strict type def. ring bug?

[Pnt]

I just noticed that the strict type def. of a ring is not updated as i would expect.

I put one instance in front panel and one as a constant in block diagram. If i change the strict type def. only the front panel control is changed.

Shouldn't the block diagram constant be updated too?

(Auto update is on)

You are not alone in your expectations but no that is not a bug, see here.

Unlike the enum data type the strings of a ring are NOT part of the data type and therefore changes to the typedef DO NOT update all instances.

Labview needs one additional type between strict type def and a normal typdef, one which will update the look of all references when the typdef is changed but not strictly enforce the type.  I have this issue often where strict types (like a ring) is unusable (because of the inability to update certain properties like strings[]) but keeping a common look throughout an application.  The only work around for these situations are to update the look of a control typdef, save the typdef as strict, close the typdef, reopen the typdef set it from strict back to a regular typdef then continue programming as usual.  A lot of extra steps just to keep interface consistency.

Thanks guys...

I think NI should change a little, the way a Ring works.

Place this .llb in  ...\National Instruments\LabVIEW xxxx\project\
The next time you run LV, it will show up in the Tools menu.
When you run it, it shows a list of all Ring TypDefs in memory.  You select one, then click OK, and it updates the strings & values all instances of that TypDef that are in memory.

I found a much simpler way to code it.  Here's the new version.
