What is the correct semantic in this case:
<service name="JVM Definition" singleton="true" createDeletePolicy="both">
I would like to be able to have exactly 1 child resource of that type below a given parent.
In the plugin code, I can of course prevent the creation of a 2nd child by looking at the list of existing children.
It would be good though, if that logic could also run in the server/UI so that the Create Child->JVM Definition would be greyed out if one child is already there.
Also it looks like the "singleton" flag just tells the UI to not put the resource in a folder when there are more than one, but directly below the parent
In the screen shot, both 'bla' and 'default' are such singleton JVM Definitions
