The concept is simple. You have 2 pages. The one from which you go and
the one which is supposed to follow which is rather slow. The first page
contains a hidden div which gets visible when the user submits the form.
This div is the one which you see with the animated gif. When the slow
page has finished it's load it will replace the first page. This is
based on the fact that the browser will keep the old page until the new
one is loaded.
<input jwcid="@Submit"
listener="ognl:listeners.validateAction"
value="message:validate"
onClick="doWait(this, false);"
/>
The doWait just shows the hidden div/iframe. The only complicated part
was to make the div/iframe about the combo boxes. If this is what you
need I could create a working simple example.
