what is your "collection1" exactly, name/id/value of repeat control? or datasource that parent repeat control interator points to?

 

<xp:repeat id="repeat1" rows="30"
                    value="#{javascript:getArray();}" var="row"
                    indexVar="rowIndex">
                   <xp:repeat id="repeat2" rows="30"
                        value="#{javascript:return row;}">
                        something
                    </xp:repeat>

</xp:repeat>

nested repeat control should refer to "row" from parent repeat control as its own datasource...

 collection1 is name of the collection of the parent repeatControl. In your example that would be 'row'.

 

 

if syntax is right, then should check if "collection1" is really null or not, but you must have done that
or return a vector instead of a array, vector can be regonized by SSJS, but array can't, i guess, tried a couple times

ok, I'll try to do that

Thanks
