What is the best way to determine the length of an array which is a member of a dictionary?
The length(array) or count(array) functions are frequently used to determine the length of an array or list of values. But if the array is a member of a dictionary, these functions always return a length of one.
This test code illustrates the issue:
a!localVariables( local!list: { "A", "B", "C" }, local!emptyList: { }, local!nestedList: { list: { "A", "B", "C" } }, local!emptyNestedList: { list: { } }, { "list" : { list: local!list, length: length(local!list), count: max(a!forEach(local!list, fv!itemCount)) }, "emptyList" : { list: local!emptyList, length: length(local!emptyList), count: max(a!forEach(local!emptyList, fv!itemCount)) }, "nestedList" : { list: local!nestedList.list, length: length(local!nestedList.list), count: max(a!forEach(local!nestedList.list, fv!itemCount)) }, "emptyNestedList" : { list: local!emptyNestedList.list, length: length(local!emptyNestedList.list), count: max(a!forEach(local!emptyNestedList.list, fv!itemCount)) } } )
Test results:
