No, I wouldn't try changing the transient nature. It does seem kinda odd, though. I know that I'm saving serialized objects two different ways -- by individual DataObject for one read-only context, and by DataContext for a modified set of objects. I don't think I have seen this particular problem.
Are you serializing the DataContext directly? On 9/11/06, Dave Dombrosky <[EMAIL PROTECTED]> wrote:
I downloaded the 1.2.1 source and added some code to figure out what is going on. It appears that context.getChannel() from ObjectStore.java line 945 is returning null. I am guessing that this is because of DataContext line 182 which declares the channel to be transient. Transient properties are not serialized, which is how tomcat saves the session, so it is reverting back to it's default value (null). I tried removing the "transient" part of the variable declaration, but then Tomcat complains on a different piece of code. I'm not even sure if that's the best way to fix it so I don't think I'll explore that any further yet. Is this issue something that I should add to JIRA? -Dave On 9/11/06, Mike Kienenberger <[EMAIL PROTECTED]> wrote: > My suggestion would be to look at the 1.2.1 source and see what's > going on at ObjectStore.java, line 945. > > On 9/11/06, Dave Dombrosky <[EMAIL PROTECTED]> wrote: > > Problem still occurs on 1.2.1 > > > > On 9/11/06, Mike Kienenberger <[EMAIL PROTECTED]> wrote: > > > Maybe http://issues.apache.org/cayenne/browse/CAY-614 ? > > > > > > This was fixed for 1.2.1.
