| [Texo] Annotation of EReference with no cascades [message #1699432] |

Hi,
I want to annotate an EReference such that no cascades are generated.
I have a class with a reference to itself. When an instance refers to itself (via some other instance), this results in an exception when merge() on the same instance is applied twice.
This happens because the generated JPA code for the class has the cascade.merge (amongst others) annotation for the EReference.
So, I want to remove this JPA annotation, preferably by an texo annotation model.
Here is what I did:
in the annotation model:
- added annotation for the EReference
- added an ORM annotation
- added a many-to-many annotation
- added cascade type annotation
- added empty type cascade annotation
However the annotation editor returns then with following error:
An error has occurred. See error log for more details.
The string resource '_UI_cascadeDetach' could not be located
The resulting annotation looks as follows:
<eReferenceAnnotations xsi:type="ormannotations:EReferenceORMAnnotation">
<manyToMany>
<cascade>
<cascadeDetach/>
</cascade>
</manyToMany>
</eReferenceAnnotations>
Generation of JPA classes also results in an error.
Help is appreciated.
Cur

Hi Cur,
Hmm I missed your post. In any case I published a new build just now which should solve this problem. Let me know if it
stills occurs.

Hi Cur,
A mistake, I published a new build which solves this. The detach cascade type was not handled correctly. I solved this
also. If you don't want cascade you should create a cascadetype node without cascades inside it.
