Hi, I think there'll be a way to solve this in Tapestry 4.0. Meanwhile, I wrote a component that solves this problem. It's called SafeForeach. It caches the list you pass on to it so it will rewind correctly even if you make changes to the list on a listener method. Just now uploaded it to Tassel.

I'm new to Tapestry... trying hard to make a transition from WebObjects :) Here's my problem: I have a List of Strings through which I iterate, displaying one checkbox for each item in the List. In the form's submit action method, I add an item to the List. This is what happens after the first submit: You have clicked on a stale link. Rewind of form Home/$Form expected only 1 form elements, but an additional id was requested by component Home/$Checkbox. I suppose that the "1 form element" mentioned is the form's submit button. Any hints/clues/suggestions? What am I doing wrong here? Thanks! The code: public class Home extends BasePage { private List<String> someList = new LinkedList<String>(); public String listElement; public void formSubmit(IRequestCycle cycle) { someList.add("hooohaw"); } public boolean isCheckboxSelected() { return true; } public void setCheckboxSelected(boolean val) { } public Iterator<String> getSomeList() { // someList.add("hooohaw"); // putting this here instead of in formSubmit results in the same error return someList.iterator(); } } The HTML: <html> <body> <form jwcid="@Form"> <input type="submit" jwcid="@Submit" value="Submit" listener="ognl:listeners.formSubmit"/> <span jwcid="@Foreach" source="ognl:someList" value="ognl:listElement" > <input type="checkbox" jwcid="@Checkbox" selected="ognl:checkboxSelected"/> </span> <br/> </form> </body> </html> The environment: JDK 1.5.0_02 Tapestry 3.0.3 Windows XP Tomcat 5.5 --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
