using PopUpInfo for a layer with dynamic join

xiaowenyang — Mon, 04 Mar 2013 20:42:34 GMT

I've added a layer with dynamic join -- very similiar to (http://resources.arcgis.com/en/help/flex-api/samples/index.html#/DynamicLayerInfo_JoinDataSource/01nq00000088000000/). However, when I try to use PopUpInfo to show the field value, even though I tried different combination of layername.fieldname or fieldname, I still got no luck. Can anyone guide me this?

Thank you in advance.

Xiaowen,

You will need to supply a little more info for people to trouble shoot, like your popup config and either a screen shot of your rest URL or a link to the rest endpoint if it is public.

One thing to remember is that flex is case sensitive

Hi Anthony,
Thank you for your reply. Here's my set up
My spatial table is
http://23.21.106.101:6080/arcgis/rest/services/AdminBoundary/MapServer
This table is linked to another table by code, the join relationship is very similar to below

{"source": {
"dataSource": {
"workspaceId": "MyPostgreSQL",
"dataSourceName": "user1362603115943",
"type": "table"
},
"type": "dataLayer"
}}

So, I can add a layer like (http://23.21.106.101:6080/arcgis/rest/services/AdminBoundary/MapServer/dynamicLayer?layer=%7B%22source%22%3A+%7B%0D%0A+%22dataSource%22%3A+%7B%0D%0A++%22workspaceId%22%3A+%22MyPostgreSQL%22%2C%0D%0A++%22dataSourceName%22%3A+%22user1362603115943%22%2C%0D%0A++%22type%22%3A+%22table%22%0D%0A+%7D%2C%0D%0A+%22type%22%3A+%22dataLayer%22%0D%0A%7D%7D+&f=html) into my application by program. Then I want to add popup info for this new created layer by the mudal below. However, even though this code works for other regular(no dynamic join layer), I can not make it work for this dynamic layer with dynamic join.

private function configurePopUp(indicator:Object, layerID:Number):void{
    /**showing the pop up info for indicator layer*/
    var popUpInfo:PopUpInfo = new PopUpInfo();
    var pFieldInfos:Array = [];
    var pFieldInfo:PopUpFieldInfo = new PopUpFieldInfo();
    //pFieldInfo.fieldName ="sdegdb." + String(indicator.viewName).toLowerCase()+ "." + indicator.fldName;
    //pFieldInfo.fieldName = "newtam6";
    //pFieldInfo.fieldName = String( indicator.viewName).substr(7, (String( indicator.viewName).length-7)) + "." + indicator.fldName;
    pFieldInfo.fieldName = "newtam6";
    pFieldInfos.push(pFieldInfo);
    popUpInfo.title = indicator.indicatorStr;
    popUpInfo.popUpFieldInfos = pFieldInfos;
    //popUpInfo.description = "indicator is {sdegdb." + indicator.viewName+ "." + indicator.fldName+ "}";
    Alert.show("indicator is" + pFieldInfo.fieldName + "     " + layerID.toString());

    var popUpRenderer:ClassFactory = new ClassFactory(PopUpRenderer);
    popUpRenderer.properties = {popUpInfo: popUpInfo };
    var layerInfoWindowRenderer:LayerInfoWindowRenderer= new LayerInfoWindowRenderer();
    layerInfoWindowRenderer.layerId = layerID;
    var infoWindowRenderer:ClassFactory = new ClassFactory(PopUpRenderer);
    infoWindowRenderer.properties = { popUpInfo: popUpInfo };
    var arrLayerInfoWindowRenderer:Array = [];
    arrLayerInfoWindowRenderer.push(popUpRenderer);
    InDynMapLyr.layerInfoWindowRenderers = arrLayerInfoWindowRenderer;
   }

Thank you for your help!

Have you tried:

sdegdb.editor.User1362603115943.newtam6

As your field name

I've tried the following options, none of them works
sdegdb.editor.User1362628252032.newtam6
sdegdb.editor.User1362628252032.max_p_ch14nou1990
max_p_ch14nou1990
User1362628252032.max_p_ch14nou1990

Is there any combination that I missed?

Thanks

What about just dropping the first bit:

editor.User1362603115943.newtam6

Hello Anthony,
I modified the sample mxml code to figure out the issue. Even though <s:Label text = "data: {ObjectUtil.toString(data)}"/>

can successfully display the data, <s:Label text="ID: { data.ancestry.State}"/> won't show anything at all. I am wondering how can I define popupinfo by actionscript to show something like ObjectUtil.toString(data)?

Thanks

I've figured out the question above for showing field info for dynamic join . Here's the code for labledatarender

<fx:Component>
       <esri:LabelDataRenderer label=" Details">
        <s:VGroup paddingBottom="5"
            paddingLeft="5"
            paddingRight="5"
            paddingTop="5" >
         <fx:Script>
          <![CDATA[
           import mx.utils.ObjectUtil;
           [Bindable]
           var fieldName:String = "ancestry.State";
          ]]>
         </fx:Script>
         <s:Label text="ID: { data[fieldName]}"/>
         <s:Label text="Name: {data.states.ASIAN }"/>
         
         
        </s:VGroup>
       </esri:LabelDataRenderer>
      </fx:Component>

With this experience, layer with dynamic join should use customized labeldatarender instead of builtin popupinfo for arcgis viewer for flex. The trick is data[fieldName].
