Hello guys here is the workaround :

Seems like there is a bug in the Jquery library.

Any component that requires some dimensional computation for its initialization won't work in a hidden tab, because the tab panel itself is hidden via
display: none
so that any elements inside won't report their actual width and height (0 in most browsers).

There's an easy workaround. Use the off-left technique for hiding inactive tab panels. E.g. in your style sheet replace the rule for the class selector ".ui-tabs .ui-tabs-hide" with

.ui-tabs .ui-tabs-hide {
    position: absolute;
    left: -10000px;
}

For Google maps you can also resize the map once the tab is displayed like this:

$('#example').bind('tabsshow', function(event, ui) {
    if (ui.panel.id == "map-tab") {
        resizeMap();
    }
});

resizeMap() will call Google Maps' checkResize() on the particular map.
