Does pre-release 3.0 require Adobe FlashBuilder < 4.5? I am having trouble compiling with 4.5 - lots of errors

3.0 Prerelease only works with 4.5 and above.

I think in your case, maybe you have not added the API Library (the SWC file) yet? You need to download it separately - http://links.esri.com/flex-api/latest-download.

See http://resourcesbeta.arcgis.com/en/help/flex-api/concepts/index.html#/Getting_started/017p0000001q000000/ for how to include it in your project.

I extracted agslib-3.0b1-2011-12-16.swc from arcgis_api_for_flex_3_0.zip and placed it into the libs folder of ArcGIS-ArcGISViewerForFlex-flexviewer-3.0Prerelease-src-0-g16b7ba8.zip
This resulted in a reduced number of compile errors (25), but not zero.

agslib- 3.0b1-2011-12-16.swc ... flexviewer- 3.0Prerelease-src

That's the "3.0 beta 1" SWC. Try with the "3.0 Prerelease" SWC instead: http://links.esri.com/flex-api/latest-download

Could anyone suggest the tag and tag location used to enable the basemap thumbnails beyond the default defaultBasemapIcon.png?

Derek,

Are you talking about the Flex Viewer's MapSwitcher?... Because you are posting to the AGS Flex API forum post announcement for the 3.0 pre release API... Maybe you are looking for this documentation from the Flex Viewer 3.0 pre release:

Yes..sorry I mistakenly thought I was creating a thread rather than a reply to the pre-release announcement. Your link is what I was looking for. I will delete and repost.

Good forum. I like to solve problem in this forum.

Just tried 3.0 pre-release with our applications. I came across an issue of the 'GraphicsLayer' class no longer having 'units' as an attribute but don't think this change is mentioned in the release note?

Correct, the "units" have been removed (and it wasn't mentioned in the "prerelease" release note). This property was needed for the Map in a few edge cases where it wouldn't get the Units from the metadata of the first layer added to the map. At 3.0, the API is now figuring out the units based on the spatial reference, thus no more need for the "unit". At least that's what we were thinking...

What are you using the GraphicsLayer.units for?

Will it (at 3.0) just work fine if you remove those lines?

SarahBurgin

I was setting the units in relation to polygons that our application draws, which need to be accurately sized.

Yes, I did find that commenting out the affected lines of code for building with ArcGIS API 3.0 seems to work just fine!
