I have several property groups registered and working well. I am now trying to add a few more but the Register property Group button doesn't seem to do anything because when I try to use one of the new entries I get a message saying that property group is not registered. I don't see any mistakes in the xml file so just not sure what steps to take to sort this out.
In the Administration metadata, you have two buttons. One named edit ( what allows to change the definition ) and another named ( register ) what applies the changes. Ensure you have clicked on them.
Finally check in catalina.log file for error while editing or registering the changes. If it is shown some error share here.
