I am trying to setVisible on a Fragment using the
AjaxFormComponentUpdatingBehavior object.
It doesn't seem to work. I've also tried this with a Panel and that's not
working either.
However, if I use a component, like a TextField, that works.
In my java, this is the pertinent code for my Form:
DropDownChoice dropDown = new DropDownChoice("dropDown", new Model(""),
choiceList);
add(dropDown);
final WebMarkupContainer container = new WebMarkupContainer("container");
container.setOutputMarkupId(true);
final Text2Fragment text2Fragment = new
Text2Fragment("text2Fragment",
"text2FragmentId");
container.add(text2Fragment);
add(container);
dropDown.add(new
AjaxFormComponentUpdatingBehavior("onchange")
{
protected void onUpdate(AjaxRequestTarget
target)
{
target.addComponent(container);
text2Fragment.setVisible(false);
}
});
My fragment:
private class Text2Fragment extends Fragment
{
public Text2Fragment(String id, String markupId)
{
super(id, markupId);
TextField text2 = new TextField("text2");
add(text2);
}
}
My HTML:
<tr>
<td>DropDown:</td>
<td><select wicket:id =
"dropDown"></select></td>
</tr>
<tr>
<td>Text 1</td>
<td><input wicket:id="text1"></td>
</tr>
--spaces in span are for nabble
<sp an wicket:id="container" >
<sp an wicket:id="text2Fragment"></sp
an>
</sp an>
<tr>
<td>Text 3</td>
<td><input wicket:id="text3"></td>
</tr>
My Fragment:
<wicket:fragment wicket:id="text2FragmentId">
<tr>
<td>Text 2</td>
<td><input wicket:id="text2"></td>
</tr>
</wicket:fragment>
If I put the text2 TextField in place of the fragment, the control
successfully
disappears. I want a fragment so I can also remove labels, et al.
I'd appreciate any feedback on what I'm doing wrong.
