Stacks and Container in containers warning [message #1814335]

Hello All,

I'm new to Sirius v6.1.1 and I'm trying to set a diagram organized with several levels of containers in stacks but when I'm validating the diagram, I have a warning :
"
The mapping container1 is defined as a Region Container (ie children presentation set to horizontal stack or vertical stack). It is also itself defined as a Region (ie contained in a Region Container), this could lead to unexpected empty area in the region layout.
"

I'm attempting to create one main container with 2 sub-containers in vertical stack and again the first sub-container has 3 containers in horizontal stack.

Why do I have this warning ?

How can I remove this ?

Thank you

Hi Matthieu,

You might find the following note in the Sirius Specifier documentation for containers:
Quote:

The capability to define complex or recursive stack of regions mixing both stack directions has been introduced in Sirius 3.1.0 as an experimental configuration. Some layout-related actions might produce unexpected result. The limitations only concerns the visual aspects, there is no risk of corrupting the underlying models

The structure you are trying to built belongs to those kind of "complex or recursive stacks of regions", you might encounter some layout glitches or inconsistent behavior while manually resizing the different compartments (the actions have an impact on the parents and sibling compartments). Note that the should work fine but there can be some remaining unexpected behaviors, that's why we still have this validation rule.

This capability has been introduced in Sirius 3.1 and documented as experimental (in Sirius 3.0, the VSM editor was more strict and it was just not possible to try those structures).

Regards,

Maxime

Thank you for your reply.

This is a pity, on my side, "complex stacks" (with 3 levels) is currently manageable and working properly. But I can stay with a warning in the model.

Maybe, this could be part of next improvements...
