fieldSourceGrid

[acarur01]

I have a silly question to ask - I have this code in our product but it wasn't documented and now I'm trying to figure out what fieldSourceGrid is and what I could possibly need to check the value of this for. I can't find it in the documentation - I assume because it is a hidden entity, but could you tell me what it is used for? Thanks!

if(this.grid.fieldSourceGrid != null && this.grid.fieldSourceGrid.isA("ListGrid")){
      if(this.valueMap != null)
        return this.valueMap;

"fieldSourceGrid" is an internal detail of certain special ListGrids that share field definitions (like the summary row and filter editor).

We can't really tell what the code you show was intended to do or to work around.
