[OPEN] [#46] TabPanel Firing Error

[softmachine2011]

Hi,

With the latest build (rev. 4359) which includes Ext.JS 4.1.2 I found a new bug.
When you open a tab dinamycally, and close it, if you will open a new tab, or close any existing tab it throws an exception.

TEST CASE


<script type="text/javascript">
function openTab(url) {
if (Ext.isEmpty(url, false)) {
return;
}

var tp = Ext.getCmp("sampleTabPanel");
var tabId = url;
var tab = tp.getComponent(tabId);

if (!tab) {
tab = tp.add({
id: tabId,
iconCls: 'icon-colorwheel',
title: 'My Tab',
closable: true,
closeAction: 'close',
loader: {
url: url,
renderer: 'frame',
noCache: true,
loadMask: {
showMask: true,
msg: 'Loading new tab...'
}
}
});

tp.setActiveTab(tab);

tab.addListener('activate', tab.syncSize);

} else {
tp.setActiveTab(tab);
tab.fireEvent('activate');
Ext.get(tab.tab.el).frame();
}
}
</script>
<ext:Button runat="server" Text="Open Tab" Icon="ColorWheel">
<Listeners>
<Click Handler="openTab('/Area/Sample/Detail');" />
</Listeners>
</ext:Button>
<ext:TabPanel ID="sampleTabPanel" runat="server" />


Steps:
1-Open Tab
2-Close Tab
3-Open Tab (it crashes, it says that firing is undefined)

It is same issue like in the following thread
http://forums.ext.net/showthread.php?21093-V2-1-Desktop-Window-Close-and-Move

Please update from SVN to get temp fix

[softmachine2011]

And when you would release a permanent fix? Because if it is early I could wait.

The problem is related with ExtJS EventManager, we will report the problem (after preparing sample to reproduce)
But i don't thinks that they include own fix prior 4.2

Therefore if you need to use 4.1.2 then please use temp fix or revert to 4.1.1

Ok, with rev 4360 seems to work right but possibly this fix will increase memory leak as I understand.

Thanks for the fix.

No, the issue is not related with memory leaking
Memory leaking is related with iframe using (not iframe events)
