ax 2012 - Prevent wrong enum value in a form

(0) ShareShare

Posted on by 1,085

Hi, i have a combobox in a form with three values, say "one","two","three".

I do a check on inventtable to find if the value i'm setting is ok for that item.

How do i take back the combobox to the original value once the user has selected the wrong one?

I dont know where is the right point to put the code.

Thank you in advance

regards

    If you're doing validation on a persisted field, you should be doing it inside the validateField(validateFieldValue in AX2012) method on the table, which is a method called by the AX framework.

    If so, returning false for failed validation is all you need to do, and the AX framework will change the value back to the original value.

    In your case, if the enum is a field on inventTable, modify the inventTable.validatefield method, should be the only thing you need to do.
