In working with the workflow tooling, I have generated my own ‘WorkflowUserTask’ entity, which inherits from the System version. When I create my template page for the workflow user tasks and try to call a snippet which has my ‘CustomWorkflowUserTask’ as the context entity, the Mendix modeler is giving me an error saying that I can only call snippets either without a context entity or with the ‘System.WorkflowUserTask’ entity as context.
My ‘CustomWorkflowUserTask’ entity is every bit as good as the ‘System.WorkflowUserTask’ version, and even better for my purpose.
