Did you check if MemberBean class is registered as bean with name "MemberBean" (and not for example as "memberBean");

Not a Valid Method Expression

Are conditionals allowed in action attributes?
I have the following in a navigationMenuItem tag:
action='#{userPasswordChangeBB.setupUser ? "" : "PASSWORD_CHANGE"}'
The error I get is:
Not a Valid Method Expression: #{userPasswordChangeBB.setupUser ? "" : "PASSWORD_CHANGE"}
setupUser calls a method isSetupUser() that returns a boolean.
Any help would be appreciated.
Thanks.

Is this a runtime error or just a validation error coming from an IDE you're using? If the first, please mention which JSF implementation/version you're using. If the second, just configure the IDE preferences to make it a warning rather than an error.

Perhaps you should contact the iTunes store via expresslane. They can look at your account and provide the information you are looking for.
Expresslane.apple.com / select iTunes / iTunes Store / Purchases, Billing and Redemption / then unable to purchase from the iTunes store.
Try the article, and if that doesn't solve the issue, you can Email them, or there may be other options depending on when you access the page, and where you are located.

Error Installing SQL Server Express 2008: '' is not a valid login or you do not have permission.

I have tried installing SQL Server 2008 multiple times on my machine, and I always receive this error about 3/4 of the way through: '' is not a valid login or you do not have permission.
I have tried installing both SQL Server Express 2008 with Tools and SQL Server Express 2008 with Advanced Services, and they both fail the same way. I am trying to do a new stand-alone installation.
I'm running Windows XP Home Edition SP3.
Looking into the error, some forums say I have to install it from THE Administrator account, and not an account with administrator permissions; it also cannot be in Safe Mode, because then the Windows Installer won't work. Unfortunately, I haven't been able to login to the Administrator account. I can go to the home login screen, do ctrl+alt+del twice, and attempt to login to the Administrator account, but I receive this error: Unable to Log You on because of an Account Restriction.
Other forums say that in the Server Configuration section, all you have to do is provide the username and a strong password from an administrative account on the computer, and it doesn't have to be THE Administrator. Well, I did that, but for some reason it doesn't recognize my username and password, it says something like "The credentials you provided for the SQL Server Agent are invalid". BUT THOSE ARE THE CORRECT CREDENTIALS FOR MY ADMINISTRATIVE USER! So I'm forced to use one of the accounts without a password, like NT AUTHORITY\SYSTEM. That's the only way I can get past this step.
Also, just FYI, on the next step, which is Database Engine Configuration, I am using Mixed Mode for the Security Mode. I AGAIN provide a password, and then add my current user (who IS an administrator on my machine!) to the SQL Server Administrators box.
But yet, it fails every single time.
This is pathetic and ridiculous. I must have tried to install this thing 15 times, that is not an exaggeration. I'm posting this on several other forums as well, maybe an MVP or Bill Gates himself can help me.
I have one of the log files from a failed installation. If someone would like to see it, I will post it.

PS : if you are talking about the Sql Server Agent Service, it is disabled for Sql Server Express. It is enabled only for the Workgroup/Standard/Dev and Entreprise Editions
Sorry, but I've tried the suggestion in that link, and it hasn't helped me.
For anyone wonder, the link is talking about the problem in Server Configuration where I enter my Windows user account and password (which is in the Administrative group), but it says the credentials are invalid. The link suggests that you need to either enter your Windows account (which I did, and it wouldn't let me go to the next step), or to use one of the built in accounts (which I also tried, but it gave me the " '' is not a valid login" error during the installation).
Any other ideas?
I haven't had any answers from any other forums either, so I'll just post my log file in case anyone wants to look at this:

Paypal not a valid payment method for family sharing

I have had paypal configured on my account for years. But now, for some reason while trying to set up Family Sharing on my iPad, it thinks Paypal is not a valid payment method. Should I be trying to set up Family Sharing from iTunes instead of my iPad?

I've read from others that at the preset time you have to use a credit card rather than a debit card. If you're using a debit card you might try entering a credit card instead, at least until the debit card option is restored.

The filter expression is on external data and could not be validated.

