In Flex 3 Beta I had no issues doing this, in Flex 3 GA it does not work and I'm wondering if any of you have seen this issue.
I have extended Module to MyModule and added code that I need. My Flex builder is setup into three projects. AppProject, ModuleProject, and FrameworkProject. My Framework is compiled to my.swc and is in the lib folder of both ModuleProject and AppProject. Both have the swc correctly setup in the project properties. When I open one of my Modules in code view it works great. But when I go over to design view I get an error message in the middle of the design view with the the text "An unknown item is declared as teh root of your MXML document. Switch to source mode to correct it." In the Problems view it shows a warning: Design mode: Cannot load my.swc (reason: ERROR: Load Verify). It may require classes (such as Adobe AIR components) that are not supported by design mode. Check the Eclipse error log for more details." This used to come up just fine in design view with Flex 3 beta. If I remove my.swc from my ModuleProject and instead add a new source file that points to the src folder of my FrameworkProject it works. But I don't want this as it causes compiles to be much longer and it is not the way I need it to work since our customers will be able to build their own Modules based off of our Framework and I don't want to give them anything more than a swc. Any suggestions? Thanks, Dale
