I am trying to do a simple Business Object\*\* Instantiate With\*\* from a service task as a test.

This is the Script Im using create a new ErrorDetail object and return it back to the business variable.

`
import com.company.model.ErrorDetail;
ErrorDetail newDetail = new com.company.model.ErrorDetail();
newDetail.setAcid(1234);
newDetail.setTmsecid(22)
newDetail.setTmcode(“tmcode”)
newDetail.setTimestmp(new Date());
newDetail.setErrorseverity(4);
newDetail.setErrormsg(“hello”)
newDetail.setSource(“source”)
newDetail.setBpstatus(0);
return newDetail;
`

I get a hibernate error.

Is it actually possible to do this? I know you can set the default value and also set attributes from Contracts, but can you instantiate a new BO from within a script?

Has anyone gotten this to work in V7?

Thanks

Hi,

yes, you can.  
You should prefer to use ErrorDetailDAO.newInstance() instead of using the emptyu constructor.

Which error do you have?  
Are you sure that you don’t forget to set a mandatory field?  
Are you sure that there isn’t a “complex” atttributes?

Regards,
