Re: set table disabled while ajax request is running
You can use AjaxChannel with the same name for all Ajax buttons/links in

Re: set table disabled while ajax request is running
The easiest way to do that is to use
http://ci.apache.org/projects/wicket/apidocs/6.x/org/apache/wicket/ajax/IAjaxIndicatorAware.html
See
http://wicketinaction.com/2008/12/preventing-double-ajax-requests-in-3-lines-of-code/
for
an example.

Re: set table disabled while ajax request is running
Hi,
You may show a veil above the table to prevent clicking on elements during
the ajax call
