[rules-users] Check a set of objects for a value?

[Patrick]

Hello,

This is my current drool rule:

rule "RULE1"
	when
		context : StaticTaskContext(
			taskToPerform.name == "TRANSFER",
			deallocatedOrder == true,
			currentTask != null
		)
	then
		context.setRuleResult("STAYPUT");
end

What I need to do is check to see if the predecessor task is of a certain
value.

ie:
currentTask.getPredecessorTaskChains().iterate().next().getPredecessorTask.getTaskType()
==  "VALUE"

The predecessorTaskChain is declared as:
private Set<TaskChain> predecessorTaskChains;

How can I go through all the task chains on the current task?

Thanks
