bpm_workflowDueDate

[gslamy]

Hello!

I have some problem with start my task in date from "bpm_workflowDueDate" field.
I tried to get this date from "bpm_workflowDueDate" field:

   <startEvent id="startevent" name="Start" activiti:initiator="initiator" activiti:formKey="scwf:startstaff">  
      <extensionElements>
        <activiti:taskListener event="complete" class="org.alfresco.repo.workflow.activiti.tasklistener.ScriptTaskListener">
          <activiti:field name="script">
            <activiti:string>      
               <![CDATA[execution.setVariable('startdate', task.getVariableLocal('bpm_workflowDueDate'));]]>
            </activiti:string>
          </activiti:field>
        </activiti:taskListener>
      </extensionElements> 
    </startEvent>
‍‍‍‍‍‍‍‍‍‍‍‍‍

Now I want to start next task in this date from variable "startdate-3 days". I tried to add a timer, but I think it has a different date format and doesn't work.

Hi,
could you create a unit test for it?

if you provide such a unit test will be easier for all the community members to understand what are you trying to do (and how); and then will be also easier to help.

I am newbie. I can't do it, but I need in an example how to get duedate and start some task in this date.

If you'll write a unit test there are 90% chances to solve the problem by yourself, and even more, next time you'll know exactly how to write such a unit test. (it's a good exercise)

just put a breakpoint inside the ScriptTaskListener class and inspect the variables and then you'll see exactly what's happening.

for writing the unit test you can follow the steps from this link: http://www.jorambarrez.be/blog/2012/09/24/how-to-write-a-unit-test/

But I don't get errors. I don't know how to calculate number of days from "bpm_workflowDueDate" field (I use Alfresco 5.0.d). I want to run the task in this day. That is, I need to get the number of days and use timer.

[vasile_dirla]

what type is "bpm_workflowDueDate"  variable ?
if it's java.util.Date then you could do it like that: (by using joda time)
<code>
Interval interval = new Interval(oldTime, new Instant());
</code>
or
<code>
int diffInDays = (int)( (newerDate.getTime() - olderDate.getTime())
                 / (1000 * 60 * 60 * 24) )
</code>

if it's a string, then you should convet it to Date first of all.

But how to calculate the number of days?
1. I must get current date.
2. I must get date from Alfresco user task.
3. Calculate number fo days between current date and user task date to get duration (i.e. P10D).

Yes, you ate right these are the steps.
The number of days between 2 dates is the number on milisecconds / milisecconds in a day.
