[jira] Commented: (COCOON-1939) Stack overflow when inheriting from
block that alread inherits from another one
[ http://issues.apache.org/jira/browse/COCOON-1939?page=comments#action_12446406 ]
Daniel Fagerstrom commented on COCOON-1939:
-------------------------------------------
I found the problem with the latest patch and have hopefully solved that with a new patch. There still might be some problems left though. For example I don't think inheritance works in three levels. And also the inheritance of properties need some more review. I'll return to it.
I would appriciate if you could contribute extensions to the cocoon-blocks-fw-sample that illustrates the cases that you have had problems with this far. in a later step we should build unit test cases from the examples.

> Key: COCOON-1939
> URL: http://issues.apache.org/jira/browse/COCOON-1939
> Project: Cocoon
> Issue Type: Bug
> Components: - Blocks Framework
> Affects Versions: 2.2-dev (Current SVN)
> Reporter: Alexander Klimetschek
>
> There are problems with the following scenario: I have one Block A, another one B that has A as super-block defined and a third one C that has B as super-block defined.
> The super-relation between B and A works ok, but if you start in C, then forward to B, which in turn wants to forward to block A (all via the block:super: protocol), a stack overflow happens. It looks like he always thinks he is in C, so that block:super: from B will always get to B, thus creating an endless loop.
