Workflow model, how to end the workflow

Hi,

I am using worklow model 10.0.0.1, TS 6.7.1 SP1.
I have created a workflow model and initiating after selecting a DCR.
I need to validate if the user has not attached more than one DCR and if the selected DCR is not already attached with a workflow. To do these validations I am planning to use preprocess JAVA command.

I have 2 questions:
How do I get if the selected DCR is not already in some other workflow in the JAVA class using modeler workflow API

How do i end the job if the user has selected more than one DCR or the DCR is already in some different workflow after showing a error message to the user.
This needs to be done in preprocess JAVA class.

Following is the sample of what I have created to check if user has selected more than one DCR but I am not sure how to end the workflow if the count is more than 1.

public class PangeaWorkflowModel implements InProcessJavaCommand {
public WFMWorkflow execute(WFMWorkflow workflow, Map params){
// Add a file to the workflow
WFMTask[] tasks=workflow.getTasks();
WFMFile [] wfmFiles = workflow.getFiles();
for (int i = 0; i < wfmFiles.length; i++){
if(wfmFiles.length > 1){
System.out.println("More Than One files are attached.");
System.exit(1);
}
}
// Add a file to the workflow
WFMFile file=new WFMFile("/default/main/baseline/Region/WORKAREA/working/templatedata/hotel/hotel_information/data/UK/ALGHI/Test.dcr","Comment Sample");
try {
workflow.addFile(file);
} catch (WFMException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return workflow;
}
}

Dolly, Nice information for most of the Devnet readers. It would be great if you can share the source of this information with us.

Hi,

This information is present in workflow model user guide 1.0.0.1
Can anyone in this group please help me with the queries I have. I am sure someone must have used workflow model and figured out how it can provide at least some basic checks.

Before a job is created i want to verify two things:
1. If a user has selected more than one DCR (can be checked using preprocess JAVA class)
2. If the selected DCR is already in someother workflow.(can be checked by calling a perl script from JAVA class)

But after verifying these how do I show an error to the user that there is something wrong and stop the job being created.

These are every basic validations but even after trying hard I could not figure out a way to show any message to the user.

I request the techies in the group to please throw some light.

I haven't done much with WFM yet (I still do mostly "old-school" work) - but I believe you should be able to do this with a custom instantiation form using a FormAPI callServer script in much the way you would with a FormsPublisher DCT.

Thanks a bunch for the reply.

Yes. I did try that and I am able to make changes in the custom instantiation DCT and print some alert messages.

So now if i would do my 2 validations (check only one DCR is attached and DCR not already attached in some other workflow) I would need to have selected DCR path in the JS function of the custom DCT. Not sure how this would be available, tried if the workflow modeler global variable is present in JS but it seems they arent.

Second thing is call server is asynchronous call and it does not return any value so how do I know if the validation was successful. Becuase it is asyn call how do i make sure process halts till call server finishes the job.

You make sure the same way you would do so in FormsPublisher - which is have the callServer script reference a callBack routine to indicate success / failure / whatever.
