Hi,

you can use Display#syncexec() from your non-UI thread. Additionally you
have to inform RAP to listen to UI callbacks using
UICallBackUtil.activateUICallBack( uiCallbackId ) and
UICallBackUtil.deactivateUICallBack( uiCallbackId ) afterwards.

See the RAP widget demo (ProgressbarTab.java) for an example.

Regards,
Stefan.
