"bad type, not parameterized" when storing a self-defined object #244

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What version are you using? (Morphia/Driver/MongoDB)
morphia-0.99.jar,  Driver mongo-2.5.jar,  MongoDB 1.6.3

I tried to store Jimmy Lin's HMapSIWSoft class for Hadoop (extended from 
HMapKISoft class and MapKISoft interface) to MongoDB using Morphia. I think the 
problem is related to the specific java class because I have tried other typed 
primitive classes (Vector, Array) and there was no error. The self-defined 
class is StemProb.java. The executable class is TestMapping.java. 

The reproduced error is as follows:

I've also created a simple test application illustrating the problem: 
https://github.com/xeraa/morphia-errors
As soon as I'm using "@Reference protected List<TEmployee> subordinate;" I'm 
running into this stackdump.

Is there any timeline for this issue? We'd really require it... Thanks!

I was also seeing this error, don't know if it helps anyone else but in my case 
it was because the pojo I was attempting to store extended another class that 
was much more complex. As soon as I remove my pojo from the parent everything 
was nifty.

I just encountered this by calling with datastore.save with the wrong 
parameters. I am just learning the syntax and called: 

MyClass mc = new MyClass();
datastore.save(MyClass.class, mc);

It choked on mapping some feature of the Class object, changing it to 
ds.save(mc) obviously worked.
