hi daniel -
we had exactly the same issue when we first set up ERAttachment. we worked around it by having all of our relationships to the specific subclasses.
i never got time to figure out what it was doing but i'd guess the inheritance is getting mixed up somewhere - it's as if ERAttachment isn't abstract and hence it's trying to fetch an EO with pk = 5 and storageType = "". maybe if you pump out the raw sql in your logs you could post the sql it's actually using to try and fetch the attachment...?

Hi all,
I need some help with ERAttachments. I configured an attachment for an entity as is explained in the Attachment tutorial. Everything goes fine at the beginning, I can add new attachments, display a list with all my attachments, I can logout the application and when I return everything looks Ok. I have checked the table and all looks Ok. for ERAttachment and ErAttachmentData, but if I restart the application I get the following error message:
|
Error: |
java.lang.IllegalStateException: The object with globalID _EOIntegralKeyGlobalID[ERAttachment (java.lang.Integer)5] could not be found in the database. This could be result of a referential integrity problem with the database. An empty fault could not be created because the object's class could not be determined (e.g. the GID is temporary or it is for an abstract entity). |

I changed the relationship to ERDatabaseAttachment and now I can restart the applicaiton aand I get the correct attachment data, but in the tutorial said that the relationship should be made to ERAttachment, what I'm missing?

Daniel.
