Show and hide Tabs in TabPanel error

[slonati_adv]

Hi,
I have a error when I try to show/hide Tabs in TabPanel via code.
I have a panel on the left and I want that when I expand or collapse his item the Tabs in TabPanel show/hide.
The solution work if I define the panel as:

<ext:Panel id="Test" Title="Test" runat="server" Border="false" BodyPadding="6" Icon="User" Closable="true" CloseAction="Hide" />

but work only a few times and then crash if I define the panel as:

<ext:Panel id="Test" Title="Test" runat="server" Border="false" BodyPadding="6" Icon="User" Closable="true" CloseAction="Hide">
                            <Loader mode="Frame" ID="LoaderConfigUsersTest" runat="server" Url="Configurations/ConfigUsers.aspx">
                                <LoadMask ShowMask="true" />
                        </Loader>
</ext:Panel>

In the second case i receive the JS error:
"Ext is not defined"

Here is my complete code:

I cannot reproduce the issue with latest code. Try to retest after 2.1 release
