(aye pete ;-) ) The following is developed on: JBoss 4.1.2 / Seam 2.0.0.CR2 I have an entity chemical which declares this field: | private Set<Equipment> equipment; | Danger is an enum. I have tried using this in a page with a selectManyCheckbox: | <h:selectManyCheckbox value="#{chemical.equipment}"> | <s:selectItems value="#{enumLists.equipment}" var="item" label="#{item}"/> | <s:convertEnum /> | </h:selectManyCheckbox> | Here enumLists.equipment is an array of the values of the Enum Equipment. However this renders the following issues when submitting the data in this page: | sourceId=j_id19:j_id32[severity=(ERROR 2), summary=(Conversion Error setting value 'PP EP EX TOX' for '#{chemical.equipment}'. ), detail=(Conversion Error setting value 'PP EP EX TOX' for '#{chemical.equipment}'. )] | Some more digging through writing a custom converter, I found out that getAsObject is not being called. However getAsString is. On the net I found a similar issue http://www.icefaces.org/JForum/posts/list/0/3634.page. Reported http://www.jboss.com/index.html?module=bb&op=viewtopic&t=108853 is that it should work. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4100760#...
