Yeah, it is unfortunate the player doesn’t tell you what was bad. Usually, it means a value was NaN or negative. The stacktrace says that a buttonskin is still being rendered. Check your sizes and styles

Problem is, seems like everytime I go to test a module or component, I am getting this: ArgumentError: Error #2004: One of the parameters is invalid. First, if Adobe is reading, this error is completely useless. There is no hint on WHAT has the invalid parameter. Googling the issue comes up with a dozen or so people with 'the answer' which does not pertain to my project at all. After commenting out almost everything I seem to find that Buttons are the issue (after reading all the error jargon under the error code). That worked for one of my views, however I commented out all the buttons in a new view and it threw the error still. Anyone out there found a good way to find out what has an invalid parameter? Here is the full error.

Also, does this mean the skin is always required? What other parameters are invalid. Here are all my buttons in the view and their parameters (also keep in mind it all worked perfectly in Flex3): <s:Button label="Go!" click="joinRoom(roomsCB.selectedItem.roomID);" enabled="{roomsCB.selectedIndex!=-1}" /> <s:Button label="View Profile" click="viewProfile(chatterList.selectedItem.username)" enabled="{chatterList.selectedIndex!=-1}" /> <s:Button label="Report" click="reportAbuse(chatterList.selectedItem.username)" enabled="{chatterList.selectedIndex!=-1}" /> <s:Button label="Send" click="sendMessage(chat_txt.text);" id="chatSend_btn" enabled="false" /> Help...this is annoying :) -- Alex Harui Flex SDK Team Adobe System, Inc. http://blogs.adobe.com/aharui
