Why does Flash Builder 4.7 freeze when I try to open an MXML file?
There is a bug in the Flash Builder compiler when processing MXML components that are nested so that a component has a child that contains a reference to the parent component's type. Adobe did send me a fix for this issue.
Steps to fix the issue:
- Close Flash Builder
- In Windows Explorer navigate to the c:/Program Files/Adobe Flash Builder 4.7/eclipse/plugins/com.adobe.flash.compiler_184.108.40.2069722/AIRSDK/lib
- Copy the compiler.jar file to a directory in case you need to replace it.
- Download the patched compiler.jar I received from Adobe to the directory above
- Start Flash Builder
