Central build fails when checking in an activity

19 Views

I have a web dynpro application that uses a javabean as model. The javabean has several properties that are of type collection that are mapped to DTOs that consist of simple types. I had to add a new simple type (integer) to one of the DTOs and made the same change in web dynpro by adding the integer property to the appropriate model class.

I did a reload + rebuild in web dynpro, dragged the new model attribute from the model to the component controller and added the attribute to my view. I then did a DC build and then a DC deploy and the application works. I can retrieve, update and add values from the database with the new field.

When I go to check my activity in, the central build fails and the failure is related to the new attribute that was added. Im wondering in the problem is related to problems with the NWDI server, as it was restarted several times this week while I had my activity open.

When I browse to the dev/inactive branch in the DTR, I can see the new attribute that was added to JobPartDTO.java class in the DTO DC and I can see the new attribute that was added to the JobPartDTO.wdmodelclass in the web dynpro DC. In the dev/active branch, theses changes are not present.

Here are the errors from the CBS log.
