Dear community,
I have the following problem. I created my model and added all semantic items. Then I added some non-semantic groups and items. When I select model at the WebUI and then check the option to show non-semantic items everything is ok and they are displayed at the tree as long as I will not add the state description metadata to such non-semantic group item. After adding metadata (e.g. State description) item disappears from the tree.
Question is why? How to prevent such behavior. It is very convenient when the whole “logical” structure can be seen on tree. Otherwise such “hidden” items assigned to some parent groups can easily disappear among large numbers of other items.
I am not aware of any solution. An issue is open in github ( see above link ) and as far as I understand as long as it is not closed the problem still exists.
For my specific case in which I wanted to incorporate the value unit in the widgets, I have found another way to do it without having to go through this bug.
My solution is inside a widget to fill the label field with an expression. I attach an example:
