When trying to configure a new action that has a condition of a specific host group, the input box is readonly, requiring the use of the "Select" popup. The popup opens as expected, however when clicking on a host group name within the popup I get a javascript error and the group name is not sent back to the action conditions.

The error is "Uncaught Syntax error, unrecognized expression: [name=action.edit]"

This also appears to affect any use of the Select popup (i.e. Template selection)
