Flex SDK 4.5 support?

RoyceSimpson

All clear to load up Flash Builder 4.5/SDK 4.5 for use with the API?

For different topics, it is usually better to create new "threads" 🙂

HI bjorn..

on a different tpic... is there any sample of connecting/using SQL server in Flex..?
Thanks

The existing 2.3.1 release works with Flex SDK 4.5 (and 4.5.1) - though there's a few things to keep in mind, especially if working with mobile (Android, iOS) devices.

There is a good article on the Adobe Developer connection about "Building an Android and iOS mobile mapping application using the ArcGIS API for Flex"
http://www.adobe.com/devnet/flash-builder/articles/mobile-mapping-app-arcgis.html

Recently, Adobe TV also posted an episode about "munitracker" showing the existing Flex API on multiple devices:
http://tv.adobe.com/watch/adc-presents/munitracker-app-for-android-and-ios-built-with-flash-builder/
Related article: http://www.adobe.com/devnet/flex/samples/muni-tracker.html

But ... while it is possible to use the existing 2.3.1 with the Adobe Flex 4.5 SDK, our next version (2.4) will make it even easier, as well as better for mobile applications. Our plans are to release version 2.4 next month (July).

As we are about to start the actual development of a new project that will use the latest Esri Flex API, we are wondering if there are any progress in respect to the official Esri support for Flex 4.5.

Is there a likely time frame for the Esri certification of the Flex 4.5 SDK?

Are there any major issues (that require extensive work-around coding) encovered so far while using Flex 4.5 SDK in conjonction with the Flex API 2.3.1?

Thank you

Yohan,

You can create a swc that uses the ArcGIS Flex swc, but you'll need to make sure that in your library project, you set the link type to "external" under the Library path. You'll then just need to include both swcs in your application project.

Thanks bjorn for your response, although after some debugging I realize now it's not an issue with the SDK. What I'm trying to do is put the sample in a separate library, which I could then include in all different Flex projects (i.e. AIR, FlashPlayer, mobile). To avoid repetition. I found that when I move everything out of the library, then everything will work fine. I think I can't include a SWC within a SWC. Yes I am kind of new to Flex so I apologize, I should have debugged more.

As for why it worked with my FlashPlayer project, I just realized that if you don't do a clean build, Flash Builder will run your latest working SWF if you have errors with your current one.. After a clean, I was getting the same error in this project as well.

I have an issue when trying to reproduce the WMS layers on/off sample for a Desktop application.

It works fine for me:)
I created a new Project (Application type: Desktop), added the 2.3.1 swc, added the com.esri.ags.samples, and copied in the WMS sample.

Is this your first Desktop AIR project?
Have you tried any other samples and got them working?
Did you make any other changes to the Flex Project?

YohanBienvenue1

I have an issue when trying to reproduce the WMS layers on/off sample for a Desktop application. The FlashPlayer version works fine but for the Desktop I always get this error: "Error: Skin for poc_desktop0.WindowedApplicationSkin2.Group3.contentGroup.HDividedBox7._poc_desktop_Map1.StaticLayer13.ScaleBar24 cannot be found."

flex_sdk_4.5.0.17689
arcgis-api-for-flex-2.3.1
Flash Builder 4.5
Adobe Air 2.6.0.19140

I tried adding the arcgis-api-for-flex-2.3.1\skins\src folder as a source attachment for agslib-2.3.1-2011-04-26.swc in the "Flex Library Build Path" in Flash Builder, but it didn't help.

Is this a 4.5 SDK issue or do I have to do something special for Air?

Royce,

The 'length' property on an Array is not Bindable, and yes this warning comes up when using the 4.5 SDK.

You would have to use a function as source of binding expression to make it work. Something like:

<fx:Script>
        <![CDATA[
                       
            private function getSliderMaximumAllowedValue(lods:Array):Number
            {   
                return lods.length - 1; // using this function as the source of data binding expression as the length property of lods(Array) is not bindable
            }
        ]]>
</fx:Script>

<mx:VSlider id="slider"
                    height="130"
                    alpha="{getStyle('contentBackgroundAlpha')}"
                    dataTipFormatFunction="formatSliderDataTip"
                    dataTipPlacement="right"
                    enabled.disabled="false"
                    enabled.disabledWithSlider="false"
                    enabled.normalWithSlider="true"
                    includeIn="normalWithSlider,disabledWithSlider"
                    liveDragging="false"
                    maximum="{getSliderMaximumAllowedValue(hostComponent.map.lods)}"
                    showDataTip="true"
                    snapInterval="1"
                    tickColor="{getStyle('color')}"
                    tickInterval="1"
                    tickLength="3"
                    tickOffset="-3"
                    tickThickness="1"
                    value="{hostComponent.map.level}"/>

Hope that helps.

Thanks for reporting this.

Ok, I've just re-imported a 4.1 sdk (flashbuilder 4.5) project into a 4.5 sdk one, made a couple adjustments and the only outstanding issue so far... is in the esri sample supplied "NavigationSkin.mxml" (in other words, I haven't modified this file).

...
  <mx:VSlider id="slider"
     dataTipFormatFunction="formatSliderDataTip"
     dataTipPlacement="right"
     enabled.disabled="false"
     enabled.disabledWithSlider="false"
     enabled.normalWithSlider="true"
     height="160"
     includeIn="normalWithSlider,disabledWithSlider"
     liveDragging="false"
     maximum="{hostComponent.map.lods.length - 1}"
...

returns the following warning message:
Data binding will not be able to detect assignments to "length". NavigationSkin.mxml

Doesn't seem to be a deal breaker, but that's the only outstanding issue when going to SDK 4.5.

