what is you opera version?
could you please visit live demo gmap example. Seems works fine for us.
Thanks for you answer ... I think you got me wrong.
The above mentioned problem (rerender of gmap and/or page) is NOT a browser-specific-problem - it happens in all browsers (tested with firefox, opera 9.52, konqueror, ...).
The initial rendering (when the site is opened for the first time) is displayed and looks ok BUT if I hit a a4j:commandButton or a4j:commandLink it looks like that the whole page is re-rendered (whenever a reRender is configured or not) and the content disappears (blank, white page) ... the browser tries to connect to maps.google.com (statusbar) and i see the sand-clock ...
I know ... the demo-site is working (for me too) ... my site is much bigger and it's quite hard to trigger down the problem (guess I have to exact some parts of it).
Ok.. please paste simplified snippet of the page and java code for button action.
"a4j:include" was causing these problems ...
I've replaced ...
<a4j:include id="gmap_content" viewId="inc/gmap_inc.jsp" />
(which was working on richfaces-3.2.1)
<a4j:outputPanel style="display:block" id="gmap_content"> <%@ include file="inc/gmap_inc.jsp" %> </a4j:outputPanel>
- and it's working fine.
