Hi,
in my app i have a RefreshingView that gets a label an a TextField
subclass MyAjaxTextField.
<form wicket:id="form">
<table cellspacing="0" class="dataview">
<tr>
<th>Beschreibung</th>
<th>2004</th>
</tr>
<tr wicket:id="simple">
<td><span wicket:id="description">[description]</span></td>
<td><input type="text" wicket:id="value"></input> </td>
</tr>
</table>
</form>
##################################################################################
public class MyRefrechingView extends RefreshingView{
[...]
protected void populateItem(Item item) {
// populate the row of the repeater
MyForm form = (MyForm)this.getParent();
IModel position = item.getModel();
final Label description = new Label("description", new
PropertyModel(position, "description"));
item.add(description);
final MyAjaxTextField valueField = new MyAjaxTextField("value",
new PropertyModel(position,"output"));
valueField.add(new MyAjaxFormSubmitBehavior(form,"onchange"));
valueField.setOutputMarkupId(true);
item.add(valueField);
}
}
##############################################################################
public class MyAjaxTextField extends TextField{
MyOnChangeAjaxBehavior ajaxBehavior = new
MyOnChangeAjaxBehavior();
public MyAjaxTextField(String arg0) {
super(arg0);
}
public MyAjaxTextField(String arg0, IModel model) {
super(arg0,model);
//this.add(ajaxBehavior);
PropertyModel pm = (PropertyModel)model;
Position position = (Position)pm.getTarget();
if(position.hasFormula()){
this.add(new MyAjaxOnClickEvent("onclick"));
this.add(new MyAjaxOnBlurEvent("onblur"));
}
}
}
The Value of the TextField depends on some data stored at Position. It
could be a normal double value or a formula.
If i run the app, everything seems fine and all calculations and ajax
updateing seems to work but i got this exception:
58023 [http-8080-Processor25] ERROR org.apache.wicket.RequestCycle - there

What do i have to change to avoid these exception. I don't have a clue
where it comes from. Even the debugger doesn't help.
Hope one of you could?
