Well, my issue is using the invalidate() method so I think I better rewrite my program.
Thanks for adding Icon attribute to Gmarker. Here is simple code that show invalidate issue. Adding, changing, and removing icon are all working fine except for wind.invalidate(). So, I will just rewrite my program and not to use invalidate().

Note: in my gmaps, I use TestGmap class to test invalidate()

public void onCreate() {
Gmarker marker = new Gmarker();
marker.setId("mymarker");
marker.setLat(40.71213418976525f);
marker.setLng(-73.96785736083984f);
marker.setIconImage("http://www.google.com/mapfiles/markerA.png");
marker.setParent(this);
}

Do not put <script> inside your invalidated window. Move it to the main page and specify it ONLY once.
I tried following (move script out the invalidated window) and it works.

<zk>
<script src="http://maps.google.com/maps?file=api&v=2&key==ABQIAAAAmGxmY
R57XDAbAumS9tV5fxTwM0brOpm-All5BF6PoaKBxRWWERSynObNOWSyMNmLGAMZAO1WkDUubA"
type="text/javascript">
</script>
<zscript>
void invalidate() {
mainWin.invalidate();
}
</zscript>
<window id="mainWin" style="margin: 0 auto;" width="800px"
xmlns:h="http://www.w3.org/1999/xhtml">
<gmaps id="mymap" width="600px" height="360px" use="TestGmap"
lat="40.71213418976525" lng="-73.96785736083984" zoom="15" >
</gmaps>

<button label="invalidate GMAP" onClick="invalidate()"/> </window> </zk>

I used your script but why when I added or inserted this statement in my TestGmap
onCreate() method
System.out.println("use onCreate()" + new java.util.Date()) -- the message never show when I press my invalidate GMAP button. The only time it printed the message is during the opening of page. Is invalidate() will never again use the onCreate() method when I moved it to main page?


Thanks,
Narge

invalidate() has the browser to redraw the component's visual parts per the component's object part only. The object part in server is not touched at all.
