The model is a simple Address class with 3 instance variables: street, postCode and town. I have added the Magritte description methods like so: magritteDescriptionPostCode <magritteDescription> ^ MAStringDescription new accessor: #postCode; label: 'Postcode'; priority: 250; yourself The form is a subclass of WAComponent. It has the following method: renderContentOn: html ( Address new asComponent addValidatedForm: { #save -> 'Save'. #cancel -> 'Cancel' }; yourself ) renderContentOn: html The form displays in the browser but has no Save / Cancel buttons and the form tags are missing as well. What am I missing? Thanks for your help. _______________________________________________ Magritte, Pier and Related Tools ... https://www.iam.unibe.ch/mailman/listinfo/smallwiki
