Valuelist through relation

Hi
In 6.1.2, I use a value list through relation and I have this warning:

Field “fld_familia” has attached a related valuelist “familias” that doesnt have the same datasource as form “{2}”

But it’s correct and works fine

Why this warning?.

Thanks

Juan,

What does relation in value list familias look like?
What is its datasource and what is the datasource of the form fld_familia is placed on?
