Start workflow in liferay 7.2
Regular Member Posts: 148 Join Date: 5/1/19 Recent Posts
Hi
I had a workflow module that was working properly on liferay 7.1
But now I created Workspace and Module in accordance with liferay 7.2
When I start workflow according to the code below
WorkflowHandlerRegistryUtil
               .startWorkflowInstance( importation.getCompanyId(), importation.getGroupId(), importation.getUserId(), Importation.class.getName(),
                                       importation.getPrimaryKey(), importation, serviceContext );

                                     
I have encountered the following exception!!!!!

Hi
According to i downloaded Liferay 7.2 and created  Liferay Workspace and modules accordance with liferay 7.2 , do I need a Liferay Upgrade Planner?

Hi Ali,
The upgrade planner will help you to migrate your old Liferay workspace and custom code in 7.1 to 7.2, if you need help on that, use it.
Cheers.

Could you try with the recently released Liferay 7.2 GA 2 (or in case of DXP, upgrade to the most recent patch?).
A Nullpointer Exception in KaleoInstanceTokenModelDocumentContributor was fixed after the release of GA1.
