hi all,
I’m trying to generate formulars using the PropertyItemSet and FieldGroup classes. Some component elements should be set to read-only (ie. a ComboBox with academic degrees) but I don’t get this managed.
I thought I could achive this by using the ObjectProperty.setReadOnly() method but this does not seem to work. It looks like the readOnly state gets lost somewhere during the use of the setPropertyDataSource() or wrapInTransactionalProperty() methods of the FieldGroup class.
I’m using a dataBean with complex Attributes, this attributes are aware of their own readOnly-State.
private FormLayout createPersonalDataForm( PersonalDataBean personalData ) {
FormLayout formLayout = new FormLayout();
ArrayList<KAMAttribute> propertyValues = personalData.getPropertyValues(); // List of bean-attributes
ArrayList<String> propertyCaptions = personalData.getPropertyCaptions(); // List of attribute-captions
PropertysetItem item = new PropertysetItem();
FieldGroup fieldGroup = new FieldGroup(item);
for ( int i = 0; i < propertyValues.size(); i++ ) { // for each attribute element
KAMAttribute attribute = propertyValues.get( i );
String caption = propertyCaptions.get( i );
ObjectProperty<KAMAttribute> objectProperty = new ObjectProperty<KAMAttribute>( attribute ); // build property
objectProperty.setReadOnly( attribute.isReadOnly() ); // set readOnly-state
item.addItemProperty( caption, new ObjectProperty<KAMAttribute>( attribute ) );
Field field = ISUtilsVaadin.generateField( attribute, caption ); // generate suitable component ( with custom converters )
fieldGroup.bind( field, caption ); // bind attribute to component
formLayout.addComponent( field );
} // for
return formLayout;
}Could anyone explain why using the ObjectProperty.setReadonly() method does not work in this case? What am I doing wrong?
Thanks!
