Using JFace dialogs with RAP 2.0 [message #1013819]

Hello,

I am new to RAP but can't find this issue in the forum. I have a class which is an extension of org.eclipse.jface.dialogs.Dialog. When I open the dialog I enter an endless loop with the error that Display.sleep() is not implemented.

I tried using the DialogUtil.open method but it does not take a JFace dialog as a parameter. I've tried a number of other solutions but none work.

Do I have to avoid using JFace with RAP? That would be unfortunate. Any advice will be appreciated.

Thanks in advance.

Hi Michael,
starting with RAP 1.5 the default application operational mode is
JEE_COMPATIBILITY (see [1]). This mode does not support Display#sleep().
In order to use the JFace dialogs with this mode you have to implement
yourself a non-blocking solution similar to DialogUtil#open that handles
JFace dialogs. Another solution is to switch in your application
configuration the operational mode to SWT_COMPATIBILITY (see [2]),
where JFace dialogs will work out of the box.
