[Lizmap] QGIS expressions question

[Etienne Trimaille]

Hi,

Yes, there is partial support.

It's for creation only, not for editing an existing feature for sure.
Then, it depends of the expression it self : if a previous field is
involved or not, if the geometry is involved or not etc.
It's indeed missing which use cases are supported.
