Handling Identical Enum Items on Multiple Instance (Add Items, Case Structure and Make Type Def)

[PalanivelThiruvenkadam]

Hello LabVIEW Experts.

I am using LV 2017 (Not sure how it works in Recent Versions of LabVIEW). Sorry if its fixed in Recent versions.

Started this thread to share my recent learning/bug.

It all started like this.

One my Engineer was re-architecturing existing LabVIEW Application and it has 40+ States/Cases Defined- Out of which two were identical and he is not able to figure out the duplicate.

We spend sometime to resolve by sorting and finding the duplicate.

Later i was working on the same to figure out why cant LabVIEW Highlight the issue/restrict from adding.

LabVIEW does restricts User from adding identical Items when using Edit Items of Enum Properties.

But it allows me to add identical items when users adds using shortcut/add items.

During this experiment i also found that LabVIEW doesn't allow user to create (Make Type Def) if the items are identical.

The above behavior is perfect but there should be a warning why they are not able to (Make Type Def)

I have Few Points on this.

1. There should be Error Warning/Highlight  to make user to debugg where the identical cases located (helpful when more states are mapped)

2.There should the restriction in adding items at all levels (all possible options to add items)

3.There should be an warning why user cannot (Make Type Def) when there are identical items.
