Issue

In LiveCycle ES processes, adding map or list values to maps and lists can cause unexpected behavior.

Solution

LiveCycle ES processes do not support collections of collections; therefore, do not add collection values to other collections.

Additional Information

When adding a collection to another collection, each item in the first collection is added to the second, not the collection itself. For example, a process has a list variable called listVar. The Set Value service adds values to listVar:

/process_data/listVar[1] = "abc"
/process_data/listVar[2] = "xyz"

The Set Value service then adds this list to another list called uberListVar:

/process_data/uberListVar[1] = listVar

The first item in uberListVar is “abc,” and the second item is “xyz.”
