CheckGroup form submission bug
So I've got what appears to be a very strange bug. I have a CheckGroup with a
ListView of Checks among other things. Everything seems to work fine if you
render the form and submit it without any errors the first time. However, if
you hit any errors (like not selecting any Checks), and are bounced back to
the form with an error rendered, if you select a Check and re-submit it, it
dies with the following error:
WicketMessage: submitted http post value [check22] for CheckGroup component
[14:slurpFormResults:resultPanel:group] contains an illegal relative path
element [check22] which does not point to a Check component. Due to this the
CheckGroup component cannot resolve the selected Check component pointed to
by the illegal value. A possible reason is that componment hierarchy changed
between rendering and form submission.
Root cause:
org.apache.wicket.WicketRuntimeException: submitted http post value
[check22] for CheckGroup component [14:slurpFormResults:resultPanel:group]
contains an illegal relative path element [check22] which does not point to
a Check component. Due to this the CheckGroup component cannot resolve the
selected Check component pointed to by the illegal value. A possible reason

at
org.apache.wicket.markup.html.form.CheckGroup.convertValue(CheckGroup.java:141)
etc..
Here's the code:
final ListView contactsList = new ListView(contactRepeater,
new
PropertyModel(this,
contacts))
{
private static final long serialVersionUID = 1L;
@Override
protected void populateItem(ListItem item)
{
ExternalContact p = (ExternalContact)
item.getModelObject();
Check check = new Check(selected, new
Model(item.getIndex()));
String mail = p.getEMailAddress();
if (mail == null)
{
p.setEMailAddress(p.getUserName());
}
check.add(new SimpleAttributeModifier(id,
p.getEMailAddress()));
// Create and style image
StaticImage image = new StaticImage(pic, new
Model(p.getImageURL()));
String pic = p.getImageURL();
Label picBlock = new Label(picBlock, new
Model());
picBlock.add(new
SimpleAttributeModifier(class, noPictureInactive));
item.add(picBlock);
item.add(image);
String emailLabel = new String();
emailLabel = p.getEMailAddress();
item.add(new Label(emailLabel, new
Model(emailLabel)));
item.add(check);
item.add(new SimpleAttributeModifier(for,
p.getEMailAddress()));
item.add(new SimpleAttributeModifier(class,
pictureContainer +
p.getType().toString()));
}
};
group = new CheckGroup(group, new ArrayList());
group.add(contactsList);
group.add(new CheckGroupSelector(groupSelect));
group.setOutputMarkupId(true);
Any help or ideas would be greatly appreciated. Thanks!

Re: CheckGroup form submission bug
if your listview is in a form you have to call listview.setreuseitems(true);

Re: CheckGroup form submission bug
hi nick, Thanks, this does fix this particular bug, but now I can't add items into the ListView. I'm trying to add items via AJAX, and with reuseItems turned on, it no longer adds the new items to the list like it should be. listview isn't designed like that, so this wont work with ajax. i stumbled over this a couple of month ago when designing an app to insert items with ajax into a listview, too. you have to create your own model to handel listviews, so for one you can reuse items but also do dynamic inserts which the listview will be aware of. you might take a look at the code to understand why it's not working. i solved this by creating a so-called 'FlexListView' with a 'FlexItemModel' containing 'FlexItems'. ;-) This View isn't using a List's index to reference the items but looks them up in a Map, so insert's don't effect the lookup to reuse Items. Hope you get an idea. Best regards, --- jan. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: CheckGroup form submission bug
Thanks a lot for the help! I don't suppose you could post some of these Flex objects?
