The code you have presented isn't very clear. Your Action, for example seems to declare the controlVO1 reference twice -- won't compile.
Are you trying to say that you have a list of objects within the ActionForm? Is it being placed in the session/request under the key "formList" -- 'cos that's how you are trying to retrieve it in the JSP. Why do you have the "getAttribute(...)" stuff? Also, what version of Struts are you using? Sri P.S. Repeatedly posting the same message doesn't assure a response. In fact it is a turn-off -----Original Message----- From: ashokd [mailto:[EMAIL PROTECTED]] Sent: Saturday, February 02, 2002 1:00 PM To: Struts Users Mailing List; Martin Gross Subject: Nested Tags Problem ....

I have a method in ActionForm private ArrayList mFormList = new ArrayList(); public Object[] getFormList() { return mFormList.toArray(); } public ArrayList getMyFormList() { return mFormList } public setMyFormList(ArrayList pFormList) { this.mFormList = pFormList } This ArrayList contian the ValueObjects. I am getting the instance of ActionForm in another Action Class and setting this variable (which is invoked before loading this page). Code in Action class: MyVO controlVO1 = new MyVO("600","10","100 O","10","1","2/5/1998","12/31/1111"," "); MyVO controlVO1 = new MyVO("600","10","100 O","10","1","2/5/1998","12/31/1111"," "); ArrayList alControl = new ArrayList(); TestForm testForm = (TestForm)aRequest.getSession().getAttribute("testForm"); if(testForm == null) { testForm = new TestForm(); } testForm .setMyFormList(alControl) ==== JSP ----- <nested:iterate name="formList" > I am getting the follwoing exception.... any suggestions.....
