Concerning the first point, I will give you the patch that fixes the problem, but I don't in which form you want it. Do you want the method only or the whole class ? Where do I have to send it ? To the mailing list as attachment or directly to your personal address ? Concerning the second point. I will give you a proposition tomorow because now I am at Home :-). I would like to find a more elegant solution than the proposed one. My idea is to call the method Constants.getSignatureSpecNSprefix() into XMLUtils.createElementInSignatureSpace() instead to use the static variable (that can be supressed). I didn't check if this solution is possible, I will do it tomorow :-) May be you have an idea about it... I will also test these proposed solutions in the context of my application. Regards. Yvan
Thanks for the debugging session.
The first problem you have solved it great, can you send me a patch
with the fixes?.
The second one is more tough.
The easier solution will be let the Init.init() call a static function
XMLUtils (like reReadVariables). So the XMLUtils initialize the static
data.
This way we can use the static for caching and always getting the
correct behaviour.
What do you think?
