The Signature widget documentation states that a boolean attribute HasSignature gets set to true when a signature is present. It then states that setting it to false will clear the image. Access to HasSignature in my domain model is Read only and will not let me change it. Also, I see no way to access ‘HasSignature’ in a microflow. Anyone have any ideas or examples? Thank you! Rick
You are probably trying to use one of the already available boolean attributes from the System.Image generalization.
The permissions for these attributes can’t be changed as they are part of the system module that can’t be changed.
Just create your own boolean attribute on the specialization entity and use this to set whether a signature is present or not and this will work like a charm.
