Jenkins plugin development - persistence - plugins

Question

I'm still learning plugin dev. This is my first one.
I would like to persist the configuration of my plugin, but it won't work.
Could you please tell me, what am I doing wrong?
I have tried debuging the process, starting from the addition of the plugin to the job 'til the saving of the job config.
I have found, that inside the load() method of the descriptor, no xml file is found!
The path it is looking for is something like: c:\users\Peter\workspace\r-script.\work\whatEverDir\xy.xml
I don't think that the .\ part is causing the config file not to be found, but since it is a Jenkins class generating this path, I would not bet on it. Although the system might have tried to create it here at the first place.
Thanks in advance!

Sorry for the code formatting! First timer at stackoverflow code posting.

I think you may need to comment this line out
#Override
public boolean configure(StaplerRequest req, JSONObject formData) throws FormException {
req.bindJSON(this, formData);
save();
//return super.configure(req,formData);
return true;
}
as it will then save again but with no fields.
