I was just wondering if anyone else has experienced problems
with using Drag and Drop functionality after going to Flex Builder
3, beta 3? I have 3 projects that all use drag/drop in a similar
fashion, and ever since installing FB3 b3 they now error out no
matter what I try. My drag handler looks like the attached code,
and the error I get is this:
FB3 also opens up the ArrayList.as class, so its trying to
tell me something...
You can try looking at the exact line in ArrayList indicated
by the stack trace for clues as to what went wrong. If Flex Builder
is opening the file, then you're probably launching in debug mode;
this gives you an opportunity to examine the actual values of
variables right when the error occurs.
Glancing at the stack trace, it looks like your Product
constructor is creating an ArrayCollection based on an Array. You
may want to check for problems with the Array you're passing to the
Thanks for the tips. As it turns out, it is a bug that exists
in Beta 3 but it is fixed it some of the more recent nightly
builds. I grabbed the latest version of the SDK and it now works
like a charm. For any one who has similar issues, you can check out
the bug report here:
and just make sure that you grab the latest SDK build to avoid it.
