I’m getting the following diagnostic error while saving the resource via

Diagnosis of{ hibernate://?dsname=yigal_db&query1=
from Window where entityname='WINTST2'#Window|id=95}

The ID '35' of
' mpl @e6529c{hibernate://?dsname=yigal_db&query1=
from Window where entityname='WINTST2'#EntityDescription|id=35}'
collides with that of
' yImpl@d9783e{hibernate://?dsname=yigal_db&query1=
from Window where entityname='WINTST2'#ToolResourceRegistry|id=35}'

It seems that there is a conflict between IDs on different classes that
are different tables.

I do not understand why all of a sudden I have ID conflict? (we did
convert a different data set to see this issue, it does not happen with
the dataset from Assembly test).

If I have Window class that has an attribute called “WinIdKey” and it is
marked in the eCore as ID=true.

The Window class references two other classes:
1. ToolResourceRegistry (trrIdKey attribute with ID=true) and
2. EntityDescription (descIdKey attribute with ID=true)
all the ID attributes have a different name.

Why is there a conflict?
