Work with validation
ShowTable of Contents

Use your own validation tests


Create a Expression Validator and use JavaScript for comparing stuff. The value of the fields is stored in the variable "value". 

value == sessionScope.get("comparevalue");


Here the validator is true if the value of the fields is the same than the value of "comparevalue" in the sessionScope.

Note: if you have a radio button group, you need the validator only in the first field of the group.

Check if one date is greate as the other


var start = value;
var end = getComponent("D_END").getValue();
if (!start) return false;
if (!end) return false;
var dStart:NotesDateTime = session.createDateTime(start);
var dEnd:NotesDateTime = session.createDateTime(end);


return (dEnd.timeDifference(dStart) > 0 )





Check if a value is a mail address

Use a constraints validator with this regex:

^s*[w-+_]+(.[w-+_]+)*@[w-+_]+.[w-+_]+(.[w-+_]+)*s*$





Run validation only on a button click

Standard validators are running on each (full / partial) update, which can be very annoying. 
IBM is aware of that problem in 851 and is working on a general solution.

In the meantime, Tommy Valand developed a good workaround. Click here to see Tommy's solution
