OK I couldn't figure out what was wrong so I did it as a last resort:
/* advanced search link */
AjaxSubmitLink advancedSearchLink;
mainTable.add(advancedSearchLink = new AjaxSubmitLink("advancedSearch") {
private static final long serialVersionUID = 4373219220751138123L;
@Override
protected void onSubmit(AjaxRequestTarget target, Form<?> form) {
advancedSearch = !advancedSearch;
target.addComponent(mainTable);
}
});
advancedSearchLink.add(new WebComponent("expand") {
private static final long serialVersionUID = 1566267580506427230L;
@Override
public boolean isVisible() {
return !advancedSearch;
}
});
advancedSearchLink.add(new WebComponent("collapse") {
private static final long serialVersionUID = 4204455496315941511L;
@Override
public boolean isVisible() {
return advancedSearch;
}
});
It's not the best way to go, but it works.
