Can't see subprocess variables in multiinstance subprocess

Question

Hello.
I'm trying to generate a multiinstance parallel subprocess, but when i create it i can't see the following variables:
- loopCounter
- numberOfActivities
- numberOfCompletedInstances
- numberOfInstances
- numberOfTerminatedInstances
This variables where created automatically in 11.1.1.3 when you created the subprocess as multiinstance, now i´m using 11.1.1.4 and no one of this variables is created.
Please, any help with the topic would be appreciated.
Thanks in advance.

This may not be much help for your 11.1.1.4 issue, but here's how I worked around the problem with the "loopCounter" variable not always being present in 11.1.15 when using subprocess activity with "MultiInstance" selected. I believe there are two bugs that these steps might help you work around.
Oracle BPM's subprocess activity can have two different loop properties. This means that based on an incoming array of information, work item instances are created for each item in the array.
Double click anywhere in the subprocess's grey background to bring up its properties. Click the Loop Characteristics tab.
If you want to simultaneously generate instances based on each item in incoming array, click the MultiInstance radio button. For the "Loop Characteristics" section in the dialog, set this to iterate through each item in the array coming into the subprocess. For example you might have a variable called "parts" that is the array. Use the count( ) method to determine the number of items in the array.
The "Completion Condition" portion of this dialog determines how many separate instances will be spawned by this subprocess. On the left side of the less than sign, use the loopCounter variable that is automatically created when the "MulitInstance" property was selected. On the right side of the less than sign, insert the same count( ) method you used int he "Loop Characteristics" section. This means that this subprocess will continue creating instances until the last item in the array has been hit.
Click the Arguments tab. In theory, you would think that only the item in the array being iterated through would need to be sent into the subprocess as an argument. The problem is that the "loopCounter" variable is not available to be used here. There is a bug that you have to work around. If you click on the "Use Associations" radio button and click the Edit button, in theory you should be able to build an expression that uses the "loopCounter" variable here to just pass a single object into the subprocess. There is a bug that prevents "loopCounter" from appearing when building the expression. As a result, work around the bug by passing in the entire array into the subprocess as an argument.
Add a Script activity in the subprocess to extract the individual item in the array. Use the "loopCounter" in this to set a single item in the array to used by the subprocess.
For this to work, there is one more work around that you have to do. Add a timer activity just before the Script activity you just added. Set the timer to wait one second. This means that a new instance will be created every second until all the items in the array have been run. If you do not add this timer activity, the same instance is created in the subprocess even though you think the loopCounter is iterating through the array. This means that if you do not add this timer activity, if the array has "Supervisor", "Manager", "Shipping Clerk" then all three individual work item instances spawned will all be created for the "Shipping Clerk".
