Workaround:

Workaround Exists
Workaround Description:
- Use "mvel: className" in defaultHandler field or
- remember to change the resolver for your WIH in kie-deployment-structure.xml
Steps to Reproduce:
Hide

Create a new service repository, for example:

[wsiqueir@wsiqueir repository]$ tree . ├── HelloWorld │ └── HelloWorld.wid └── index.conf 1 directory, 2 files

In HelloWorld.wid, does not specify a resolver in defaultHandler field

Start jBPM pointing to your repository:

./bin/standalone.sh -c standalone-full.xml -Dorg.jbpm.service.repository=file:///opt/repository -Dorg.jbpm.service.servicetasknames=HelloWorld
Show
Create a new service repository, for example: [wsiqueir@wsiqueir repository]$ tree . ├── HelloWorld │ └── HelloWorld.wid └── index.conf 1 directory, 2 files In HelloWorld.wid, does not specify a resolver in defaultHandler field Start jBPM pointing to your repository: ./bin/standalone.sh -c standalone-full.xml -Dorg.jbpm.service.repository=file: ///opt/repository -Dorg.jbpm.service.servicetasknames=HelloWorld

Description

When we set a new local repository and do not provide a resolver in defaultHandler field, it breaks the project build with a NullPointerException exception (see below) The reason is that it will leave the "resolver" dropbox without any value in kie-deployment-descriptor(see attached screenshot).
