I have a workflow with a complex type attribute, default value was null for the attribute, I want to run a script task to print current workflow token's attribute values by invoking method WorkflowToken.getAttributes(). Don't say to bind attribute with input/output parameter of script task than use the attribute directly, My objective is to create a generic action to do that thing. My script is:
var token = workflow;
System.debug(token);
if(token == null)
{ throw "No workflow token found";
}
System.debug("startDate: " + token.startDate);
var attributes = token.getAttributes();
if(attributes == null || attributes.keys.length == 0)
{
throw "No attribute found for current workflow.";
}
System.debug("found " + attributes.keys.length + " attributes from current workflow.");
var keys = attributes.keys;
for (var i in keys) {
var curKey = keys[i]; var curValue = attributes.get(curKey); System.debug("attribute key: " + curKey + " attribute value: " + curValue);
} System.debug("attribute key: " + curKey + " attribute value: " + curValue);
}
When I don't set value for the complex type attribute.
I could retrieve the attributes and get and null value of the complex type attribute.
But once I set value of the complex attribute.
I got error when running the script task.
I have tried many kinds of complex type, still get same error,I suspect if there's defect on vRO to retrieve complex type attributes from workflow token, or is there anything I missed? Can someone help me?
