I'm having a strange problem where particular entity changes are not (usually) being reflected on my screens. I start with a vanilla seam-gen application that generates these artifacts:
| DepartmentList.xhtml (main application screen) | DepartmentList.page.xml | ProjectList.xhmtl (List of Projects) | ProjectList.page.xhtml | | Department.java (@Entity) | DepartmentList.java (extends EntityQuery) | DeparmentHome (extends EntityHome) | Project.java (@Entity) | ProjectList.java (extends EntityQuery) | ProjectHome (extends EntityHome) | | | Easiest way to show you where I'm going is to look at a picture of part of the DepartmentList screen: http://sawdust.50webs.com/images/spurs_display.jpg | (No comments on the artwork please--I'm a server-side guy! I'll let the UI pros do what they do best.) | You'll see departments with a sub-listing of projects for ea. dept. | | You see the "tape recorder" buttons? They change the status on Projects (update the entity). When I push these buttons the Project entities actually are correctly persisted to the database but no changes appear on the DisplayList screen. :-( Reloading the screen or visiting most other screens has no effect--the db and the screen are still out-of-sync. | | Here's the weird part: If I first go to the ProjectList.xhtml screen (not touching anything there--just let it render) then immediately go back to DepartmentList.xhtml then click on a tape-recorder button for one click only the on-screen status changes immediately as desired. Subsequent clicks continue to change the persisted Project status but no screen changes occur unless I again visit ProjectList.xhtml. Huh? | | This is hard to diagnose w/o seeing all the code, but I didn't want to dump reams of useless code into the forum. I'll post a chunk of ProjectList.xhtml since there seems to be some "magic" in simply visiting this page. If other files would be helpful let me know and I'll post them. | | When I click a tape-recorder button in DepartmentList.xhtml (<s:link> w/image) I pass the ProjectId as a <f:param>. A stateful session bean does an em.find() on the ProjectId to get the Project entity, simply calls proj.setStatus() and we're done. Nothing fancy. Somewhere, somehow--something in the UI is still holding onto a copy of the previous Project object. | | Thanks in advance for any advice/clues! | Greg | | ProjectList.xhtml | | | <!DOCTYPE composition PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" | | "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";> | | | | <ui:composition xmlns="http://www.w3.org/1999/xhtml"; | | xmlns:s="http://jboss.com/products/seam/taglib"; | | xmlns:ui="http://java.sun.com/jsf/facelets"; | | xmlns:f="http://java.sun.com/jsf/core"; | | xmlns:h="http://java.sun.com/jsf/html"; | | template="layout/template.xhtml"> | | | | <ui:define name="body"> | | | | <h:messages globalOnly="true" styleClass="message" id="globalMessages"/> | | <div class="results" id="projectList"> | | | | <h3>Projects</h3> | | | | <h:outputText value="No project exists" | | rendered="#{empty projectList.resultList}"/> | | | | <h:dataTable id="projectList" | | var="project" | | value="#{projectList.resultList}" | | rendered="#{not empty projectList.resultList}"> | | <h:column> | | <f:facet name="header"> | | <s:link styleClass="columnHeader" | | value="projectId #{projectList.order=='projectId asc' ? messages.down : ( projectList.order=='projectId desc' ? messages.up : '' )}"> | | <f:param name="order" value="#{projectList.order=='projectId asc' ?
