[Flow] Converting Objects by additional identity does not work?

[Christian Loock]

Here is what the documentation of the Identity Annotation states:

Identity<http://docs.typo3.org/flow/TYPO3FlowDocumentation/TheDefinitiveGuide/PartV/AnnotationReference.html#identity>

Marks a property as being *(part of)* the identity of an object.

If multiple properties are annotated as Identity, a compound identity is
created.

For Doctrine a unique key over all involved properties will be created -
thus the limitations of that need to be observed.



Addding another @Identity field will only add it to the primary key. Thusly
Flow cant be able to retrieve an Object by just supplying a part of it.


In you case, I would just add a method to the Repository Class
GetThingyByForeignId to which you supply the foreign ID which will then
return the desired Entity. Your action would then receive the foreign ID as
a string and load the entity with GetThingyByForeignId.