The filter expression is on external data and could not be validated. It may not be supported in Web browser forms.
I am reciveing this error in my infopath 2010 browser form when I am trying to filter a drop down list from sharepoint.
I thought filters were available on infopath 2010 browser forms or are they only available from values inside the form?
I did have a look around the forums but only could find this error occuring during beta stage.
Thanks

Ok, so you shouldn't be filtering in the form, because that means it downloads the entire list first and then filters out the items. That's client-side filtering. What you want to do is server-side filtering by doing a parameterized query.
Set the data connection NOT to automatically download
Add Form Load rules that do the following:
First, "Set a Field's Value" and set the position query node of the data connection to the value of "manager" (whatever the exact syntax is)
Then query the data connection
Doind this should make it ONLY download items where position=manager instead of downloading all items and filtering. This is a much better practice and was not even available in 2007, so you should make full use of it in 2010. Even so, what you
were doing should have worked anyway, so I'm not sure what's going on there.
When you do the filtered dropdown, your Source field should be the repeating group of the data connection, not the property itself. The property should only be selected in Value and DisplayName. The group should be in the Source field, and THAT'S
where you apply the filter.

i test the soa webservcies in a browserHi,
It would help if you could give us more details...
What type of soa webservices are we talking about here (JAX-RPC/BPEL/OSB)?
And how exactly are you testing your soa webservices in a browser (EM)?
A valid SOAP will have content-type: text/xml
You may be pointing to a invalid endpoint or you may have an authentication/authorisation problem, so you are receiving html instead of soap...

Javax.faces.FacesException: javax.servlet.ServletException: OracleJSP error: javax.el.ELException: Expression uses functions, but no FunctionMapper was provided

Guys,
I have a WebCenter Portal application which consumes few adf applications. This task is achieved by WSRP, and I am creating the portlet.xml in the adf application by the Jdeveloper.
These ADF applications are deployed in another server instance in Weblogic Server. However, the installation was made equal in WCP and ADF, which was considering the portal libraries for portlet consuming as well.
The thing is, in my embeddable weblogic, the application runs fine. However, when I deployed in the server, I get the following error in some adf pages:
<Sep 26, 2013 7:23:57 PM BRT> <Error> <oracle.adfinternal.controller.application.AdfcExceptionHandler> <ADFC-50018> <ADFc: No exception handler was found for an application exception.
javax.faces.FacesException: javax.servlet.ServletException: OracleJSP error:
javax.el.ELException: Expression uses functions, but no FunctionMapper was provided
at com.sun.faces.context.ExternalContextImpl.dispatch(ExternalContextImpl.java:415)
Is it possible the WebCenter libraries are conflicting? What is the best pratices in consuming ADF application from WebCenter?
Any help would be appreciated.
WebCenter version 11.1.1.8.

Method expression syntax error in jsp jsf 2.0 eclipse

hi i made a simple bean jsp project, n ussed el to call methods in backing bean n show some text on the basis of method called....
the project works perfectly fine, but theres a small issue, that eclipse jsp editor marks the expression as red n shows err.. the proj deploys fine on tomcat, n even works fine with expected results...
wat should i do to fix that err show by eclipse...
using eclipse helios with wtp 3.2, tomcat 7, jsf 2.0, el-api n el-impl 2.2 version jars in tomcat lib.... n latest jstl n standard jars...
eg of jsp call - <h:outputText value="#{myJsfBean.fetchCourseName(studentBean.courseId)}" />
backing bean fn -
public String fetchCourseName(Integer iCourseId){
 String theCourseName="";
 for(CourseBean aCourseBean:courseBeanList){
 if(aCourseBean.getCourseId().equals(iCourseId)){
 theCourseName=aCourseBean.getCourseName();
 break;
 return theCourseName;
jsp editor show err - Multiple annotations found at this line:
 - Syntax error in EL
 - Expression must be a value expression but is a method
 expression
for "#{myJsfBean.fetchCourseName(studentBean.courseId)}" part of the expression
its a trivial issue i think but annoying,, tried to search alot cudnt fix it....
plz help

my guess is that the project is not setup as being a JEE6 project and is being validated it as if it is a JEE5 application; the ability to be able to call methods with parameters through an EL expression is a new feature of JEE6 (or to be more precise: the el 2.2 API).
Perhaps you can specify in your project properties that this is in fact a JEE6 project? Eclipse Helios should support JSF 2.0 out of the box.

Bug in Tabular form Not Exist Validation, fails when creating multiple rows

Hi,
I have a Not Exist validation created for a Tabular form:
select 1 from my_table where col1 = :col1 and col2 = :col2Execution State: For created and Modified Rows
which is working fine when a row already there in DB
and I am trying to enter a new row with same data.
but when there's no data and I enter two rows with same data, validation does not fire, first row should allowed to enter
but for second row it should give error that data already exists, which is not happening.
for example,
let's say I have a row in DB with: 1, 2, 3
when I try to add a new row with same data ie. 1, 2, 3 validation fires and showing error, which is fine.
but let's say there's no data in DB and I am entering two rows with:
1, 2, 3
1, 2, 3
validation is not working this time, it is allowing to enter both the rows.
do I need to create a manual validation for this or what?
Apex 4.1.1.00.23

