Can anyone explain why I get these errors when running a mobile application with the new 3.4 api. Class mx.controls:: DateField could not be found. Class com.esri.ags.skins.fieldClasses::CalendarField could not be found. I can have a completely blank mobile project and add a simple. And these errors come up when running a simulation. Comment out the map portion and they go away. These run errors seem to go away if I switch back to the 3.3 esri api also. I'm not sure if i'm missing something but this usually works right out of the box so I am a bit baffled. Any help would be great thanks.

nav[aria-label="Primary Navigation"] { padding: 0; & ul { list-style: none; width: 100%; display: flex; flex-direction: row; justify-content: start; align-items: start; gap: 30px; padding: 0; & li { margin: 0; } & ul li { list-style: none; } } }

Runtime error with new 3.4 API

I found a solution for 3.4. Instead of changing the PopUpRendererSkin, you need to change the AttributeInspectorSkin. The change is to update it so that it isn't using the CalendarField. Here's an example where I've set it to use a TextField instead. I then saved this to my app's "skins" package/folder.

        <fx:Component id="dateField">             <!--<fieldClasses:CalendarField dateFormat="shortDate" useUTC="false"/>-->             <fieldClasses:TextField minWidth="200"/>         </fx:Component>

You then have to override two styles in a file named "defaults.css" that tells Flex to use your customized AttributeInspectorSkin. The defaults.css file must be in the root of your src folder.

defaults.css:

@namespace esri "http://www.esri.com/2008/ags";  esri|AttributeInspector, esri|RelationshipInspector #attributeInspector {     skinClass: ClassReference("skins.AttributeInspectorSkin"); }

Test app:

<?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"                xmlns:s="library://ns.adobe.com/flex/spark"                xmlns:esri="http://www.esri.com/2008/ags"                applicationDPI="160">      <esri:Map id="map">     </esri:Map>  </s:Application>

You'll need to add a reference to the mx.swc. See:

Thanks for you help Dasa!

I was wondering if I needed to do that but I have not needed to do this with the 3.3 API and I am not using any MX components either. Is the new 3.4 API dependent on the mx.swc?

Also when I do add the mx.swc and the sparkskins.swc like you suggested, simply adding a map component again gives me 5 warnings as shown in the picture. Is there any way to remove these warnings? Again this is a blank project with just a map component added so far.

The other option mentioned at the bottom of that link is to remove references to the RelationshipInspector in the PopUpRendererSkin. The RelationshipInspector uses the AttributeInspector which by default, uses mx components like DateField. This has been an issue since 3.1, but now with 3.4, you're getting the error right away.

IsaiahAguilera

Thanks Dasa!
I understand now. To do this, do I just grab a copy of the skin from the api download and then comment out any thing in the PopUpRendererSkin.mxml that references the RelationshipInspector? I think I am missing something because I am still getting the error. Is there more involved then what I am doing?

Thanks,

Ive changed everything I can think of in the PopUpRendererSkin and I cannot get the runtime error to go away. I know I am probably missing something or not even doing it the right way but I can't get it working. I would hate to switch to the older api but that might be my only option for now. Any help would be appreciated.

Thanks for spending so much time on this Dasa!

I made the specified changes and I was still getting an error. So I did some digging and found that I had to also change the AttributeTableSkin and the RelationshipInspectorAttributeInspectorSkin. I was still getting an error so I just went looking for the calendar field in any file and it was in those two also.

 <fx:Component id="dateField">
        <!--<fieldClasses:CalendarField/> -->
   <fieldClasses:TextField minWidth="200"/>
        </fx:Component>

I wasn't sure how to reference the RelationshipInspectorAttributeInspectorSkin in the default.css so I just made a com.esri.ags.skins package and put them all in there to bypass the css and it got rid of my runtime errors. Did I do something wrong that I had to change those two files as well? I am not using those components at all I am just running the basic map still.

<ns:Map id="map">
  
 </ns:Map>

Anyways I am able to use everything either way now. I was just curious about the other two skins ans why I had to change those also.

Thanks,

DasaPaddock

I only had to make the changes I showed in my previous reply.

Did you name the css file default.css or defaults.css?

I also found in testing, that just changing the css file doesn't trigger a rebuild, so I had to either do a clean or make a small edit to the mxml to force a rebuild.

IsaiahAguilera

That was it. I used "default" instead of "defaults". Renaming it and running a clean made it all work. Thanks for all of your help with this. It is very appreciated.

I'm using Flash Builder 4.7. The above fix was working until I went and updated eclipse. now I have 5 new warnings. Any ideas on which skin could be causing them?

The style backgroundColor is only supported by type mx.containters.Panel with the theme(s) 'halo,spark'.
The style borderAlpha is only supported by type mx.containters.Panel with the theme(s) 'halo,spark'.
The style borderColor is only supported by type mx.containters.Panel with the theme(s) 'halo,spark'.
The style cornerRadius is only supported by type mx.containters.Panel with the theme(s) 'halo,spark'.
The style corner Radius is only supported by the type mx.coreContainer with the theme(s) 'halo, spark'

so it appears the upgrade corrupted my application. I am able to apply this fix to all new mobile projects and it clears the warnings I get. My original project still has warnings regardless of what I do, I've had to recreate it.

However even with this fix I can not get a release build to export using 3.4 or 3.5. I've described my error messages in another thread:
http://forums.arcgis.com/threads/93772-Flex-Mobile-using-3.4-or-3.5-compile-problems?p=334705&posted=1#post334705

My guess is these issues are related. I've gone back to using the 3.3 api, it works flawlessly for me.

IsaiahAguilera

After that thread I still had release build problems also. I was able to solve it by making an additional change to the AttributeInspectorSkin. I had to change the memoField to use a text field. This solved my problem, not sure it will solve yours but your welcome to try.

<fx:Component id="memoField">
            <fieldClasses:MemoField minWidth="200"/>
</fx:Component>

Change To:

 <fx:Component id="memoField">
            <fieldClasses:TextField minWidth="200"/>
</fx:Component>

Also I am on 3.4 and I am no referencing the mx.swc or sparksskins.swc at all. Everything compiles and release builds fine.

Hope This Helps,
