PVMT "null" string diagram styler

Capella
1

Hi,

I just started to use the PVMT add-on and would like to highlight all elements which do not have a value yet for a specific property of type string. If I simply add a String Style with Comparator to “=” and leave the Value field empty, it doesn’t work. Neither if I use ““. Ideally it would capture both null strings as well as empty strings.

Thanks,
Sebastiaan

Interesting.

I don’t have all the details but I am not sure that the “PVMT highlighting capabilities” were designed for highlighting “null/empty string” values but rather highlighting things depending on actual values. Maybe there is a way to make it work, but given your feedback, I doubt it.

Probably the easiest way to do it is to write a Python4Capella script to detect that.

Another other option could be to contract with Obeo so that they develop what’s needed to make it work as you want in PVMT.

Hi Stephane,

Thanks for the answer. I wouldn’t mind to set default values (e.g., undefined). However, if I set such default value in my Configuration PV and I create a new (in scope) object, it doesn’t get this default value. Instead the property remains empty (both for string type as well as enumeration). Am I missing something?

Moreover, it would be nice if it’s possible to “push” the default value to any existing item which doesn’t have a value yet for that property. Based on some examples I found, I managed to use P4C to set the values anyway, but it feels a bit cumbersome.
