LVOOP. Problems creating accessor methods

[labviewette]

Dear community,

I have a parent class in which I want to create a reading accessor method for the class data. This works fine for some class data (for example a string) and for others it does not (for example a 2D- String Array). In this case I get a broken wire and the error "Bibliothek die das VI entällt, hat dessen Ausführung blockiert". My best translation for the german error description is: "Library blocked vi execution".

The question is: why?

Please note: LVOOP newbee.

Any chance you added the 2D array, then did not close, and then tried the action?

In that case, at least perform a "apply changes", or close and save the class...

It wouldn't have anything to do with the data (it shouldn't), but with the ordering of your actions.

EDIT: If the class (library) is really locked, you can click it in the project explorer, and select "why is library locked". Often the feedback isn't all that, but worth a try.

Not at all.

If I have the accessor method as a public class method things are fine. When I move that same VI into the properties definition folder i get a broken arrow.

Try autogenerating the accessor. It's probably a connector pane issue.

Right click the class in the project explorer, New -> VI for Data Member Access, then make sure to check the box to let it use property nodes.

Just ruling out the obvious. You did mention your a newbee .

Sorry for the late reply.

It seems that the cause of my problem has been that I was inserting the VI for Data Member Access not in its right properties definition folder.

Lets say I create two data memeber access VIs:

Accessor for A

Accessor for B.

In my understanding it is not possible to move Accessor B into the properties definition folder called "A".
