This is an older widget I know, and possibly a long shot, but has anyone been able to get this widget working in Flex SDK 4.6 and ArcGIS Viewer for Flex 3.0? Perhaps a better question might be: does anyone have an uncompiled version of the Selection Widget that will work in Flex SDK 4.6 and ArcGIS Viewer for Flex 3.0 out there and is willing to share? I am having the same issue that some others in this thread have experienced, namely the Unique Values list is not populating. My data is on an ArcGIS Server 10.0, and problem is happening with a couple of the example data sets as well (but not all of them).
Actually what happens is that it populates correctly the first time I click Get Unique Values but every time thereafter returns nothing. ("Processing: 0 of 1131" flashes briefly but the list does not populate.) Get Unique Values runs when I double click the field name for the very first time as well to add it to the selection query and the unique value list populates, but only that first time. I can manually type in the query and the rest of the functions work no problem, despite the fact that it was compiled for a different version. I have to shut down and restart FlashBuilder to get it to work again (one time, and then it's back to not populating the list). I've done a little bit of digging and wonder if it is related to paging in general (or the fact that "dispatchEvent" (found in the SelectionWidget.mxml and PagingQueryTask.as) has been deprecated)? I do need to be able to query (or select) on multiple fields within a single layer (similar to the Query Builder in Desktop).
Any suggestions would be much appreciated, thanks!
