Break the fetch's callback

[ssousa]

Hi,

I have a ListGrid, and during the fetch this list is destroy. So when the fetch's callback is launched, I have a error "layout is null".

Can I break the fetch's callback execution before launching?

I thank you beforehand.

No - its invalid to destroy a component in the middle of a network operation you asked it to perform, because it needs to do cleanup when the response is received. If you don't wa t it visible, just hide() it and destroy it when the network operation completes.
