Validate Text field not empty
I'm using justinmind trial so this may be the case.
I've searched google on how to simply validate a text field if its empty or not.
I have a registration screen with only an email and password text field. Before i insert new data into my datamaster, i have to see if the text fields are not empty.
I've searched and the results are that people use an expression 'regexp' and i don't have that in my constant tab of expressions.
In any case, all i want is to simply check the text fields if they are empty or not.
(I only need to simulate the flow of my project so i don't need to delve too deep into validation, I only need this because i need to simulate a registration function)
