Milestone 3 FAQ
Overview
My menu entries keep disappearing
This is due to a bug in one of the dependencies of Spoofax, which sometimes throws a NullPointerException.
There is no known solution at the time, but for some people upgrading from Eclipse 4.2 to 4.3 decreased the problem occurrences.
As a workaround, you can restart eclipse with File->Restart.
Eclipse should restore all windows etc. and your menu should be complete again.
My builder is applied to the unanalysed, non-desugared AST. How can it be applied to the analysed, desugared AST?
Remove the (source) annotation from the action entry in your MiniJava-Menus.esv file.
This annotation tells Spoofax to apply a builder to the unanalysed source AST.
Without this annotation, the builder will be applied to the analysed AST.
Do not call desugar-all or desugar-after-all yourself in the builder.
Though this will give you a desugared AST, this AST will still be unanalysed and miss information you need for code generation.
