Hello Tommy, rewrite <select t:type="select" t:model="option" t:id="option" t:value="option"> to <select t:type="select" t:id="option">
If you explicitly name a model (t:model="option"), it has to be an implementation of org.apache.tapestry.SelectModel. Your Enum "Option" apparently is not an implementation of that. That causes the exception I think. For Enums it is not necessary to explicitly name a model, because Tapestry auto generates one. So simply leave it out. The t:value is not necessary either, because t:id="option" corresponds to a field with the exact same name in the page class. For an example look at the Enum example at the middle of the page: http://tapestry.apache.org/tapestry5/tapestry-core/ref/org/apache/tapestry/corelib/components/Select.html Regards, nillehammer ----- original Nachricht -------- Betreff: Tapestry 5.0.11 - Selecting elements causes Exception in ValueEncoderSource Gesendet: Fr, 13.
