Hi:
Sorry, this was my fault.
I am learning while trying to work. Now, I know the problem is not related to Cocoon, but since I think many other people on the list will benefit for this. I decided to post the solution:
The JDO specification said (chapter 14.6.1 page 105): <snip> 14.6.1 Query Execution
The Query interface provides methods that execute the query based on the parameters given. They return an unmodificable Collection..... </snip>
The last sentence is the root of the problem. I got this Collection and tried to modify it by adding a new row to the woody repeater. This is why I got the error described in the first mail of the thread.
At this point Flow+Woody+OJBwithJDO is working fine. I will continue the
tests. :-D
Interesting point to know, but I'm not sure this is _the_ reason. Looking at the exception, it looks more like a JXPath problem (cannot find a property write method or something like that). Or is there another chained exception that you did not post?
