[jboss-user] [JBoss Seam] - Re: selectOneMenu and commandButton conflict
"petemuir" wrote : #{application.name} references a String, you are trying to
set it with a Application object. Likewise for language. Read up on JSF converters and
what they do. And take a look at the EntityConverter on the wiki as it does what you are
trying to do for you...
hi again,
for background i read JSF converters,
then i go to wiki for SeamEntityConverter
(http://wiki.jboss.org/wiki/Wiki.jsp?page=SeamEntityConverter)
i download zip file ant tryed to understand.
after all i deside to do my job.
1.i added xmlns:ec="http://jboss.com/products/seam/entityconverter/taglib" into
my facelet. and change selectonemenu component tag like this :
| <s:decorate>
| <h:selectOneMenu
styleClass="font_style" value="#{application.name}">
| <s:selectItems
value="#{applications.resultList}" var="name"
label="#{application.name}"/>
| <ec:convertEntity
entityClass="com.magti.seam.beans.billAdmin.Application"/>
| </h:selectOneMenu>
| </s:decorate>
|
2. i modifyed my component.xml file :
| <framework:entity-query name="applications" ejbql="select a from
Application a" />
| <framework:entity-home name="applicationHome"
entity-class="com.magti.seam.beans.billAdmin.Application"/>
| <factory name="application"
value="#{applicationHome.instance}" />
|
3. i put entityconverter.jar file into my WEB-INF/lib.
but page did not load :
| Value is no String (class=com.magti.seam.beans.billAdmin.Application,
value=com.magti.seam.beans.billAdmin.Application[applicationId=4]) and component
_id17:_id26with path: {Component-Path : [Class: javax.faces.component.UIViewRoot,ViewId:
/login.xhtml][Class: javax.faces.component.html.HtmlForm,Id: _id17][Class:
org.jboss.seam.ui.UIDecorate,Id: _id25][Class:
javax.faces.component.html.HtmlSelectOneMenu,Id: _id26]} does not have a Converter
