Hello,
I've just come across wicket and started playing around - so far, I encounterd
some issues:
My first issue is:
Given a table and a Panel:
//SomePage.java
private TablePanel tp;
tp = new TablePanel("tablePanel",columns,new
PersonBeanProvider(searchFilter),12);
//TablePanel.java
class TablePanel extends Panel{
public TablePanel(String id, final List<IColumn<PersonBean>> columns,
PersonBeanProvider personBeanProvider, int rowsPerPage) {
super(id);
AjaxFallbackDefaultDataTable<PersonBean> table = new
AjaxFallbackDefaultDataTable<PersonBean>("table", columns,personBeanProvider,
12);
add(table);
}
}
And the html:
SomePage.html
(...)<span wicket:id="tablePanel"></span>
TablePanel.html:
<wicket:panel>
<table cellspacing="0" wicket:id="table">[table]</table>
</wicket:panel>
Everything is fine. But: If I introduce a form for modifying "searchFilter" (a
String to be passed) in this way:
searchField.add(new AjaxFormComponentUpdatingBehavior("onChange"){
@Override
protected void onUpdate(AjaxRequestTarget target) {
tp = new TablePanel("tablePanel",columns,new
PersonBeanProvider(searchFilter),12);
tp.setOutputMarkupId(true);
target.addComponent(tp);
}
});
I get an error _after_ submitting the form - what may be wrong here?
Thanks,
Keep smiling

that you have added a component in code but forgot to reference it in the
markup (thus the component will never be rendered).
