[rules-users] process-designer deserialization error

[Antoine Toulme]

The Process Designer is being developed here:
http://github.com/intalio/process-designer<https://github.com/intalio/process-designer>

We fixed the loading issue and it should work on Firefox and Safari as well
as on Chrome, even the beta dev.

We are working on implementing Chrome Frame support for IE right now.

Feel free to take it for a spin.

Thanks,

Antoine
