[1.0.1a]&[1.1b1] possible form rendering bug

[KRavEN]

I need to be able to add form items to an already rendered form. I've figured out how to do it and have it working but I ran into a behavior that I don't understand.

I have a function that gets called when I click a button. Below I've broken down the function.

First I add a form container


vipStart = form.container({width:410});

2 elements under it:


form.column({width:285},
appVipBox = new Ext.form.TextField({
fieldLabel: 'VIP IP',
name: 'appVIPIp',
width: 100
}));

form.column({width:70, labelWidth:25},
appVipPort = new Ext.form.TextField({
fieldLabel: 'Port',
name: 'appVIPPort',
width:38
}));

and then close the container:


vipEnd = form.end()

I get the already rendered element with:


vipBox = Ext.get(vipBlock.id);

So far so good. Now I render the container. This will create all the divs and the labels but not the inputs.:


vipStart.render(vipBox);

To create the input fields I render the close:


vipEnd.render(vipBox);

Now the problem and possible bug with this is that it ends up rendering any form.button I have to the bottom of the elements I just added. The buttons were added to the form prior to the first render. Should this be happening?

I work around it by rendering the inputs separately instead of rendering vipEnd. This seems like something I would think I shouldn't have to do since just rendering the close does the same thing except it undesirably adds the buttons:


appVipBox.render(vipBox.dom.lastChild.childNodes[0].firstChild.lastChild.id);
appVipPort.render(vipBox.dom.lastChild.childNodes[1].firstChild.lastChild.id);
vipBox.createChild({tag: 'div', cls: 'x-form-clear'});

Any thought on if this is the expected behavior, I'm doing it wrong, or it's a bug?
