Trait input field validation

[confettidc]

Hi,

I would like enhance the text input with "name" attribute value got some restriction.

I create my "input" type as below:

editor.DomComponents.addType('input', {
		// Make the editor understand when to bind `my-input-type`
		isComponent: el => el.tagName === 'INPUT',

		extend: 'input',
		model: {
			// Default properties
			defaults: {
				traits: [
					{
						type: 'text',
						label: 'Name',
						name: 'name',
						required: true
					},
					{
						type: 'select',
						label: 'Type',
						name: 'type',
						options: [
							{id: 'text', name: 'Text'},
							{id: 'number', name: 'Number'},
						]
					},
					'placeholder',
					{
						type: 'checkbox',
						label: 'Required',
						name: 'required'
					}
				]
			},
			// Model definition
			init() {
				this.on('change:attributes:name', this.handleNameChange);
			},
			handleNameChange() {
				var name = this.getAttributes().name;
		    	console.log('Input name changed to: ', name);

		    	if (name == 'name' || name == 'email' || name == 'mobile') {
		    		console.log("here");

		    		//editor.runCommand('core:undo');
		    		const component = editor.getSelected();
		    		component.getTrait('name').set('value', '');
		    		component.getTrait('name').props().value = '';

		    		editor.Modal.open({
						title: 'Error',
						content: name + ' fieldname is forbidden, please add as system field'
					});
		    	}
		    },
		},
		
	});

It successfully removed the "name" value in canvas and display the modal:

However, the value still in trait settings:

How to remove the value in trait also?

Thanks.

The trait reads always the data from the component so you should reupdate it in such a case component.addAttributes({ name: '' })

Yes, this can make the value in canvas disappeared, but the typed value still exists in traits, any method to remove that value? Thanks.

By checking the demo addAttributes triggers also the update of traits. Are you using the latest version?

[confettidc]

Yes, v0.17.29

And trait value only can update when reload page (editor)

Thanks.
