How to stop (cancel) 'deactivate' event on a TabPanelItem ?

[olivierGimenez]

Hi guys !

I need to stop the propagation of the events if a condition is not satisfied when a tabPanelItem is deactivated.
I use this code :

tab.on('deactivate', function(tabPanel, tabPanelItem) {
if (!wizard2view.saveCurrentPropertiesGroup(tabPanelItem.id, null)) {
  // Cancel the event propagation
}
}); 

But, as I read it in the documentation, the event is not given as parameter to the function that handles the "deactivate" action. So I can not code something like that

e.cancel = true; 

So, how can I do ?? I'm really lost ...

Thanx.

I've tryed that but it was not a success :

                                    tab.on('deactivate', function(tabPanel, tabPanelItem) {
                                        if (!wizard2view.saveCurrentPropertiesGroup(tabPanelItem.id, null)) {
                                            return false;
                                        }
                                    });

I've found a solution. Instead of catching the 'deactivate' event on the tabPanelItem, I've coded that :

                wizard2view.jtabs.on('beforetabchange', function (tabPanel, e, tabPanelItem) {
                    if (tabPanel.getActiveTab() && tabPanel.getActiveTab().id != 'treeContentPanel') {
                        if (!wizard2view.saveCurrentPropertiesGroup(tabPanel.getActiveTab().id, null)) {
                            e.cancel = true;
                        }                    
                    }
                }); 

where wizard2view.jtabs is a TabPanel.

The model event is strange on this point, i guess.

Thanx guys.
