How to get "comment" from taskoutcomes

Support
#1

Hi, as part of an authorization process using BPM addon,
I need to get the comment entered during the taskoutcome input dialog.

In the setAfterCompleteTaskListener the procActionsFragment.getProcInstance().getProcTasks()
return Null because the task is not committed yet.
Because I get this error :

How can interact with current active ProcTasks in then setAfterCompleteTaskListener lambda listener ?

Hi,
you may try something like this:

        procActionsFragment.initializer()
                .standard()
                .setAfterCompleteTaskListener(() -> {
                    ProcInstance procInstance = procActionsFragment.getProcInstance();
                    List<ProcTask> procTasks = dataManager.load(ProcTask.class)
                            .query("select t from bpm$ProcTask t where t.procInstance = :procInstance")
                            .parameter("procInstance", procInstance)
                            .view(View.LOCAL)
                            .list();
                    for (ProcTask procTask : procTasks) {
                        log.info("ProcTask name: {}, comment: {}", procTask.getName(), procTask.getComment());
                    }
                })
                .init(PROCESS_CODE, getEditedEntity());

Hello,

thank you for your answer,
In my use case, if I try to use this (your) code with the update of the current Entity:

ProcInstance procInstance = procActionsFragment.getProcInstance();
List procTasks = dataManager.load(ProcTask.class)
.query(“select t from bpm$ProcTask t where t.procInstance = :procInstance”)
.parameter(“procInstance”, procInstance)
.view(View.LOCAL)
.list();
for (ProcTask procTask : procTasks) {
getEditedEntity().setAttribute(getEditedEntity().getAttribute().join(" - ", procTask.getComment()));
log.info(“ProcTask name: {}, comment: {}”, procTask.getName(), procTask.getComment());
}

I get the following error:
Exception Description: The object [com.company.workflow.entity.MyEntity-7debd925-cfb7-c5a0-8c63-688222f7469f [detached]] cannot be merged because it has changed or been deleted since it was last read.
because in setAfterCompleteTaskListener the task is not committed yet…

But I tried solved this issue in the bacht-mode in the following way:

   public ProcInstance loadProcInstanceById(UUID id) {
        LoadContext<ProcInstance > lc = LoadContext.create(ProcInstance.class);
       LoadContext.Query query =
               LoadContext.createQuery("select e from bpm$ProcInstance e where e.entity.entityId = :id")
                       .setParameter("id", id) ;
       lc.setQuery(query);
         return (ProcInstance) dataManager.loadList(lc).get(0);
     }

public ProcTask loadProcTaskById(UUID id) {
    LoadContext<ProcTask > lc = LoadContext.create(ProcTask.class);
    LoadContext.Query query =
            LoadContext.createQuery("select e from bpm$ProcTask e where e.procInstance.id = :id")
                    .setParameter("id", id) ;
    lc.setQuery(query);
    return (ProcTask) dataManager.loadList(lc).get(0);
}

the I call theese ones:

ProcTask pt = loadProcTaskById(loadProcInstanceById(a.getUuid()).getId());
