I have a DataTable with a single column. The table has a toolbar assigned
which provides sorting and filtering.
The filtering is done via TextField that has the following
OnChangeAjaxBehavior assigned.
OnChangeAjaxBehavior onChangeAjaxBehavior = new OnChangeAjaxBehavior()
{
@Override
protected void onUpdate(AjaxRequestTarget target)
{
FilteredLazyLoadingDataProvider<T, S> provider =
(FilteredLazyLoadingDataProvider<T, S>)
dataTable.getDataProvider();
provider.filter(FilterAjaxFallbackOrderByBorder.this);
target.add(dataTable);
target.appendJavaScript("moveCaretToEnd(document.getElementById('"
+ m_filter.getMarkupId() + "'))");
}
@Override
protected void updateAjaxAttributes(AjaxRequestAttributes attributes)
{
super.updateAjaxAttributes(attributes);
attributes.setThrottlingSettings(new ThrottlingSettings(id,
Duration.milliseconds(200), true));
}
};
When I view a page in Chrome/Firefox everything works as expected. When I
view the page in Internet Explorer 11 I observer the following issue.
If the filter textfield has focus and is empty, the
OnChangeAjaxBehavior.onUpdate method is continually called (ajax requests
spam the server). As soon as I enter a value into the text field, the
filtering is performed and the ajax calls cease to spam the server.
What is interesting is if I create a simple form with just a textfield in
and assign the above OnChangeAjaxBehaviour, the textfield in the form does
not have the same issue as the one in the table header.
My app is deployed in Tomcat 7.0.30 (although the issue can also been seen
when testing via jetty)
Wicket 6.12
I have created a quickstart that can be run to observe the issue if anyone
is interested (what is the best way to provide it?)
I would appreciate if anyone can give me some pointers as to what is going
on.
