Re: [Xsltforms-support] xforms context function

Alain,

Here is the test case for the xforms context function.  The sample allows a user to edit the title and author of a book.  The data is copied to a separate instance for editing and then, if the user decides to save the changes, the original values in the first instance should be replaced with the modified values from the second instance.

Let me know if I can help further.

Chris

Can you please provide a full test case ? It would surely accelerate 
debugging.

Thanks!
