nested logic:iterate

[raamam]

In our application we have action classes like this:

class TaskActionForm
+String taskId
+String taskName
+ArrayList subTasks

The ArrayList 'subTasks' contains SubTaskActionForm instances

class SubTaskActionForm
+String subTaskId
+String subTaskName

The JSP gets an ArrayList of TaskActionForms. My objective is to iterate through the ArrayList to print the task details. If a task has subtasks then I need to get the ArrayList of subtasks and print them too.

I am new to struts and am confused on how to achieve this with nested <logic:iterate>. Can someone help me? Thanks.

Hey.. I have managed to do it. I am posting it here for the benefit of newbies like me:


<table>
<logic:iterate id="TaskVar" name="AttributeKey" type="TaskActionForm">
<tr>
<td><bean:write name="TaskVar" property="taskId" />
<td><bean:write name="TaskVar" property="taskName" />
</tr>
<logic:iterate id="subTaskVar" name="TaskVar" property="subTasks" >
<tr>
<td><bean:write name="TaskVar" property="subTaskId" />
<td><bean:write name="TaskVar" property="subTaskName" />
</tr>
</logic:iterate>
</logic:iterate>

You can also try nested:iterate tag, then you can skip the name attribute and just have property attribute; this will work if you either have nested:form or nested:root tag for you top level bean.
