Hi.
I have a simple abstract panel that I display as a cell within an
AjaxFallbackDefaultDataTable. The panel has a label and a WebComponent that
shows an icon (based on passed in css).
The WebComponent has an AjaxEventBehaviour("click") added and whenever the
icon is clicked the handling is delegated to the concrete implementation
(think of the table cell having an action associated with it, such as edit
etc). Below is the (simplified) code of the LabelIconPanel...
public abstract class LabelIconPanel<T> extends Panel
{
private static final long serialVersionUID = 1L;
public LabelIconPanel(String id, IModel<T> model, IModel<String> text,
String cssIcon)
{
super(id, model);
Label label = new Label("label", text);
Component icon = new WebComponent("icon");
icon.add(new AjaxEventBehavior("click")
{
private static final long serialVersionUID = 1L;
@Override
protected void onEvent(AjaxRequestTarget target)
{
LabelIconPanel.this.onClick(target);
}
});
icon.add(new AttributeAppender("class", new Model<String>(cssIcon),
" "));
add(label);
add(icon);
}
public abstract void onClick(AjaxRequestTarget target);
}
_____________________
The panel is added to the table via a PropertyColumn like so...
new PropertyColumn<SomePojo, String>(new Model<String>("Some header"),
"someProperty")
{
private static final long serialVersionUID = 1L;
@Override
public void populateItem(Item<ICellPopulator<SomePojo>>
item, String componentId, final IModel<SomePojo> rowModel)
{
LabelIconPanel<SomePojo> labelIconPanel =
new LabelIconPanel<SomePojo>(componentId, rowModel,
new Model<String>(
rowModel.getObject().getPropertyValue()),
"icon-pencil")
{
private static final long serialVersionUID = 1L;
@Override
public void onClick(AjaxRequestTarget target)
{
// handle the icon being clicked
here...show a dialog to edit property etc.
}
};
item.add(labelIconPanel);
}
}
____________________________
The issue I am having is that when I sort the table via the header, the icon
in the above panel is no longer receiving the click event (for any rows).
If I revert the sort, the icons in each row work as expected. If I refresh
the page after sorting, the icons work as expected.
This is my first post on here as I am new to Wicket development, so any
pointers as to what might be going on or suggestions as to where I might
need to start looking would be appreciated.
