Hi,
For a chat application I would like to display a list of chat requests that
have come in.
This list is updated by making use of an AbstractAjaxTimerBehavior.
When the user clicks a chat request in the list, a popup window will open
containing that particular chat conversation. In FF all works fine.
The unfortunate thing is that whatever I try, in IE7, the window containing
the list will become the active window whenever the timer fires, thus hiding
the popup window.
Even more strange:
- If the popup was started from a static (ie non dynamically updated)
element the popup doesn't lose focus.
- In wicket 1.2.6 it works fine.
I have been trying various approaches, for instance my own little Java
script creating the popup links, but for some reason I just can't get it to
work. I am willing to accept that is another IE7 "feature" , but that
doesn't help me much.
I am not really comfortable with Javascript, so before I dive into the
Javascript differences between Wicket version 1.2.6 and 1.3.x I would like
to ask whether somebody on this list might have some suggestions.
I have attached the Index.html and Index.java for the current 1.3 snapshot.
In 1.2.6 it works (mutatis mutandis).
Regards,
Wilko Hische
