check for length and if the length is zero, then you can return for a validation message, otherwise return nothing. I hope it helps you

Hi akhikt..

It is usual behaviour at times ... Instead using isnull() you can use APN_isBlank....

Like if ( or (isnull(ri!input), ri!input=""), "Your message" ,{}) ....

Or rule!APN_isBlank(ri!input)

You can try this at times null will not actually captured in isnull() fn!

As Kumaraveln mentioned, using a common text field is one option to display required messages, however a!validationMessage might be another option for editable grids.

As robertp mentioned, you can use requiredMessage if you are in recent version. In our case we use a common text field to display all custom required message when various fields in a grid are left empty.

Hi Akhlit, one quick question. why can't you make the field as required and provide "requiredMessage" with validation message you are looking, than putting a validation rule?

@akhilt: Its an expected behavior. As per documentation validation messages appear only when the component's value is not null. i.e., you can only display custom formatting related error messages. Like characters cannot be greater than 20, special characters not allowed. But if you want custom message to be displayed when field is empty, you have to use a different component to display that message. PFA ..

Hi, I think the problem is that validations for text fields don't validate null values:

"validations : Validation errors to display below the field when the value is not null."

Try using required/required message

Can you double check that the parameter name is spelled correctly in the text field? If "validations" is misspelled or missing the "s" at the end then it will not function correctly.
