It didn't have nothing to do with the layer status.  The problem was that when a
user zoom in it triggered a MAP_EXTENT_CHANGED event.  clickUpdateMap() was
called before ScaleWMapExtentsChanged() that updates the scale value (scale
widget).  The following test which verified that the actual map scale was not
the same as the scale displayed by the scale widget was always true. 
clickUpdateMap() triggered MAP_EXTENT_CHANGED event again and again.  Also
UPDATE_MAP was set when a user pressed a key for the UpdateMap widget to detect
a scale change and was not reset.

I removed the scale test and reset UPDATE_MAP after ZoomToScale function call.


if( ({$this->mszHTMLForm}.UPDATE_MAP.value == "1") && (goCWCJSAPI.oMap.scale !=
{$this->mszHTMLForm}.SCALE.value) )
{
    goCWCJSAPI.oMap.oApplication.ZoomToScale({$this->mszHTMLForm}.SCALE.value);
}
