[Dltk-dev] DelegatingFoldingStructure and IFoldingBlockProvider

[Edgar Espina <espina.edgar@xxxxxxxxx>]

Greetings,

 I'm writing some parts (actually all the code :D) from my ANTLR IDE. Starting with DLTK2.0 the AbstractASTFoldingStructureProvider class was deprecated in favor of DelegatingFoldingStructure and IFoldingBlockProvider which is good. The default implementation PartitionIdFoldingProvider does a great work integrating the folding regions with the already created partitions.
 I would like to know if anyone is using these new two classes, because I found three issues:
  1) The initial collapse could not be ensured. If I set the initial collapse to true, the folder's region start collapsed but after a few seconds their are expanded.
  2) It doesn't matter where the user start the editing all folded region will be expanded all the time.
  3) I found some NPE in the PartitionIdFoldingProvider#reportRegions method, but some unknown reason the "requestor" field is null. Unfortunately, I could not explain this behavior as far as I know the DelegatingFoldingStructure is the only class that calls to PartitionIdFoldingProvider's method I the execution flow seems to be OK (I could not see any new thread). I'll try to isolate and identify the specific issue here.

For 1) and 2) I remember this bugs were present in AbstractASTFoldingStructureProvider, but then all them were fixed. Could any one point me were to look for these issues?

Thanks in advance,
