Why do I have to add namespace=local. Having the namespace change on different is very confusing and difficult to remember. the namesapce="local" is needed or flatKey since one is in request and the other is local. <foreach name=r property="${queryResult}.rows"> <set name=flatKey value="" namespace="local"/> <foreach name=a list="${attributes}"> <set name=k value="${prefix}.\${a}.\${r}" /> <set name=v value="\${\${k}}" /> <get name=v><br> <append name=flatKey value="\${\${k}}" delim="."/> <get name=flatKey><br> </foreach> </foreach>
