I have request attribute set to batchProgressMetricsList and its an array list of an object called. I have AggregatedBatchProgressMetrics. Inside aggregatedBatchProgressMetrics i have a method called getBatchMetricsList which return an arraylist of object called BatchProgressMetrics. If i run it without the nested c:forEach tag, it would just run fine, but if i include the nested one it just fails. Can somebody please help me?

Thanks in advance. Almas

Don't try and XML-escape your code samples, SO's editor can do a much better job. What you've posted is unreadable. – Entremets 8/12, 2010 at 13:0

Try changing this:

items="${aggregatedBatchProgressMetrics["batchMetricsList"]}"

to this:

items="${aggregatedBatchProgressMetrics['batchMetricsList']}"

@Teador than why is this not marked as an answer? It would be nice. – Heft 5/1, 2015 at 8:57

Replace

<c:forEach var="batchProgressMetrics" items="${aggregatedBatchProgressMetrics["batchMetricsList"]}">

by

<c:forEach var="batchProgressMetrics" items="${aggregatedBatchProgressMetrics['batchMetricsList']}">

The doublequote was closing the items value too soon which resulted in invalid EL. You should have spotted this soon enough when using an editor with decent sytnax highlighting (like here on SO :) ).
