Users of Apache Flex 4.10.0 (and later) have reported a problem when creating new Flex projects.  The Application tag erroneously contains the attribute 'layout="absolute.'"


As described in FLEX-33636 in the Apache Flex bug base, a manual workaround is to use the editor to remove the erroneous attribute. However, to avoid requiring you to fix every new project, Adobe has created a patch to one of the JARs in Flash Builder. The JAR does not work with Flash Builder 4.6.

  1. Download the embedded ZIP file (


  2. Shut down Flash Builder.

  3. Navigate to the folder <Flash Builder Installation Folder>/eclipse/plugins/com.adobe.flexbuilder.codemodel_4.7.0.349722.

  4. Save the existing codemodel.jar to another folder (in case you want to revert to the original later).

  5. Extract the codemodel.jar from the ZIP file and replace the existing codemodel.jar.
