Adding Operational Layers

JamesArmstrong — Fri, 10 Jun 2011 14:25:53 GMT

ArcGIS 9.3.1
ArcServer 9.3.1
Flexviewer 2.3.1
Status: newbie

I have downloaded the flexviewer and got it running on my ArcServer using the default config.xml file. I have changed the initial extent as well as added a wkid= 2264 (North Carolina) to the intitialextent line. The site seems to work fine.

Then I add my own operational layer (from my server)- and I get an error and the site will not load. If this layer is commeted out, the site again works fine. Spent last few days researching ans trying different things. I have learned alot, but not how to solve this issue. Any suggestion or points in the right direction will be greatly appreciated. Below is the <map> portion of my config file and I have attached the screen shot of the received error. The site is still in test mode and not open to general internet.

James,

Open back up your MXD and unhide the ObjectID and Shape Fields and republish, then clear your REST Cache using the REST Admin site and try again.

Hello,

You also have an error in your <layer> tag shown below in Red, you've self closed the <layer> tag with the <layer /> slash just at the end outside of the quotes for the URL as well as closing with a </layer>. If you remove this / or remove the </layer> tag just below it, it should work.

In XML you have two ways of closing a tag, either self closing with the <tag /> form or the open and close tags <tag> </tag>. It will error if you use both, as the <tag /> will already be closed when attempting to create a closing </tag>.

Thanks for the assist. I was able to add my Parcel Layer to config.xml. Though the re-projecting caused a huge proformance problem, the previous error dissappeared and the layer showed up in the opererational layers list. The only thing is that the data for the parcel layer does not show up. Perhaps it is a symbology issue. Any suggestions will be graciously accepted.

I am new to Flex I am having the same issue. The parcels layer appears in the list, but does not draw. I didn't define the wkid, although my operational layers are in a different projection than the ESRI base map I'm using. Is that a problem? The interesting thing is that I'd gotten the parcels layer to work in the 2.2 version, copied the code over into the 2.3 config.xml, added the popupconfig line, and it no longer worked. Any help is appreciated.

Here is my code:

<map wraparound180="true" initialextent= "-8653000 4862000 -8409000 4978000" fullextent="-8653000 4862000 -8409000 4978000" top="40">>

Hi Megan,

There's a couple things wrong in your config file there. Your popups are not configured correctly. Take a look at the ESRI Viewer Docs but in brief:

Popups are generally configured in a <sublayer> tag, if you are configuring them for a single map feature layer it is possible to do as you have, by including it in the <layer> tag, however it has to be while the layer tag is still open. In your code you've self closed the layer tag by <layer ... /> and then called the popupconfig parameter outside of the closed layer tag. The popup would have to be set before that / .

I believe for dynamic types you must use the sublayer tag, in which case the initial <layer..> must not be self closed, and instead be later closed by a </layer>.

I.E.:

<layer ...>
    <sublayer id="x" popupconfig="popups/example.xml" />
</layer>

In which case

<layer label="Parcels" type="dynamic" visible="false"
url = "http://arcims/ArcGIS/services/testparcels/MapServer"/>
popupconfig="popups/Popup_Parcels.xml"/>

should be:

<layer label="Parcels" type="dynamic" visible="true" url="http://arcims/ArcGIS/services/testparcels/MapServer">
     <sublayer id="x" popupconfig="popups/Popup_Parcels.xml"/>
</layer>

Re: Adding Operational Layers

MeganBirch — Wed, 15 Jun 2011 18:16:19 GMT

Justin,

Thank you for your response. I made the changes you suggested, but the layer still does not appear. I even took out the popupconfig altogether, with no change.

<layer label="Parcels" type="dynamic" visible="false" alpha = "0.5"
                   url = "http://arcims/ArcGIS/services/testparcels/MapServer">
     </layer>

I also tried changing the service type to feature since the service only contains one feature class (and therefore no sublayers), without success:

            <layer label="Parcels" type="feature" visible="false" alpha = "0.5"
                   url = "http://arcims/ArcGIS/services/testparcels/MapServer/FeatureServer">
     </layer>

I'm beginning to think that the problem might be with my service and not my code. But since the following worked in the previous version of the template, I'm not certain about that:

<operationallayers>
    <layer label="Parcels" type="dynamic" visible="true"
     url = "http://arcims/ArcGIS/rest/services/testparcels/MapServer"/>
</operationallayers>

Although, in the previous version, I did notice that in the layers list the Parcels could be expanded, which is not the case in the new version, so something must be different. If you have any other thoughts, I'd appreciate them.

Hi Megan,

Could the highlighted parameter be the issue?

<layer label="Parcels" type="dynamic" visible="false" alpha="0.5"
   url="http://arcims/ArcGIS/services/testparcels/MapServer">
</layer>

Visible must = true for the service to show,

Re: Adding Operational Layers

MeganBirch — Thu, 16 Jun 2011 11:36:34 GMT

According to the help (ArcGIS Viewer for Flex -->Configure the Viewer--> The Layer Tag), visible "Determines whether the layer is visible or not when the application first opens. Boolean value, default is "false"." Regardless, I've tried it both ways with the same result.

You will want to ensure you are pointing to the REST endpoint for your map service in your config.xml file. Right now it looks like the code is referencing:

<layer label="Parcels" type="dynamic" visible="true" alpha="0.5"
url="http://arcims/ArcGIS/services/testparcels/MapServer">
</layer>

When it should be:

<layer label="Parcels" type="dynamic" visible="true" alpha="0.5"
url="http://arcims/ArcGIS/rest/services/testparcels/MapServer">
</layer>

I am haveing the same problem I am running ArcServer 10, ArcGIS 10, Flexviewer 2.3.1, Adobe Flash Builder 4. I downloadeed and did everything the Getting started instructions say to do for the uncompiled version of the viewer I got all my widgets to work but when I add an operational layer it shows up in the more tab of the map switcher but does not display here is my code:

     <operationallayers>
         <layer label="Parcels" type="dynamic" visible="false" alpha="1.0"
                   url="http://gisserver/HHGIS/rest/services/HH_GIS/MapServer/46"/>
     </operationallayers>

After I add code to the flex project I save and build the project then go to run index.mxml and it comes up in a IE window and everything displays except my parcel layer. Any sugestions

Here's my current layer that I'm trying to get setup.

<layer label="CN Jurisdiction" type="dynamic" visible="true"
url="http://geodata.cherokee.org/ArcGIS/rest/services/Maps/CNBoundary/MapServer/0"/>

If you look at the service I can get it to show up as a JavaScript or ArcGIS.com map but can't seem to get it to show up in my flexviewer (http://geodata.cherokee.org/flexviewer). I'm not a programmer but I think I've got it entered right, just not sure where to go from here. Any ideas?

as far as I know, type="dynamic" does not allow you to specifically show a single layer from the map service. try removing /46/. If you want to specficially only show one layer. I think you need to use type="feature"

Here's my current layer that I'm trying to get setup.

<layer label="CN Jurisdiction" type="dynamic" visible="true"
url="http://geodata.cherokee.org/ArcGIS/rest/services/Maps/CNBoundary/MapServer/0"/>

Same with you, try removing the /0

The end of the URL should not have a / in it.

Unfortunately there is no way to exclude layers from a map service, only displaying visible on/off at startup. Use this: visiblelayers="0,1,2,6,7,8,9,10,11,12" where number = id of layer.

A lot of great posts to this thread, thank you. However, I am still having trouble seeing the "parcel" layer on flexviewer. The layer loads and is shown in the TOC. I can turn the layer off ans on, but the data does not show. The layer is saved with a compound symbol, but I checked this off by using another layer with a simple line symbol.

Any ideas as to why I cannot see the daat in the layer I am adding as an operational layer?

You need to add the mode and useamf attributes to your layer element

That worked! I could have swore I tried that before but I've tried so many different things maybe I didn't. Good news is, it works now.

I find that clearing internet cache on the client, flash cache on the client, and rest cache on the server helps. Also, closing the browser down, and then reopen.
simply hitting the refresh button doesn't seem to 'refresh' the map services.

Thanks, but this did not seem to work. I have tried to use other layers in the service as well as change from feature to dynamic (also changing the url as appropriate). the layer shows up in the TOC but no data is shown. I am sure it very basic, but something that I have not yet been able to find. I can not move forward until this is solved, so any suggestion or advice will be appreciated.
