CURRENT always refers to the current loop. You are trying to access the outer loop's current which is the root cause and will cause index related issues.
One way of maintaining the index in case of multiple nested loops is to keep a parameter to track index for different loops. This is stored in pyForEachCount parameter. Before entering the LoopB you can do a property set (param.LoopBIndex == param.pyForEachCount) and then use this index instead of Current.
Let me know if this helps :)
hi rawap,
thanks for your explanation, but i wanna ask some question :)
are the param.Index1 & param.pyForEachCount a parameter variable ? can i change use property for param.Index1 ?
is the TempPage1.pxResult a Pagelist ?
thanks
This is something I have struggled with to accomplish as well - nice answer - 'stashing' the top-level COUNT value.
(This is actually a similar issue [and solution] to writing XSLT files; where you can have to 'stash' the outer-loop using variables).
Thanks !
Just out of interest : do we have to switch to using the 'internal' value 'pyForEachCount' - or couldn't we just stash the '<COUNT>' value at this level also ? (just a bit more consistent ?)
(of course I could just try it - but I'm being lazy and asking you !! :-) )
If Possible,Can you provide a screenshot.
