    In a workflow task for an entity I want to throw a custom message in the UI whenever the task is approved.

    In the workflow action dropdown the assignee will have 2 options - 'Approve' and 'Reject'. On clicking the 'Approve' I want to show some custom message in the UI to the assignee. Can we achieve this in the custom workflow ? Any help will be appreciated.

    Hi,

    AFAIR this is not possible currently, but if you can share your use case I can probably guide you on how to achieve something similar.

    Hi Snehil,

    We have custom workflow (not DCR) where a user task has 2 options Approve and Reject. Now if the assignee Approves the task then we need to validate if certain field are populated or not (attribute at the entity level). If the attribute is not populated then the workflow should not proceed to the next step and an error message (custom message) needs to be shown in the UI providing the reason as to why the workflow has not proceeded to the next step.

    Now we are not finding any way forward to show this custom message from the validation task. Please suggest what is the recommended approach to show a message in the UI from the workflow service task.

    Thanks.

    hello

    you can customize your business process in the following way:

    • implement your custom WorkflowAction and attach it to a service task right after the user's task;
    • the service task throws an exception if the action was executed without having proper justification (no comments, missing entity attribute, etc).

    The snippet for a custom WorkflowAction

    import com.reltio.workflow.api.WorkflowService;
import com.reltio.workflow.api.actions.Execution;
import com.reltio.workflow.api.actions.WorkflowAction;
import com.reltio.workflow.api.processes.Comment;
import com.reltio.workflow.api.processes.ProcessesService;
import com.reltio.workflow.api.rest.ReltioException;

import java.util.List;

public class ApplyAction implements WorkflowAction {

    @WorkflowService
    ProcessesService processesService;

    @Override
    public void execute(Execution execution) throws ReltioException {
        List<Comment> comments = processesService.getComments(execution.getId());
        // do not allow execute action if there are no comments posted for the process
        if (comments.isEmpty()) {
            throw new ReltioException("{\"responseCode\":400,\"errorMessage\":\"Apply action cannot be executed on a task without comments\"}");
        }
    }
}

    And map this class to a service task

    Then if there was Approve action executed on the DCR Review users' task and execution comes to this service task the following error will be displayed in Inbox:
