Hello,

In my application, I have a large number of fieldsets with a lots of form components in them. I keep them all collapsed and expand them when needed. They take some time in expanding because items present in them are xtypes. I want to apply some loading mask on fieldsets so that it may appear during that time. Can anyone kindly tell me how to do it? or is it possible?

Regards,
Saba!

No, this is not possible, because rendering components completely occupies the current thread, so the mask would only become visible after the fields had all rendered.

Is there any other solution? so that the user could know that something is loading...

Yes, but that requires a bit more coding.

Your fieldsets would have to be initially empty and you would have to add the content on expand.

In richfaces we have a <ajax: status> which shows in every ajax call and tells the user that something is happening in the background. So is it possible to show such status in extjs as well?

Yes, but rendering components isn't an Ajax call (during an Ajax call the current thread is idle, but while rendering components it is fully occupied).
