on Jan 31, 2015Hey.
I'm facing with this weird behaviour trying to re-configure a running workflow's priority
My workflow is created with the default priority, medium.
On the first task user has the option to change the task.priority, and on the complete listener, I use this code to reflect the task's priority change to the workflow's priority:
If I log the those variables' values, I see this:
task.priority = 1
bpm_workflowPriority = 1.0
If for any reason I try to execute that task again, and if the user changes the priority again, lets say, to 3, when I try to reflect the change back to the workflow, I get the error:
The reason I found is on the first execution, since the first value saved at the bpm_workflowPriority was 1.0, a double, when I try to set the new task.priority to it, 3, it fails trying to set the new integer value to the double variable.
This, for me, can be considered a bug, since I seems to be impossible to achieve what I need.
I'm running this test on Alfresco Community 4.2.f.
I've just raised a issue for this error with the same description at https://issues.alfresco.com/jira/browse/ALF-21252
EDIT:
One more info I've just found:
Looking at the database table, I see the register bellow, what confirms my suspect that the value is save as double, even though I set it using an integer
Thank you in advance.

| 19678 | 1 | double | bpm_workflowPriority | 19601 | 19601 | NULL | NULL | 3 | NULL | NULL | NULL |Thank you in advance.
This is the way I did it:
I made a global variable (e.g. customPriority) and in each task I am setting this one, not the bpm_workflowPriority. Then I read it and set the
task.priority.So the workflow priority stays the same, but I change each task priority according to the customPriority value.Not the best way to do it, but it works for me...
