After setting up feed from custom feed, and click the behaviors button, i got this alert error box with the following message

While executing onLoad, the following JavaScript error(s) occurred At line 585 of file "PATH_TO_FILE/Commands:dmxBehaviors.htm" getDocumentDOM: Argument number 1 is invalid

Already clean up dreamweaver CS6 cache, and tried to use another feed source.

Any guess?

Cheers

I know this is a common issue, that is mostly solved by clearing out a cache file. I've done that to no avail. And then discovered that the "DmxBehaviors.htm" file doesn't' even exist. What extension do I need to reinstall in order to restore this file?

Hi Matt,
Please make sure to download and install the latest version of HTML5 Data Bindings.

re-installing HTML5 Data Bindings fixed the issue. Thanks
