trouble with logic:iterate

i am trying to iterate through list of lists. "processMessageList" contains another list "errorList". errorList contains objects of type "ProcessMessage". following is my code.

<logic:iterate id="errorList" name="processMessageList" property="errorList">

<logic:iterate id="processMessage" name="errorList" type="gov.wi.state.dpi.discipline.entity.ProcessMessage">

<tr>

<bean:write name="processMessage" property="shortDescription"/>

</tr>

</logic:iterate>

</logic:iterate>

it gives me following error at the second logic:iterate loop.

Cannot create iterator for this collection

i guess it doesn't recognize name="errorList" as a collection in the second logic:iterate. any ideas?

Thanks.
