My team would like to know if it is possible to set the maxLength of the value input of Form Type< Plain Text>, using the expression parameter in the form configuration window (Activiti/Flowable). When we use RegExpression ^[a-z0-9]{1,2}$ and try to execute the workflow it returns the expression in the value field. Use case: The Start user enters in a Tax Category but it must always be 2 characters [a-z][A-Z][0-9] before the form can pass to the next reviewer or be submitted.
