I seem to have a problem with the default value in one of my colums by the calculator expression.
I have two specific columns that have widget input one being tekst value and the other being numbers
These are called PlotL and PlotC. At the end there is third column which will have a new value which just is the merging of two value's in those two columns.
So I have made the expression PlotL || PlotC as the "default value" of that Third Column. And the example does give the result what I want. But here is the kicker, after the object is added/Created and I open the Attribute Table, it is still NULL. Now I have searched before here for a simular question and that sollution was just to save my edits and go out of my edits. But after that still nothing.
What is going on here and what I am doing wrong?
