[Xsltforms-support] using calculated value in select1 itemset

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Hello,

I would like to calculate the labels appearing in select1, this might be 
possible using the xf:bind 'calculate' attribute.

However whilst the following example works, it only works if the 
caculated 'new_value' nodes are pre-existing in the instance.

My problem is that if the source of the data is an external source then 
the calculated nodes cannot be inserted prior to the calculation and so 
perhaps they should be created automatically?

Is there another way to handle this situation?
