I have used this little trick several times today, maybe it will come in handy for you:

Wherever you are trying to use the current() function put in this XPath: local-name(current()) and you will know instantly what node current() is refering to.

current() for an expression box will typically be different than current() for a text box (or other control). This is because the context of the expression box is the container (table, section, etc) whereas the context of the text box is itself.

Xpath differently in expression box and text box

I have a drawing schedule. Under each drawing is a list of revisions and a list of revisions. When I create an issue I want to print, and store in the issue tree, the latest revision number.

This works in an expression box, but not in a text box (I get an error):

../../../../my:Drawings/my:Drawing[my:DwgNo = current()/my:IssDwgNo]/my:Revisions/my:Revision[last()]/my:RevNo

This does not throw an error, but then it does not produce any result either:

//my:Drawings/my:Drawing[my:DwgNo = ../my:IssDwgNo]/my:Revisions/my:Revision[last()]/my:RevNo

This produces the correct answer in the text box, but only for drawing 1, of course:

//my:Drawings/my:Drawing[my:DwgNo = 1]/my:Revisions/my:Revision[last()]/my:RevNo

If anyone has an idea I would be grateful to hear about it.
