Hello: In this article from Adobe: http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_19323&sliceId=2
It says " When the <optimize> attribute is set totrue, it reduces the size of the Flex application's SWF by 10-15% by compressing the ActionScript code and removing all the trace statements. If you have optimize set totrue, then you will not see the trace statements in the output file. To see the trace during development, you need to set <optimize>false</optimize> in the flex-config.xml file." I'm using Flex Builder 2.0.1 (not the plugin version), anyone please tell me any place to configure that? Thanks a lot --------------------------------- Be a better friend, newshound, and know-it-all with Yahoo! Mobile. Try it now.
