I have a navigator content extension which I am using to override certain IFolder and IFile objects and provide custom objects (adaptable to IResource) instead. This content extension is bound to the Project Explorer. I also have a lightweight label provider to decorate the custom objects if any of the IResource objects represented by its children have a problem marker.

The problem is that my incremental builder visits the folders containing the files to be built before visiting the files themselves. The end of each 'visit' by the incremental builder appears to trigger re-decoration of the resource. The custom folder objects are therefore re-decorated before all the files are built and the problem markers have been added.

How can I ensure that the custom folder objects are not re-decorated until the incremental build job has finished?

Any pointers would be much appreciated.

Thank you
