exception in logger

[Pieter Martin]

Hi,

I am trying to get my blueprints based application to work on orientdb
and am getting the following exception.

It happens on setting a property value to a fully qualified java class name.

Thanks

I see this is happening because my labels contains "::"
I am using UML qualified names for labels, i.e.
"org::this::that::SpecialClass::propertyName"

Is this legal?

Thanks
Pieter

Hi Peter,

Thank you that you provided additional information.

In order to optimize query performance OrientDB creates separate class for each label so for labels you should you the same naming conventions as for class names (the same as in Java actually).
