox or IE.

I am still unable to get the info window to work. I can get a window to pop up when I use the search wiget but just clicking on the point does nothing.

I have noticed in the other operational layers that come with the viewer that the url references a FeatureServer whereas mine references a MapServer.

Could this be the problem and if so what is the difference between FeatureServer and MapServer?

When I publish my mxd it seems that the only choice I have is a MapServer.

I believe that you should set the type in the operational layers to dynamic. It is only a feature if you have set the layer to be editable, I believe. If you put it to dynamic, then do not put the /0 at the end as was suggested earlier.

Re: Adding Own Data to Flex Viewer

Hi Mike,

Tried your suggestion but the popup did not work. I was able to get it to work using the following code:

<layer label="Centerline Ties" type="Feature" visible="true" alpha="1"
                   info="widgets/InfoTemplates/SimpleInfoWinWidget.swf"
                   infoconfig="widgets/InfoTemplates/IWT_Centerline_Ties.xml"
                   url="http://gis.cityoforange.org/ArcGIS/rest/services/clTiePoints/MapServer/0"/>

The problem I have now is that in doing it this way loses the symbology that I had set in the mxd that was published. The other thing I needed in the popup is a link to a pdf document but this doesn't seem to work either.

I am new to this and appriciate any help.

Thanks

RobertScheitlin__GISP — Tue, 26 Oct 2010 01:05:17 GMT

Neil,

The issue with the symbology not coming across is a limitation of not have the data coming from a ArcGIS 10 Server. If you are still using a 9.3.1 server than you will have to provide your own renderer info
here is a sample that demos that http://help.arcgis.com/en/webapi/flex/samples/index.html?sample=Renderer. for the pdf link you will need a

<linkfield>your_pdf_complete_url_ field</linkfield>

in your /IWT_Centerline_Ties.xml file.

Hi Robert,

Thanks for the help.

In regard to the pdf documents, each point has a different document. I have a field named WEBSITE that contains the complete url to the document. eg: http://gis.cityoforange.org/GISData/Images/Centerline_Ties/CT-0239_MapleGrand.pdf

I am able to see this url in the popup but it is not clickable. Below is my IWT_Centerline_Ties.xml code.

<?xml version="1.0" ?>
<configuration>
    <fields>CT_NUM,LOCATION,WEBSITE</fields>
    <titlefield>CT_NUM</titlefield>
    <linkfield>WEBSITE</linkfield>
    <datefields></datefields> 
    <zoomscale>25000</zoomscale>
</configuration>

Thanks.

Neil,

Looking at the code for the SimpleInfoWidget, there is a comment in it

TODO: Add support for link fields

So the bottom line is it won't work with the SimpleInfoWidget.

try switching to the widgets/InfoTemplates/InfoPopupWidget.swf

Re: Adding Own Data to Flex Viewer

NeilMillward — Wed, 27 Oct 2010 15:37:15 GMT

Robert,

I made the following change from SimpleInfoWinWiget in the config.xml file as you suggested.

           <layer label="Centerline Ties" type="Feature" visible="true" alpha="1"
                   info="widgets/InfoTemplates/InfoPopupWidget.swf"
                   infoconfig="widgets/InfoTemplates/IWT_Centerline_Ties.xml"
                   url="http://gis.cityoforange.org/ArcGIS/rest/services/clTiePoints/MapServer/0"/>

After making this change and clicking on the point I don't get any response.

Thanks.

Neil,

OK studying the code tells me that won't work either as you figured out. So I guess hyperlinks are a no go until they get that finished in the SimpleInfoWidget.

Re: Adding Own Data to Flex Viewer

NeilMillward — Wed, 27 Oct 2010 17:05:34 GMT

Robert,

Thanks for your help.

You would think that to be able to link to a document or webpage from a field in the data would be a basic need when using the popup window.
