Hello Develoopers,
I have only one question about this. Why are the fields object.owner and
insrel.dir persistent and not system?
I am trying to make a distinction in my code which fields can be written
by a user and which ones not. I didn't have problems in previous
releases of mmbase, because I excluded all the object and insrel fields,
but now with the new datatype features this is not enough.
org.mmbase.bridge.BridgeException: You cannot change the field lastmodifier
at
org.mmbase.datatypes.processors.LastModifier.process(LastModifier.java:35)
at
org.mmbase.datatypes.BasicDataType.process(BasicDataType.java:476)
at
org.mmbase.bridge.implementation.BasicNode.setStringValue(BasicNode.java:519)
I thought to do it by checking if the field is system managed, but then
the above mentioned fields are an exception on that rule.
Can I just change these field definitions to state="system"?
Nico
Ps it might be nice to have methods in the bridge like
boolean isSystem();
boolean isVirtual();
boolean isPersistent();
boolean isStored(); (isSystem() || isPersistent())
instead of checking the getState() == STATE_*
