On project loading ExtraCompiler objects are created that might read the already existing ui_*.h files in the build directory. In this case, ExtraCompiler::setContent() is called, which will emit a signal about the modified content. Now GeneratedCodeModelSupport is a client of this signal and it forwards the changed contents to the clang code model. However, GeneratedCodeModelSupport objects might be created later and miss the initial signal emission, thus leaving the code model unaware of some unsaved files. Fix by notifying the code model at construction time of GeneratedCodeModelSupport.
