(mold stringField) label: 'Firstname:'; on: #propertyValue of: ValueHolder new; beRequired. (mold stringField) label: 'Lastname:'; on: #propertyValue of: ValueHolder new; addCondition: [:input| input size >= 2] labeled: [:input | 'There is no such short name.']; beRequired: 'Lastname required.'. (mold dateField ) label: 'Birth date:'; on: #propertyValue of: ValueHolder new; beRequired. panel := nil. panel := PluggableDialogPanel open: mold label: 'Example One' view: #renderForms accept: [mold validate. panel morphExtent: panel minimumExtent. "I don't like to do it manually" mold isValid ifTrue: [ mold save. panel delete] ]</pre> </td> </tr> </tbody> </table> It is in the Cuis-Smalltalk-UI repo, I also added a PluggableDialogPanel. One point I don't like, not related to the forms, is after each form validation I have to manualy resize the Panel, because depending on error message. See my comment in the code example.
