How to prevent duplicate id

[gnagno]

Hi guys,
i'm using ext js 3.4.

I had a problem because I had two objects with the same ID.

Is there something that can check, when i create a new obj, if the id is already present in Ext?

I noticed that in the 4.1 there is it in dev mode. And in 3.4?

Best bet: don't assign static ids. Instead, use the itemId config.

You could use Ext.getCmp() to retrieve any existing component with a provided id.
