When we add
        <property name="layoutManager.groupingPropertyNames">
	      <list>
	        <value>groupName</value>
	      </list>
	    </property>
for grouping elements as 'Equipment' ,'Travel' etc, we are getting following exception

java.lang.RuntimeException: Exception evaluating expression: data[newBudgetLineItems][0].groupName

is this because of no data in object?
