[JBoss Seam] - s:fileUpload when used along with h:selectOneMenu
by james_haysï¼ mac.com
I'm hoping somebody can shed some light on this issue. I've had a frustrating battle with this off and on for a few days now. The issue, it appears, is intermittent. It works sometimes, and others it blows up.
I have a form that has an <h:selectOneMenu and an <s:fileUpload. If I only makes changes to one or the other element, the submit works fine. If I choose an item from the menu AND choose a file, I will sometimes get this stack dump.

Sometimes it works though... Same process to getting to the form. The stack tells me that productRecord is null and can't be outjected. The question is why is it null? It shouldn't be.
Here is the relevant html:
| <h:form enctype="multipart/form-data">
| <table cellpadding="0" cellspacing="2" border="0" style="font-size: 13px">
| <tr>
| <td colspan="2">
| <label>Product Status:</label>
| <h:selectOneMenu id="productStatus" value="#{productRecord.productStatus}">
| <s:selectItems value="#{productManagement.productStatuses}"
| var="productStatus"
| label="#{productStatus.name}" noSelectionLabel="-- None --"/>
| <ec:convertEntity/>
| </h:selectOneMenu>
| </td>
| </tr>
| <tr>
| <td colspan="2"> </td>
| </tr>
| <tr>
| <td colspan="4">
| <rich:togglePanel value="#{productManagement.editMode}" switchType="client"
| id="editToggle" stateOrder="fileMode,locationMode">
| <f:facet name="fileMode">
| <h:panelGroup>
| <table>
| <tr>
| <td style="font-size: 12px" colspan="4">
| <span style="padding-right: 4px"><label>Switch Edit
| Mode:</label></span>
| <rich:toggleControl for="editToggle"
| value="Enter File Location"/>
| <br/><br/>
| </td>
| </tr>
| <tr>
| <td>
| <label for="fileChooser">Choose Your File:</label>
| </td>
| <td colspan="3">
| <s:fileUpload id="file"
| data="#{productManagement.fileData}"
| contentType="#{productManagement.fileContentType}"
| fileName="#{productManagement.fileName}"/>
| </td>
| </tr>
| <tr>
| <td colspan="4">
| <h5>Use the Browse button to upload your document to
| LCGM.</h5>
| </td>
| </tr>
| </table>
| </h:panelGroup>
| </f:facet>
| <f:facet name="locationMode">
| <h:panelGroup>
| <table>
| <tr>
| <td colspan="4" style="font-size: 12px">
| <span style="padding-right: 4px"><label>Switch Edit
| Mode:</label></span>
| <rich:toggleControl for="editToggle"
| value="Upload File to LCGM"/>
| <br/><br/>
| </td>
| </tr>
| <tr>
| <td>
| <label for="fileLocation">Enter File Location:</label>
| </td>
| <td align="left" colspan="3">
| <h:inputText id="fileLocation"
| value="#{productRecord.documentLocation}"
| size="50"/>
| </td>
| </tr>
| <tr>
| <td colspan="4">
| <h5>
| Copy & paste URL or type in the location of the
| document.<br/>
| Note - other users may or may not have access to
| documents on other servers.
| </h5>
| </td>
| </tr>
| </table>
| </h:panelGroup>
| </f:facet>
| </rich:togglePanel>
| </td>
| </tr>
|
| <tr>
| <td colspan="2"> </td>
| </tr>
| <tr>
| <td colspan="2">
| <h:commandButton styleClass="controller"
| action="#{productManagement.saveProductRecord}"
| value="Save Changes"/>
| </td>
| </tr>
| </table>
| </h:form>
|
The page starts with the call of this action:
(this is in a SFSB running inside a conversation)
| @Out @In(required = false)
| private ProductRecord productRecord;
|
| @Begin(join = true)
| public void manageProductRecord(ProductRecord productRecord)
| {
| this.productRecord = productRecord;
| }
|
So, to recap. My page will open fine with the appropriate object. When I click on the "Save Changes" button, is when I get this error. Sometimes...
Any thoughts or suggestions would be greatly appreciated.
Thanks,
James

[Beginners Corner] - Re: invoking an EJB over iiop
by jaikiran
How are you application(s) packaged? Are the EJB jar and the war file, two separate applications or are they part of an ear file?
Also, do have a look at this wiki page (if you havent already seen that ) http://wiki.jboss.org/wiki/Wiki.jsp?page=ClassCastExceptions
Additionally, in your code try using some debug statements like:
// lookup you ejb
| Object obj = ctx.lookup(".....");
| // i guess this is going to output Proxy$ or something similar
| System.out.println("Returned obj is of class: " + obj.getClass());
|
| // now lets see whether we can narrow that object
| if (obj instanceof MyHome ) {
| //where MyHome is the class name of the bean's home
| System.out.println("Everything looks fine. Lets do the PortableRemoteObject.narrow");
| MyHome home = (MyHome) PortableRemoteObject.narrow(obj,MyHome.class);
| System.out.println("Success");
| } else {
| System.out.println("Most probably a classloader issue");
| System.out.println("Object returned was loaded by: " + obj.getClass().getClassLoader());
| System.out.println("MyHome class in the servlet was loaded by: " + MyHome.class.getClassLoader());
| }
|
|
|
|
P.S.: I havent tried this code, you might have to do any changes that are required. But it might just give you some options to try out.

[JBoss Seam] - Seam + Remoting + ajax4jsf question
by viniciuscarvalho
Hello there! I'm trying these combination, and I'm bit confused with the mix, hope someone help me out.
I'm using a Stateful bean that has a property:
| @Stateful
| @Name("userService")
| @Scope(SESSION)
| public class UserServiceBean implements UserSession{
| private User user;
| //this is a webremote method
| public void setUser(int id){
| this.user = em.find....
| }
| public User getUser()
| }
|
So it's a pretty easy simple bean right :)
The user clicks in a event that triggers the SeamRemoting method:
| userService = Seam.Component.getInstance("userService");
| userService.setUser(id);
|
So far so good, method is triggered and user is bound to the bean. So The user clicks on another component that uses ajax4jsf to re-render a panel:
| <img onclick="reDraw()"/>
| <h:form>
| <a4j:jsFunction name="redraw" data="#{userService.user}" reRender="userPanel"/>
| <h:form>
| <rich:panel id="userPanel">
| ... contents
| </rich:panel>
|
Now, what happens is that the getUser returns an empty user (as if it is an new invocation) If I call the set user, then reload the page, the user is still null. Seems that the Stateful bean is not being bound to the same client, ajax calls seems to be a different cllient to the container.
I'm really confused on how to bind the ajax invocations to the stateful bean.
Could someone give me some directions?
Regards
