[r4842] CommandColumn/ComponentColumn are not destroyed correctly

[Yannis]

Hi,

I'm using the Ext.Net 2.1 version.
I have this problem concerning CommandColumn.

Without changing version, have you got a work around to destroy correctly a CommandColumn?

Thanks.

To complete the previous behavior, I tried with Ext.Net 2.3.1 : it is the same thing.

In fact, I try to destroy a window that contains some tabs.
When I load the window, I only see the first tab.
I close the window and I have the error "this.grid is undefined" : line 17373 (debug mode)

If I open each tabs before closing the window, I don't have the error.
One of the hidden tab contains a grid with a command column.

have I forgotten something?

Thanks.

Thanks, it is fixed already, you can use the following override to fix it

Ext.grid.column.CommandColumn.override({
      destroy : function () {        var me = this,
            view = this.grid.getView();


        Ext.each(this.sharedMenus || [], function (menu) {
            if (menu) {
                menu.destroy();
            }
        });
        delete this.shareMenus;
        
        this.removeToolbars();


        if (this.overToolbar) {
            this.overToolbar.destroy();
            delete this.overToolbar;
        }


        if (me.commands) {
            if (me.overOnly) {
                me.view.un("beforerefresh", me.moveToolbar, me);
                me.view.un("beforeitemupdate", me.moveToolbar, me);
                me.view.un("beforeitemremove", me.moveToolbar, me);                
                me.view.un("itemmouseenter", me.onItemMouseEnter, me);
                me.view.un("itemmouseleave", me.onItemMouseLeave, me);
            } else {
                me.view.un("beforerefresh", me.removeToolbars, me);
                me.view.un("refresh", me.insertToolbars, me);
                me.view.un("beforeitemupdate", me.removeToolbar, me);
                me.view.un("beforeitemremove", me.removeToolbar, me);
                me.view.un("itemadd", me.itemAdded, me);
                me.view.un("itemupdate", me.itemUpdated, me);
            }
        }
        
        if (me.groupCommands) {            
            me.view.un("beforerefresh", me.removeToolbars, this);
            me.view.un("refresh", me.insertGroupToolbars, this);                
            me.mun(me.grid, "resize", me.onGridResize, me);            
            me.view.un('groupclick', me.groupToolbarClick);                      
        }


        if (me.grid.isTree || me.grid.ownerLockable && me.grid.ownerLockable.isTree) {
            me.grid.un("beforeitemcollapse", me.removeNodeToolbars, me._cnrScope);
            me.grid.un("beforeitemmove", me.removeNodeToolbars, me._crScope);
        }


        this.callParent(arguments);
    }
});

Hi Vlad,

Ok, in my case, this code does not resolved my problem.
In fact, the Grid Panel that contains the CommandColumn is in a Panel into a tab.
While I don't click on the tab = don't display the content of this tab (the grid and so on) I have an error if I close the window.
The error raises on the line 3 :
view = this.grid.getView
==> because grid is undefined

If I click on the tab to display its content, I can close the window because at this time : this.grid exists.

Do you see what is my problem?
Is there any work around?

Thanks.
