[flexcoders] Array/ArrayCollection problem when migrating from Beta 3 to Flex 2 Final

Wed, 12 Jul 2006 06:02:40 -0700

Hi,
     This is Sreedhar. I am working with Flex Builder 2, Java Server Pages, and SQL Server 2005. Currently, I am working on "Search based on Keyword". When I execute the search through the JSP, I am able to see the results. I am having a problem when displaying these results in a Flex DataGrid. If my search yields only one result, the result is displayed in the DataGrid properly. However, if there are multiple results, the DataGrid is blank. I was able to get this to work in Beta 3, but after migrating to the final version, it no longer works. I am pretty sure that the problem has to do with this change that is listed on the changes page: Arrays are wrapped in mx.utils.ArrayCollection instances. However, taking this into account, I still can't fix the problem.
