loading mask on a combo box

[Anthony.Hall]

My json store for my combo box is quite large. Occasionally i have to reload the store.

When i reload the store these is no indication to the user that the store is reloading.

What is the best approach to display "loading..."

There should be a loadmask on the drop-down list by default. Are you using 4.1.0, I believe there was a problem with the loadmask not appearing using that version? There's a discussion of how to patch this in the comments for setLoading:
