Hahahahaha!
Now that that's out my system, yes, I tend to have similar experiences with you in this group. I think there's just a HUGE number of people here who are novices and don't know very much about Flex that ask questions, and very few "experts" that can answer 90% or more of people's questions. There's a lot of "good noise", if that makes any sense. So whenever someone finally posts a response (whether it's the OP or someone else), the floodgates open; people think there may be a genuine issue here. Of course, there are lots of problems that people are having, but so many problems are the same and can be solved by doing a simple search for the solution. Meh. Oh, and I would still consider myself a novice. If I were to solve your problems, A) Would it solve your problem if the event fired on a Click event? Probably not the best way to solve it... looks like a good temporary patch to me.

(was:Custom Currency itemRenderer) Really? Nobody has any input? I'm really at a loss of what to think about posting in this group. The people and information here are a wonderful resource, but I've posted 5 or 6 questions here and every single one of them initially received no replies. They didn't get any feedback at all until I responded to my own post once or twice asking again for help. Soooo... am I to assume I'm asking questions that are too advanced for anybody to answer? Not advanced enough for anybody to bother? Questions that have been asked enumerable times by other users and I just missed the previous answers? Or am I truly the first person to ever experience the issues I post about? Maybe I'm being too wordy and people get overwhelmed? Or am I not being wordy enough and people don't understand the problem(s)? I try to write very succinctly, and include source code when I can (typically reduced to exactly the components I'm having trouble with so we're not dealing with an entire app). I try to write subject lines that would be meaningful, rather than just a generic "Help!". I feel like I'm doing everything I can so anyone who wants to help won't waste their time dealing with either a lack of information or superfluous flack. I try to wait a fair amount of time so folks on digests, et al, have had a chance to view my posts. I try to thank anyone who does take the time to respond, even if the response doesn't directly solve the issue. I try to reply to other people's posts that involve aspects I have some experience with. I try to be a good group citizen. But still no one responds. I'd love to know what I'm doing wrong. --- In flexcoders@yahoogroups.com <mailto:flexcoders%40yahoogroups.com> , "carl_steinhilber" <[EMAIL PROTECTED]> wrote: > > Hello, > > I'm trying to build a itemRenderer for a currency field in a DataGrid > in Flex 2.
