This works for me <s:iterator value="outerList"> <tr> <s:iterator> <td><s:property/></td> </s:iterator> </tr> </s:iterator>
My inner list is a list of Strings. This code gives me one innerList list per line Hope this helps, Steve -----Original Message----- From: DavidCAIT [mailto:dzaze...@cait.org] Sent: 02 June 2009 02:14 To: user@struts.apache.org Subject: Iterating over a List of Lists Hello, I am trying to use a nested List<List<MyObject>> with a Struts 2 Action and a JSP page. I would like to iterate through the JSP page to display the existing data, allow the user to edit the data, and post the form to a second Action. However, my second Struts Action always receives back a null list. I think that my indexing in the JSP page is incorrect. Does anyone have any suggestion about the correct way to index a nested list on the JSP page? This is how I am currently setting my indices: myList[0][0].property myList[0][1].property .... myList[1][0].property ....... My JSP code looks like: <s:iterator value="myList" status="outerStat"> <s:iterator value="myList[#outerStat.index]" status="innerStat"> <s:textfield name="myList[%{#outerStat.index}][%{#innerStat.index}].property" value="%{property}" /> </s:iterator> </s:iterator> Inside my second Struts action, I have the following code (the first action merely retrieves the list from the database and it works correctly since the JSP does populate correctly with all of the db records): private List<List<MyObject>> myList = new ArrayList<List<MyObject>>(); public List<List<MyObject>> getMyList() { return myList; } public void setMyList(List<List<MyObject>> numbers) { myList = numbers; } // this execute method is called when posting the form and always returns null // when the user is done updating the information // even though the first action correctly populated the JSP page public String execute() { for (List<MyObject> theList : myList) { if (theList == null) { System.out.println("received a null list"); } } } Thanks! -- View this message in context: http://www.nabble.com/Iterating-over-a-List-of-Lists-tp23824944p23824944.htm l Sent from the Struts - User mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
