Hi guys,
I have a similar problem that NonCachingImage does not solve. I have
implemented a simple expand/collapse button. I check the rendered page
source in FireFox and image name is always "/img/expand.gif". Here is the
code:
/* advanced search link */
add(new AjaxSubmitLink("advancedSearch") {
private static final long serialVersionUID =
3847759110695405700L;
@Override
protected void onSubmit(AjaxRequestTarget
target, Form<?> form) {
advancedSearch = !advancedSearch;
target.addComponent(findUserAcountForm);
}
}.add(new NonCachingImage("expandCollapse", new
Model<String>() {
private static final long serialVersionUID =
3430522655787763141L;
@Override
public String getObject() {
return advancedSearch ?
"/img/collapse.gif" : "/img/expand.gif";
}
})));
Thanks,
Zhubin
