I have a numeric textbox with a SQL query binding on the float property. I have the fallback value selected with a value of 0.
When the value in the database does not exist the query returns NULL, but Ignition gives me a red box around my component.
If I am in the designer I receive the error message:
[quote]Exception: Conversion error: query returned null, binding needs “float”
on query binding for “SPCIR.Root Container.txtXUSL.floatValue”
