ArcGIS API for Flex 2.0 Beta is now available

BjornSvensson

The Flex API 2.0 beta is now available at http://resourcesbeta.esri.com/content/arcgis-api-flex

If you don't read any other documentation, you might want to
at least read these "Three Potential Initial Gotchas":

1. Requires Adobe Flex 4 SDK.
2. You should use Flash Builder 4 beta 2 as your IDE.
3. If connecting to a 9.3 server, you need to set the useAMF property to false for Query, Geoprocessor and FeatureLayer.

Thanks guys!

Are there any samples available for the new Clusterer functionality?

BjornSvensson

In the API Library download (the "zip") is a rough/draft cluster sample called ClusterFunction.mxml. We haven't included it in the list/TOC of samples online because our clustering implementation is still a bit rough and the sample isn't that great. There might be a few API changes to the first beta when it comes to clustering ...

To see the samples, either compile it in FlashBuilder or go to:
http://help.esri.com/en/webapi/flex/samples/index.html?sample=ClusterFunction

Any feedback on clustering is most welcome. Before the final release we will have documentation and more samples.

I see ClosestFacility.mxml and the next one is CustomLODS.mxml.

BjornSvensson

Sorry my bad - that was an old sample. I've removed it.

BjornSvensson

The sample is called FeatureLayerClustering and you can see it in action at http://help.esri.com/en/webapi/flex/samples/index.html?sample=FeatureLayerClustering

Just noticed a bug on that, and possibly all the sample pages.
Try moving the mouse from the TOC panel over onto the map. Bam, scroll bars appear! Even worse if you move the mouse into the map pane from the bottom. If you do it slow enough, the scrollbar flickers on and off a million times until you've passed through! Perhaps related to the problem I'm having? (see most recent thread)

BjornSvensson

Yes, that is a problem with how we are presenting the individual samples inside our Samples Explorer in regards to those scrollbars. For now, you can also go straight to the sample in action by going directly to the SWF.

For example, instead of
http://help.esri.com/en/webapi/flex/samples/index.html?sample=FeatureLayerClustering
go to
http://help.esri.com/en/webapi/flex/samples/FeatureLayerClustering.swf

I followed the instructions to add the FB 4 beta 2 SDK and the Flex API 2.0 update 1 to Flex Builder 3. When trying to run an application I amd getting errors

"1046: Type was not found or was not a compile-time constant: Matrix 3D"

or ... GraphicsStroke, or Vector3D, or Number (73 errors in all).

Was I supposed to copy the 2.0 (not update 1) prior to the update? Is this a problem with the API or with my Flex install?

Any help would be appreciated. Thanks

BjornSvensson

Not sure about your specific error, but ... while it might be possible to use Flex Builder 3, we recommend developers use Flash Builder 4.

See the "Requirement Changes" at http://help.esri.com/en/webapi/flex/help/index.html#migrating.htm

As for the SDK, you would only use the "Update 1" version of the API Library.

RebeccaStrauch__GISP

Unfortunately department policy is not to use FB 4 since it's still in beta. I figured I could sneak it by if I just used the SDK beta. But I think I'm going to try it on my personal laptop to see if I can get it to work there. Hopefully that will do the trick. 😉

DasaPaddock

If you're using the Flex 4 SDK in FB3, make sure you set the minimum flash player version to 10.0.0 in your project settings.

RebeccaStrauch__GISP

I will double check that setting once I'm back in the office and check it out again. That is probably my problem.
Thanks

Where do I put the code for the FeatureLayerClustering. I tried inserting it in the ViewerContainer.mxml, but I think it is covered up by the layers in the config.xml. That is one of things I have struggled with. The new API seems to take a different approach from previous versions and general coding in FLEX.

Thanks.
