Bug with .setPropertyParameters() for Dropdown Control
This method seems to generate a "Duplicate item names are not allowed" error when using an array where an index is a substring of another index. This example specifically triggers it: ["HeadTop", "Head", "HeadBottom"]; will not be accepted by the method (the "Head" index seems to throw it off) - But: ["HeadTop", "HeadMiddle", "HeadBottom"] will be accepted.
Thanks very much for filing this report. An internal ticket has been filed linked to this issue and the team will be taking a look at it.
