MapManager bug related to sublayers and feature layers about arcgis-viewer-flex

[jcfranco]

Could you provide a sample config to reproduce the issue?

[carterbancroft]

Thanks for the fast response. In pulling it out to the simplest case, I learned that it will work with a feature layer alone, but a feature layer with the deprecated infoconfig for a popup will cause the error. So you'll need to add a basic old school info popup along with this config. I've included all the code necessary.

A simple config that will cause the error...

<?xml version="1.0" ?>
<configuration>
    <title>ArcGIS Viewer for Flex</title>
    <subtitle>a configurable web mapping application</subtitle>
    <logo>assets/images/logo.png</logo>
    <style>
        <colors>0xFFFFFF,0x333333,0x101010,0x000000,0xFFD700</colors>
        <alpha>0.8</alpha>
    </style>

    <geometryservice url="http://tasks.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer" />

    <widget left="10"  top="50"    config="widgets/Navigation/NavigationWidget.xml" url="widgets/Navigation/NavigationWidget.swf"/>
    <widget right="-2" bottom="-2" config="widgets/OverviewMap/OverviewMapWidget.xml" url="widgets/OverviewMap/OverviewMapWidget.swf"/>
    <widget right="20" top="55"    config="widgets/MapSwitcher/MapSwitcherWidget.xml" url="widgets/MapSwitcher/MapSwitcherWidget.swf"/>
    <widget left="0"   top="0"     config="widgets/HeaderController/HeaderControllerWidget.xml" url="widgets/HeaderController/HeaderControllerWidget.swf"/>

    <map wraparound180="true" initialextent="-14083000 3139000 -10879000 5458000" fullextent="-20000000 -20000000 20000000 20000000" top="40" addarcgisbasemaps="true">
        <operationallayers>
            <layer label="Demographics" type="dynamic" visible="true" alpha="1.0" url="http://server.arcgisonline.com/ArcGIS/rest/services/Demographics/USA_Median_Household_Income/MapServer">
                <sublayer id="1" popupconfig="popups/PopUp_Demographics_BlockGroups.xml"/>
            </layer>
            <layer label="Test" type="feature" visible="true" url="http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Demographics/ESRI_Census_USA/MapServer/5"
            infoconfig="widgets/test/test.xml"
            info="widgets/test/TestWidget.swf" /> 
        </operationallayers>
    </map>

    <widgetcontainer layout="float">

    </widgetcontainer>
</configuration>

Then create a new widget in src\widgets\test\ with a blank test.xml file. TestWidget.mxml's code is as follows...

<?xml version="1.0" encoding="utf-8"?>
<viewer:BaseWidget xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:viewer="com.esri.viewer.*" implements="com.esri.viewer.IInfowindowTemplate">
    <fx:Script>
        <![CDATA[
                public function set infoConfig(value:XML):void
        {
            configXML = value;
        }

        private var _infoClass:Class = TestWidget;
        public function set infoClass(value:Class):void
        {
            _infoClass = value;
        }

        public function get infoClass():Class
        {
            return _infoClass;
        }
    ]]>
</fx:Script>
</viewer:BaseWidget>

Just wanted to see if in fact someone over there was able to replicate my issue at least.

For what it's worth, I realize the infoconfig popup is deprecated. However, my understanding is that it should continue to work along with the new style popups, correct? The main reason I can't use the new ones in all cases is because as best as I can tell there is little to no ability to customize the popup for the new xml configured popups outside of what can be modified in the xml. I'd just use the old info win ones in all cases if I could too, but as far as I can tell the old style ones cannot be used on sublayers.

[jcfranco]

Sorry for the belated response.

I managed to reproduce the issue using your sample, so I'll look into this and will follow up soon as I can.

Thanks.

[carterbancroft]

Most appreciated. I just wanted to make sure I'm not crazy. For now it seems like I'm able to work around it by rearranging my web config.

Edit: Scratch that... For my data, there doesn't appear to be a way to organize the config in such a way that all the required operational layers can be listed and not get the error. The config gets a bit fragile once you have feature layers with the old school infowin popups and sublayers.

You can customize the PopUpRendererSkin that comes from the API.

[carterbancroft]

Interesting, thanks Dasa. I'd have to look into it a little more to make sure it'd work, different popups would need to use different PopUpRendererSkins, it couldn't be the same skin project wide.

For example, I have one set of point features that need to have a popup with some extra buttons, one of which opens a new flex window with more detailed information. Then there is another set of point features that need to open a popup, but at the same time need to launch a new browser window to a link tied to the selected point feature.

[dasa]

You can extend PopUpRenderer to create a new class that you can then create a separate css type selector on.

[carterbancroft]

Thanks, that makes sense. In any case I don't, at the moment, have time to switch our old code to a model like that.

[jcfranco]

I've pushed a fix that adds the layers in the proper order: https://github.com/rscheitlin/arcgis-viewer-flex/commit/0940779614f04509e02cacbec919e0437c7e51d8

[carterbancroft]

Awesome, that fixes the issue. Thanks so much! I can close the issue or let someone on your end do it in case there is anything more that needs to be done.

[rscheitlin]

JC, The link you provided to the fix no longer works can you provide an updated link? Robert

[jcfranco]

I've updated the link to point your repository since we dropped the branch after 3.1 was released.
