Object Guard : Occurrence of link already exists.

[SVanSchoonlandt]

Hi all,

the user is trying to create a UML state diagram and creates a transition between two state objects. When he tries to attach a guard to it, a script error occurs

Script error "Error(0x800ac3eb) : Object Guard : Occurrence of link already exists." at Line 13 :
 UML Guard Creation : Object Creation Error

Any ideas? We have different environments and it only appears in one of them, they all have the same metamodel though. When I tried to connect a guard to the transition via the explorer, it does not allow me to do it either. It does not give an error message than though but just nothing happens.

thanks

after investigation the issue is due to inconsistency of customer Data on the table MEGAEAWORK.Z1_P_A_METAATTRIBUTE.

This kind of issue should be analyzed on a  case per case basis

In this case an inconsistency of customer data is the cause of the error and the solution was to delete two records.

it seem to be related to the oracle database, in the error log I find the following info

ORA-00001: unique constraint (MEGAEAWORK.Z1_PI_F31401AD5084654F) violated
