See stacktrace - The customer can't edit a table.
Both Play SQL and Bob Swift's add-on have a class named DynamicTableManager. Depending on the order in which the plugins are loaded, Confluence provides the wrong class to one plugin or another.
The technical solution was to add the following annotation whenever DynamicTableManager was injected:
Play SQL Base 2.11.0-c.jar: This is the same as 2.11.0 with the correction for this problem.
It will also be included in the next version after 2.11.4.
