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.

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.

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.
