Compatibility with Config Manager

Hello,
We are using Config Manager to deploy our JIRA customization from an instance to the other. We recently upgraded Xporter from version 6.1.6 to version 6.2.4 and Config Manager is not working anymore.
We did some tests with the other vendor and that's how we discovered your plugin was the cause. If we disable XPorter, Config Manager is working. If we downgrade to 6.1.6, it is working as well.
It seems that you made some kind of customizations on the standard AUI progress bar and changed your API.
When CMJ invokes the progress bar's API it throws an error. See below.

Please help us with this compatibility, this is important for us. If needed, here is the contact from the other vendor support@botronsoft.com (ticket on their side is PS-2907)
