Hey, really weird, I use Seam with GlassFish, and GF comes with JSF1.2RI, It seems to be a native JSF error message.. Here's my JSF code: | | <h:selectManyListbox id="setnotes" size="10" value="#{issue.notes}" required="true"> | <f:selectItems value="#{noteListForSelectbox}"/> | <selectitems:convertEntity entityClass="edentity.entity.Note"/> | </h:selectManyListbox> | | <span class="errors"><h:message for="setnotes" showDetail="true"/></span> | | One thing that i'm not sure about, In the html code, I see that the generated selectbox options look like this: | <selectitems:convertEntity entityClass="edentity.entity.Note"></selectitems:convertEntity><select id="j_id37:setnotes" name="j_id37:setnotes" multiple="multiple" size="10"> <option value="edentity.entity.Note@17585e9">Note1</option> | Is this is how it should be? in none-multiple selectbox I see the ID as the value option. thanks a lot.
