integrating webapp changes into 3.1a1

[kukeltje]

Hi,

I'm integrating my webapp enhancements into 3.1a1. this is comming along nice, but when I try to deploy my own process from the gpd to 3.1a1, I get the following error:

I'm kind of stuck now testing things. Is it because it is an alpha version? Or can there be any other cause?

did you change the hibernate mapping files ?

seems as if you changed the field access from field to property. meaning that your stacktrace indicates that hibernate is using a getter where i would expect that hibernate should use direct field access...

let me know how it goes.

regards, tom.

[kukeltje]

afaik, no changes in the hibernate config. To make sure I'll compare with the version in cvs.

Now I think of it, there is neither a property called event, nor a getter/setter with that name. I'll look further in this direction

There is more with this ProcessDefinition. A clean checkout of 3.1a1 (or head) gives me the following error when just logging in.

ok, there is definately something wrong with how the db is populated with the websale example from the ant tasks. If I leave it out, the ui works and I can even deploy my own process from the gpd (the initial report in this topic).

There is no difference whether I build from within eclipse or from the commandline. Both jdk1.4.2_08 and 1.5.0 give the same result.