Hello Tauceef,
>> Now I got it, I was under impression that it will validate one by one row before insertion,
>> but it's going to check all the rows first, then do the insertion.
Just to clear things up, the APEX engine works exactly as you describe, but this is your problem.
The APEX engine do check\validate all the rows first, one row at a time, and only if all the rows pass validation, the DML processes kick in. The DML processes work on the entire Tabular Form record set (per page view, of course).
In order for your type of validation to work (the one that queries the database), as you want it, the validation and DML actions have to run together, row by row. This is not how things work, because it’s less efficient/optimal, and may lead to a situation where a certain row can fail validation, but other row(s) already been inserted/updated/deleted into/from the database. This could be a very tricky situation.
Vikram has suggested to rely on a database constraint, and control the APEX error message. This is possible, although I’m not sure that in this case, the Tabular Form will retain all the user changes, in case of validation error. You should check it.
Another option, which Marc hinted on, is to manipulate the G_Fxx arrays. In your case, you should loop through the new rows, compute their MD5, and make sure that all the rows have different MD5 values. This is on top of the current validation, which makes sure that the new rows do not already exist in the database.
Regards,
Arie.

Oh, I see that the title of your post is an error message? Ok. Well, the test class is declared as implementing an ActionListener. That means the test class must have an actionPerformed() method. Your test class apparently does not.
It does not appear that the test class needs to implement ActionListener. You are using annonymous classes as listeners.

Is not abstract and does not override abstract method tablechanged

I will remove all the gui code to make it shorter, but my problem lies with my InteractiveTableModelListener.
public class Meet extends JPanel{
private static void createAndShowGUI() {
        JFrame frame = new JFrame("MEET_dataTable");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.add(new Meet(), BorderLayout.CENTER);
        frame.pack();
        frame.setVisible(true);
public class InteractiveTableModelListener implements TableModelListener {
     public void TableChanged(TableModelEvent evt) {
if (evt.getType() == TableModelEvent.UPDATE) {
      int column = evt.getColumn();
      int row = evt.getFirstRow();
      dataTable.setColumnSelectionInterval(column + 1, column + 1);
      dataTable.setRowSelectionInterval(row, row);
class InteractiveRenderer extends DefaultTableCellRenderer {
protected int interactiveColumn;
public InteractiveRenderer(int interactiveColumn) {
      this.interactiveColumn = interactiveColumn;
public Component getTableCellRendererComponent(JTable dataTable,
     Object value, boolean isSelected, boolean hasFocus, int row,
     int column)
Component c = super.getTableCellRendererComponent(dataTable, value, isSelected, hasFocus, row, column);
   if (column == interactiveColumn && hasFocus) {
     if ((Meet.this.tableModel.getRowCount() - 1) == row &&
        !Meet.this.tableModel.hasEmptyRow())
         Meet.this.tableModel.addEmptyRow();
    highlightLastRow(row);
return c;
public void highlightLastRow(int row) {
     int lastrow = tableModel.getRowCount();
if (row == lastrow - 1) {
      dataTable.setRowSelectionInterval(lastrow - 1, lastrow - 1);
else {
      dataTable.setRowSelectionInterval(row + 1, row + 1);
     dataTable.setColumnSelectionInterval(0, 0);
public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
            UIManager.put("swing.boldMetal", Boolean.FALSE);
            createAndShowGUI();
}As i say, i have removed all the gui code to make it shorter, but in this code i create the table and add all the model to it. I am being returned with the error
Meet.InteractiveTableModelListener is not abstract and does not override abstract method tableChanged(javax.swing.event.TableModelEvent)in javax.swing.event.TableModelListener
what would be causing this error?
Cheers

Sorry, just figured out my silly error, the method is tableChanged not TableChanged.
cheers

...is not abstract and does not override abstract method compare

Why am I getting the above compile error when I am very clearly overriding abstract method compare (ditto abstract method compareTo)? Here is my code -- which was presented 1.5 code and I'm trying to retrofit to 1.4 -- followed by the complete compile time error. Thanks in advance for your help (even though I'm sure this is an easy question for you experts):

According to the book I'm reading, if you merely take
out the generic from the code, it should compile and
run in v1.4 (assuming, of course, that the class
exists in 1.4). I don't know what book you are reading but that's certainly incorrect or incomplete at least. I've manually retrofitted code to 1.4, and you'll be inserting casts as well as replacing type references with Object (or the erased type, to be more precise).
These interfaces do exist in 1.4, and
without the generics.Exactly. Which means compareTo takes an Object, and you should change your overriding method accordingly.
But this raises a new question: how does my 1.4
compiler know anything about generics? It doesn't and it can't. As the compiler is telling you, those interfaces expect Object. Think about it, you want to implement one interface which declares a method argument type of Object, in several classes, each with a different type. Obviously all of those are not valid overrides.
