problem in a 3 steps workflow

Hi,

Here a description of a workflow for mutualisation for some kind of files from a branch to another :
1. Main workflow (thougth a wft file) get the files et the attached files from the source branch
2. These files are filtered by an intermadiate nested workflow (mutualise_setup_IntermediateNestedWF.ipl / nested.template.intermediate.xml)
the .ipl configure the three tasks (dummytask, externaltask and wftask) in the .xml model to instanciate a jobfile for the wftask
3. The third step of this workflow has to be implemented in : mutualise_setup_ChildNestedWF.ipl / nested.template.child.xml

Here the question :
* The wft file define a start task which is an "externaltask" and the "nested.template.intermediate.xml" define the dummytask as the start task, then why this following error occur ?
ERROR : 02429 : task is not a start task
ERROR : Could not add files to task newsnot
ERROR : ERROR : 02429 : task is not a start task

* Why the workflow don't reach the "...ChildNestedWF.ipl" called in "nested.template.intermediate.xml" ?

Do someone have any suggestion ?

Thanks in advanced.

You can only add files to the start task.. So, remove <files/> Tag from your XML's non-starting Tasks even though it is an empty TAG that does not really indicate any Files

Dummytasks do not have areavpath nor files sub-elements and therefore are poor choices to use for start tasks which assume that files can be associated with them.

Instead - create a simple no-op externaltask for your nested workflows - the script need do nothing except be callable - no callback to the workflow is necessary, just use a timeout element on the task definition like you would for the dummytask to transition it to the next task that you want to follow it.

About < files / > TAG : files are adding by the PERL code in SCH_mutualise_setup_IntermediateNestedWF.ipl (line #451) by this instruction :

$externaltaskFilesElement->appendChild($fileNodeForExternalTask);

So... I have changed the XML model but the task don't reach neither the "...ChildNestedWF.ipl"

The intermadiate script give the result in qr8aYYrMs3_SCH_mutualisation.wft._job_file_name_20080317.184818_tmp.xml.txt

You are, I assuming, trying to "pass" files from the parent workflow to the child workflow - yes?

As I said before - but I'll try to make it a bit clearer: YOU CANNOT USE A DUMMYTASK AS A START TASK in your child workflow - which the code you posted clearly shows you are trying to do.

Since your dummytask has a timeout of "+000000" it's not being used for anything - why not just get rid of it and make "newsnot" the start task? That should probably fix the problem.

The problem is resolved : The workflow reach the SCH_mutualise_setup_ChildNestedWF.ipl...

You can see the result in attached files...

Thanks for your help !
