Hi, this should be a quick answer, but what version of Dojo is being used in Mendix5. If I query dojo.version the version of dojo is the same as the Modeler's version, 5.0.0-beta7. I assume this is the Mendix- and not the Dojo version?
From the release notes of beta6:
Upgraded to Dojo 1.8.
As beta7 does not have a mention of the dojo version, one must asume that the version is still 1.8.
