Hi Marchal:
By the exception you gave, I presume you are using WebUtil and that module
currently I am not using it.
However doing a quick review in the burrow source I found the following code
in "EntityLoader.GetId" (Wich is called in your stack trace):
public object GetId(object o)
{
if (o == null)
{
return null;
}
PropertyInfo pi = null;
try {
pi = o.GetType().GetProperty("Id");
}
catch ( AmbiguousMatchException e) {
}
if (pi != null)
{
return pi.GetValue(o, null);
}
else
{
return GetSession(o.GetType()).GetIdentifier(o);
}
}
So, I'm totally agree with you, apparently the code to find out the
identifier first try to find a property called "Id", if this is not found
take the current ISession to take that information. Unfortunately it uses
the statement: "GetSession(o.GetType())" to retrieve the ISession, so it may
be other Session than you are using...
My advice: You can:
A - Submit a JIRA ticket with that issue and wait for corrections
B - Include in your entities a property "Id" (It is just a guess I don't
know if it can works)
C - Try to fix yourself the code ( I suggested modify the
statement GetSession(o.GetType()) to other similar to your DAO does)
I expected this can help!
