I'm working on the eSearch widget (last version for 2.5 viewer), and I think some of my custom code has caused an issue with the widget.
Run the application from Flash Builder 4.6 and the very first query I try to run from the eSearch widget returns an error that it cannot perform the query. However, if I hit search again, it will conduct the query.
In addition, if I run the application, I cannot use the Graphical search until I run a Text search query. You try to select a geometry to select and it will not allow you to select a graphic. However, like I said, once a successful query runs from the Text search, the tool works as it should.
