Loading non-grid componet with dynamic URI

In ExtJS 3.2.1, the following code was working:

textArea.el.load(aURL); this loads the content of text area from the URL provided.

The same code does not work in ExtJS 4.2.1, also I tried in different ways using bodyEl.el.load(URL), nothing works.

Looked around so many ExtJS books, blogs, google and unable to find the equivalent code to make this work in ExtJS4.2.1.

Could someone please help me here?

Thanks
