Have a look at TeamSite::WFworkflow. Things of use to you might be GetTasks() to get a list of all of the tasks owned by the workflow. Also you might use getVariable and setVariable from the same module, to set some value in the previous tasks and get it later.

Hope this helps; if not more information about what you want to achieve would be handy.

Cheers

If you know the name of the previous task you can get its details using GetTaskByName();

Take a look at this post.

hi

thanx for the reply.. i tried this earlier but am getting an array of following output..

%TeamSite::WFtask=HASH(0x19c636c) TeamSite::WFtask=HASH(0x19c63a8) TeamSite::WFtask=HASH(0x19c63e4)
what should i inferr from this.

basically my requirement is to get the previous task name...

hi there

thanx for the suggestion. sorry for furnishing little details with my querry. in my case the transition to my current task is from more than one task... so i don't think getTaskByName() will work.

I think Jeremy might be onto something here.

You've got Task A followed by either Task B1 or Task B2, followed by Task C. In Task C, you want to find out which of Task B1 or Task B2 did stuff. You could use GetTaskByName to get the tasks B1 and B2. I'm guessing here, but if you query them both with GetState you might get something useful. The IWOV documentation for what possible values there are for the state of tasks is lacking, but you might get something out such as "Completed" for one and "Inactive" for the other.

What type of tasks are A, B1, B2 and C in your situation, i.e. externaltasks? usertasks?

hey Lozza!

task A: User task
task B1 and B2: User tasks
Task C : External task

i'll try using GetState.. it would be great if you can send me the syntax for it..

I am trying another thing. I used " iwgetwfobj.exe" CLT with current task id as a parameter and got an XML which shows me the predecessor.
I can parse the file and get my thing working but.. code will be big... i'm working on it though. let's see.

I will surly try ur suggestion...

I think $state = $task->GetState(); is the likely syntax. Even if this idea is utterly wrong do let me know how it goes ;-)

if you do an `iwgetwfobj` on the active external task, there is a node in the XML output called "predecessors"...you want to find the predecessor that has the 'hasactivated' attribute value of true...that gives you the ID number of the predecessor task, and then you can use GetTaskByName to get the name of the predecessor...
