Hi,
Sorry, I have to explain detailed, but the situation is not complicated. I
run into a NPE and I'm not sure if it's a wicket or inmethod-grid issue (or
even my fault ;-), so I need your assistance where to fill a issue.
Situation:
I have a page with a inmethod grid. From there I can navigate to a page
containing a edit form. The PageParameters contains a PageReference, so
onSubmit I'm able to response back to the page I came from, like:
setResponsePage(reference.getPage());
This works great when I'm using org.apache.wicket.markup.html.form.Button.
When I'm using AjaxButton instead of Button I'm getting a NPE in
com.inmethod.grid.common.AbstractGrid (line 130, constructor ->
Behavior#afterRender)...
if (getWebRequest().isAjax()) {
AjaxRequestTarget.get().appendJavaScript(getInitializationJavascript());
}
...this, because isAjax() is true, but AjaxRequestTarget.get() is null.
Something I figure out: When I use setResponsePage to a new version (instead
of using Page from PageManager) like:
Page page = reference.getPage();
setResponsePage(page.getClass(), page.getPageParameter()) ;
...isAjax() returns false, so NPE happens only when I use Page from
PageManager (and I have to).
So the question is:
It's wrong that isAjax() returns true in case of Page from PageManager
...or...
is the if-statement of inmethod AbstractGrid wrong?
Any help would be appreciated.
regards
minas.
If you want I can upload a minimal project to reproduce.
