Hi,
what you're obviously doing is de-couple the view from the model. If
your large number of maps are all using the same context model, you do
not need a sync button at all -- they will automatically synchronize:
<Context id="yourContext">
<widgets>
<MapPaneOL id="map1">
...
</MapPaneOL>
<MapPaneOL id="map2">
...
</MapPaneOL>
<MapPaneOL id="map3">
...
</MapPaneOL>
</widgets>
</Context>
Regards,
Andreas.
