I have been trying to grok this all day and I'm at my wit's end. I feel like I'm missing something really simple. I'm trying to set and access workflow variables from a business rule. Here's what I've done.
I created a test workflow in my personal instance called "Test Workflow". I edited the inputs on that workflow to add a string variable called TestVar [u_testvar], and I set the default value of it to "Init test".
Now I've plopped a Run Script workflow activity in the workflow that accesses this variable and prints it out to the script log. I'm trying to access it by both workflow.variables and workflow.inputs, because to be honest, I'm still not really sure what the difference between those two things are.
Here's my script:
gs.log('--->Access [1]: ' + workflow.variables.u_testvar);
gs.log('--->Access [2]: ' + workflow.inputs.u_testvar);
I fire off the workflow, and in my script log I see:
So far, so good. But let's say that in my script I want to change the value of the variable. I've added some more lines, throwing in the kitchen sink, trying to account for all ways of setting this variable. Now it is as follows:
gs.log('--->Access [1]: ' + workflow.variables.u_testvar);
gs.log('--->Access [2]: ' + workflow.inputs.u_testvar);
workflow.variables.u_testvar = 'Modify Variables Test [1]';
gs.log('--->Access [3]: ' + workflow.variables.u_testvar);
workflow.update();
gs.log('--->Access [4]: ' + workflow.variables.u_testvar);
workflow.inputs.u_testvar = 'Modify Inputs Test [1]';
gs.log('--->Access [5]: ' + workflow.inputs.u_testvar);
workflow.update();
gs.log('--->Access [6]: ' + workflow.inputs.u_testvar);
Again, I fire off the workflow, and this is my script log:
...!!?
Nothing I did in the Run Script activity had any affect on the workflow variable.
Okay, well, let me try finding this thing via a background script, so that I can eventually put it in a business rule.
var grRequest = new GlideRecord('sc_request');
if (!grRequest.get('number', 'REQ0010002'))
gs.print('Cannot find request');
var msg = '--->Looking for workflow variables in ' + grRequest.number + "\n";
msg += ' Using variables: ' + grRequest.variables.u_testvar + "\n";
msg += ' Using inputs: ' + grRequest.inputs.u_testvar + "\n";
gs.log(msg);
From my script log:
Nothing. Nothing I do can seem to access these variables. The best I've been able to achieve so far is reading the default value from inside a script. What gives? How do I set variables in workflow scripts? How can I read and write them from a business rule?
And before you refer me to this article, please understand that I have read it a dozen times. It tells me how to read a variable, but not to write to it, and certainly not how to access it in a business rule. And before you refer me to this article, I've read it a dozen times also. It explains how I can write the variables when I start the workflow from a script, but not after that time.
Help?
Thanks,
