Type defs do not update

[RTSLVU]

I am new to using type defs and was under the inpression that if I updated the type def (add or remove a selection) then the instant of the control all the constants linked to the control and cases would be updated.

This does not seem to be the case. I have to delete and reinsert the control, then find every constant in my diagram and delete and reinsert, and It really meses up the cases. I have to remove all the "red" cases and make sure the are no doubles in my cases.

What am I doing wrong here? Type Defs were suppose to make this eaiser?

They sould and they do!

Please post a zip of a simple VI (along with the type defs) tht you are having trouble with and someone should be able to help out.

Take care,

Ben

Do you have "autoupdate from type definition" checked in the properties? (should be checked by default).

Else can you attach a simple example that shows the problem. What is your LabVIEW version?

[smercurio_fc · Accepted solution]

It sounds like you left the control as a regular "custom control" and did not change it to "typedef".

 

Or, do you keep the control editor window open when you make a change to the typedef? If so, the change won't propagate until you save and close the control editor or select File->Apply Changes (if you want to keep the control editor window open).

As Christian already stated, typedefs should autoupdate. But sometimes, this is not possible. If so, LV marks the "not updated instances" as grayed out. You could right click on them and select "update from type def".

hope this helps,

So now that you brought that up....

I have never encountered such a situation. Can you give us an example of when it is not possible?

Curious,

Here is the type def in question and a simple vi.

and the winner is....

Saverio

See his post above. You aren't saving it as a type def.

E.g the situation Saverio descibed 🙂 That means, if the type def itself is still open and not saved after a change (sometimes happens to me when working with enums).......

[EDIT] But you are correct in a way that "update from type def" is still grayed out......

How about constants?  How do you make a constants that updates with typedefs? 

I have a typedefs cluster which contains components, when I update it all the typedefs in the project update (as expected) but the constants do not.
