How to concatenate strings in Task Events?

Gerardo_Lisboa · August 14, 2011, 9:40pm

The documentation example does not work

webMethods BPM Task Development Help Version8.2:

For example, the following action expression updates the name of the task and some task
business data, followed by an action to apply the changes.
#&#123;currentTask.taskInfo.name} = "Order Number: " + #&#123;currentTask.taskData.order.orderNumber}; 

What is the correct code for this?

Is the solution creating an action on the task which binds the interested values on to a local variable, does the change and binds that back to the intended place?

Thank You.

I can reproduce the same problem. I’ll have the documentation updated. In the meantime you can use a simple java function to generate the correct string.


public String generateName() throws Exception &#123;
		String number = resolveExpression("#&#123;currentTask.taskData.orderNumber}").toString();
		return "Order Number: " + number;
	}

Then in your assignment action you can select the binding expression for that java function. In my project, it was something like: #{DataManipRuleContext.generateName}

Hope this helps.
