In Conditional Expressions:
How is it possible to check, if a variable is empty?
Example WHEN (variableName = Empty). In Java, Empty would mean null.
Create a condition that is When... [variable] = [double click and leave this space empty]
You have to build the condition WHEN (variable=Empty) and the Empty is the Aaa item inside the Constants tab in the Expression Builder
Thanks! That works!
I need to do the same check, but for a file upload within a Data Grid. Is there a way to check if a file upload is empty or not? I've tried "", null, empty, " ", 0, Count=0, etc. and nothing seems to work. Thanks.
