Show Array of data in Workflow

dranakan

Hello,

I want to add some data during a Workflow. I would to be able to show an array and the user can add values.
For example, during a step in a workflow a page will be displayed the array. The user can add val1, val2, val3, val4 and other lines…

Workflow X
…
| Data1 | Data2 |
———————
|  val1 | val2 |
|  val3 | val4 |
|  …  |  … |
…
[NEXT]
‍‍‍‍‍‍‍‍‍‍‍

I think that I have to :

1. Add in a model the data . Data1 (type any) and Data2 (type any)
2. Create a form control (like in alfresco/site-webscripts/org/alfresco/components/form/controls)
3. Create the worfklow
4. In the share-config-custom.xml, add the step of the workflow (<config evaluator="task-type"…) and add a field with the template (<control template="…)

Has someone a sample ?

Hello Dranakan,
I think this could help you a little with the data model of the workflow

Thank you albertocursack, I will analyse this !

The code of alfresco-share-datatable-property-type is working 🙂
However I get problem to use it in a workflow form. I had to make some change to run the js code.
The table is displayed on the page during the JS script (I have add some alert("…") instead of breakpoints… but the table cleared after the JS script… So the table is not displayed during the workflow…

I have done some changes :
1. Put the window.onload at the end
2. Replace in the init the DTP.drawDatatable(YAHOO.lang.trim(this.jsonProp.value)); by DTP.drawDatatable(""); (for the moment I just want to show the table…)

The table is diplayed and cleared after the message "end init".

What do I change to use it in my workflow form ?

Thank you

dranakan

The problem comes from the jsonProp which is null ..
Firebug

this.jsonProp is null
[Stopper sur une erreur] var YUIDom=YAHOO.util.Dom,YUIEvent=YAH…lass(a,b)}else{YUIDom.addClass(a,b)}};
alfresco-min.js (ligne 295)‍‍‍

JsonProp at this point is null… (fieldHtmlId is setted). (From the jsscript, in the init)

…
this.jsonProp = YAHOO.util.Dom.get(fieldHtmlId);
…
‍‍‍‍‍

If I try to get from the document… it's also nulll

var tt = document.getElementById(fieldHtmlId);

The window.onload is used to call the code… why the YAHOO.util.Dom.get(fieldHtmlId) don't get the value ?

dranakan

Why YAHOO.util.Dom.get("${fieldHtmlId}") when the js code is call from a workflow form ?

All is good if the form is called during the workflow (<config evaluator="task-type")
I think there is a bug with the start of the workflow… the js is not working correctly : https://issues.alfresco.com/jira/browse/ALF-11899

albertocursack

Hi dranakan,
        Sorry I didn't see your response before, Glad to hear you found useful the datatable, I've founded really useful too.
       I didn't know that the built-in evaluators string-compare and task-type could make the difference…
       I am also trying something similar like you, add a datatable to a workflow form…

        In my workflow model I have a taks that are assigned to a user. If the task implicates differents steps, the user could divide the work and assign it to others user. In order to manage this subtasks within a task, I though I could define a workflow with 0..n sub workflows. Another approach I though, it could be using the datatable as a subtask list and inviting the others users to the task, making let them know what to do with the help of the subtask datatable in the form (this mean having only one workflow)

For the first one, one example could be:

                        Task Name: Make Proposal
                         Assigned to: Peter

                        Then Peter could divide this task in small task (new workflows), i.e.:

                                Subtask Name: Build Procurement Plan
                                Assigned to: Kate
                                Due Date: 12/12
                                Status: closed

                                Subtask Name: Write proposal, attach procurement plan, budget and send it
                                Assigned to: Mark
                                Due Date: 13/12
                                Status: closed

Like I said, I was thinkig to simplify this approach by having the datatable in the workflow form, making the task for multiple users, inviting to the same workflow others (multiple users assigned), and tell them what to do and due date through the datatable…

Which one you think it will fit better, or do you think there is a better approach to do this…

Thanks, Alberto

Hi Albert,

Your users could perhaps be the best help to choose. You should do two POC and ask some users to try.
Don't forget thinking if you need to look at the history of the workflow(s)(which solution is the best to see what has been done).

Best regards.
