how to prevent duplicate external references

[veldew]

Hello,

External references are frequently created in duplicate.

Mega only checks if the name already exists when creating one, would it be possible to do a check if the url already exists when creating a new ext ref, and ifso, how should it be implemented ?

kr,

Hi Wim,

For this kind of a thing, if I were you I will use the Repository Consistency functionality and a dedicated MetaTest that is attached to the MetaClass External Reference. The MetaTest would be attached to a macro that is comparing the current path with all the pathes of other external references with a boolean status according to the result. It can be a quite long process for thousands of objects indeed...    

Another solution is to change the metamodel and the type of the metaAttribute on the metaclass External references :

Set the _AtIndex =Unique on Access Path ...
