Yes it did compile yesterday but the error occured when I updated my eclipse
project after I installed the latest wicket snapshot. But I removed the
whole wicket snapshot directory and did a clean checkout, now everything
works. But the issue still remains though. The code looks like this:
public BasePage() {
final WebMarkupContainer table = new WebMarkupContainer(this,
"tableId");
table.setOutputMarkupId(true);
final Label label = new Label(table, "labelId", "This is a label");
label.setOutputMarkupId(true);
label.setVisible(false);
new AjaxFallbackLink(this, "linkId") {
private static final long serialVersionUID =
5523627214368899839L;
@Override
public void onClick(AjaxRequestTarget target) {
final boolean visible = label.isVisible();
label.setVisible(!visible);
target.addComponent(table);
}
};
}
When I click on the AjaxFallbackLink the first time everything is fine, the
label (with wicket id "labelId) gets visible. But when I click the link
again to make it invisible, I get a NullPointerException when executing
label.setVisible(..). Debugging down into the wicket source code tells me
that the NullPointerException occurs on 327 in class Page, when it tries to
execute "versionManager.componentStateChanging(change)". However
versionManager is null. Why is this? Is this a bug or am I doing something
wrong?
Thanks
