How to switch off validation of a field using guidebridge?

In an adaptive form I want to hide fields that are not relevant anymore because of values in other fields.

Example: In the country I live children have a legal representative until they're grown up. If on a form somebody enters a birth date which indicates that he's older than 18 years the field demanding the name of his legal representative becomes obsolete. Such a feature is what I understand by adaptive form!

The only way I've found so far to accomplish this is :

* do not use the mandatory flag (because a field is always mandatory even if it's not visible)

* check in field's validation expression whether it is visible at all: if it is visible check its value else validation expression returns true

What I would like is a way to switch validation off by guidebridge in a elementVisibleChanged event. Is this possible? (The guidebridge documentation is deceptively incomplete for such questions.)

Thank you,

Urs Hofmänner

Hi 

You can use the validationsDisabled property of a Field to switch off validations. In your example, you can write in the value commit expression of the birthdate field 
 

if ( checkIsabove18 ) { // replace checkIsAbove18 with an actual check
    legalRepresentation.visible = false; // assuming the name of the legal representation field is legalRepresentation. If not change this with the actual name
    legalRepresentation.validationsDisabled = true;
} else {
   legalRepresentation.visible = true;
   legalRepresentation.validationsDisabled = false;
}

Hopefully it solves your problem.

Happy to Help

Hi Varun 

thanks a lot for your response.

I didn't know the field's validationsDisabled property.

I'm using in a generic way:

window.addEventListener("bridgeInitializeStart", function(event) { var gb = event.detail.guideBridge; gb.connect(function() { gb.on('elementVisibleChanged', function(event, data) { var widget = guideBridge .resolveNode(data.jsonModel.target.somExpression); if (widget.className == 'guidePanel' || widget.className == 'guideTextDraw') { return undefined; } if (data.jsonModel.newText) { widget.validationsDisabled = false; } else { widget.validationsDisabled = true; } }); }); });

With this code I can enable/disable validation depending on its visibility.

Regards,

Urs

Hi Urs,


May I know how you are hiding the field ? Are you using the Visible Expression or the Value Commit Expression. In your use case using Value Commit Expression will give better performance.
