I'm not sure what you expect the value to be? Also, I don't see
t:context in the checkbox documentation, does that do something?
You are having trouble because you have a list of values going out,
but only a single value coming back in. For each checkbox selected in
the UI a value is passed back to the component. It calls the setter
for each value, overwriting the previous value and leaving you with
the last only the last one.
Try adding a setter for your property and collect the checked values in a list.
something like:
${item}
/** keep track of loop iterations */
private Integer listIndex;
/** loaded with selected checkbox values */
private List selectedItems;
/**
* Called with the form is posted for every checkbox that is checked.
* Use the listIndex to grab the right value from the original list.
**/
public void setCheckbox(boolean set) {
if (selectedItems == null) selectedItems = new ArrayList();
selectedItems.add(list.get(listIndex));
}

That sounds very familiar. Please have a look at this bug report: https://issues.apache.org/jira/browse/TAP5-869 Try it set the defer parameter of your submit component to false.

Re: Dynamicly Created Checkboxes
I think you should write own component to support that.
${item}
processSubmit:
request.getParameters("xxx");

Dynamicly Created Checkboxes
Hi all,
I am trying to get the submit results of a dynamic set of checkboxes
and I'm stumped.
http://tapestry.apache.org/schema/tapestry_5_1_0.xsd";>
${item}
public class Test {
private final String[] list = new String[] { "Abc", "Defg", "Hijkl", "Mno" };
@Property private String item;
@Property private boolean checkbox;
public String[] getList() {
return list;
}
}
If I simply add "onSuccess()" I only get the result for "Mno". Adding
one or more parameters (for item and checkbox) doesn't seem to work. I
tried various other methods and combinations but nothing seems to do
the trick.
How do I do this?
Cheers,
Hilco
