Subject Re: Woody Binding Selecting Rows
Date Tue, 02 Dec 2003 08:53:03 GMT

could you slide in the error you got?

things that come to mind (possible reasons why it goes wrong)
- jxpath fails on a setValue call with an xpath statement that contains 
a predicate (anyone that tested this on bare jxpath?)

even if that would work:
- the repeater-binding produces an additional row-index predicate for 
the setValue on the newly to be created node.  It just appends the 
[rowindex] but if there is already a predicate present then the syntax 
should be more like [(part that is there) and position()=new_rowindex]

actually the easiest way seems to be to remove the predicate from the 
statement just before doing the insert-phaze of the binding, ie. 
starting with counting how many rows there are left after delete (that 
count should also be regardless of predicates, so the additions get 
inserted at the end...)

hm, still in thinking and considering mode