EDIT:
And here...

<esri:QueryTask id="queryTask" url="{mapLayer.layerInfos.length - 1}" useAMF="false"/>

returns the same warning message:
Data binding will not be able to detect assignments to "length".

thank you very much mehu11111 !! 😉
It's perfect now !

To fix widget Minimize issue in 4.5, change <s:Resize to <mx:Resize in WidgetTemplateSkin.mxml as shown below":

  <s:Transition fromState="open" toState="minimized">
            <s:Sequence>
                <s:Fade duration="100" target="{widgetLabel}"/>
                <s:Fade duration="100" target="{headerToolGroup}"/>
                <s:Fade duration="100" target="{contentGroup}"/>
                <s:Fade duration="100" target="{widgetFrame}"/>
                <mx:Resize heightTo="30"
                          target="{hostComponent}"
                          widthTo="100"/>
                <s:Move easer="{bounce}" target="{icon}"/>
            </s:Sequence>
        </s:Transition>
        <s:Transition fromState="*" toState="open">
            <s:Sequence>
                <s:Move target="{icon}"/>
                <mx:Resize heightTo="{hostComponent.widgetHeight}"
                          target="{hostComponent}"
                          widthTo="{hostComponent.widgetWidth}"/>
                <s:Fade duration="100" target="{widgetFrame}"/>
                <s:Fade duration="200" target="{widgetLabel}"/>
                <s:Fade duration="100" target="{contentGroup}"/>
                <s:Fade duration="100" target="{headerToolGroup}"/>
            </s:Sequence>
        </s:Transition>
        <s:Transition fromState="open" toState="closed">
            <s:Sequence>
                <s:Fade duration="100" target="{widgetFrame}"/>
                <s:Fade duration="100" target="{widgetLabel}"/>
                <s:Fade duration="100" target="{headerToolGroup}"/>
                <s:Fade duration="100" target="{contentGroup}"/>
            </s:Sequence>
        </s:Transition>
    </s:transitions>

I try new flex SDK 4.5 and I find one problem with widget minimizing.
If I click on minimize icon I get this :

I also have exactly the same problem. Because I'm totally new to ArcGIS-Flex I appreciate an workaround or something like that.

Thanks for your feedback.

We're having trouble with the pinch zoom in an app we've created for android using flex 4.5 and agslib 2.3.1. If you pinch slowly, it seems to interpret the movement as a pan until you let go, and then it zooms.

This issue is reproducible with 2.x of the api and with 4.x of the Adobe skd. not specifically tied to 2,3.1 and 4.5.
This issue is being worked upon.

Also, are there any plans to include the magnifier functionality from silverlight in flex? We have a customer chomping at the bit for this.

No. No plans for this one.

And finally, I'm using the legend component and I'd like to change the skin, whenever I create a new skin based on the legend and create as a copy of com.esri.ags.skins.LegendSkin I get an error that says "The source for the skin "{0}" cannot be found." Am I missing a skin library?

see http://forums.arcgis.com/threads/28487-PopUps#10 for configuring your Flashbuilder to create copy of skins used in ArcGIS API for Flex.

Thanks, Mehal.

First, for others, we've run into very few problems with agslib 2.3.1 and flex 4.5 sdk. Our entire product line hasn't moved over yet but our mobile app contains a lot of our core functionality. So far everything seems to be working just fine. We had to change the parameters for our geometry services from graphics to geometries but other than that I don't think we've changed anything.

We're having trouble with the pinch zoom in an app we've created for android using flex 4.5 and agslib 2.3.1. If you pinch slowly, it seems to interpret the movement as a pan until you let go, and then it zooms. I noticed this also happens on the ESRI app in the market from the dev summit. However the apple app works perfectly, I'm assuming since it's a native app. Am I doing something wrong? I tried setting mouseEnabled to false on the map, I also tried listening to the touch and mouse events and using event.preventDefault in the mouse move event if there were two touchpoints on the map but neither of these worked and I'm sure there must be an easier way. If you need me to provide any code please let me know but I'm pretty sure you'll see the same functionality on a very simple app that just displays a map.

Where can we post problems with ESRI behavior on mobile in flex 4.5? We have an app we're packaging with Adobe AIR and we're having trouble with the pinch zoom functionality.

You can post it here.

Where can we post problems with ESRI behavior on mobile in flex 4.5? We have an app we're packaging with Adobe AIR and we're having trouble with the pinch zoom functionality. Can someone point me in the right direction for getting some information? Our CEO is talking about scraping the flex project because of this single issue and I really, really don't want to do that...

We are still in the process of verifying 4.5 support. We should have a full report next week. If you want to be on the safe side, I'd recommend holding off.

As for the SDK:
As of now, the ArcGIS API for Flex seems OK with it, but in your applications there might be code that needs updating. If you are using the source code of the Viewer, I would recommend you stick with 4.0 or 4.1 for now.

As for the IDE:
It should probably be OK with Flash Builder 4.5, assuming that you use an SDK version as described above. But again, we are still in the process of testing and verifying.

Looks like if you don't use sdk 4.5, design mode is broken in Flash Builder 4.5.
