The TableModel.getColumnClass() always return String class

Hi, anybody here has ever encountered and problem like mine? Please help if you do.
I have an JTable and the table model derived from AbstractTableModel, I use TableSorter from the tutorial to sort the table(I have also implemented my own sorting method, but the result is the same), but whatever the data type of the table column, the getColumnClass() method always return String type, so the table is always sorted by String type.
My implementation of this method is as following:
return getValueAt(0, columnIndex).getClass();
What is possibly wrong?
Please help, thank you so much!
Janet

Presumably the data in your first cell is a String object... therefore your code in getColumnClass() will always return String.class.

  • ADF pivot table HeaderCellContext always returns String

    I am creating a pivot table using my own array of a custom class: PivotCell[][].

    Please help.

    Hi,
    according to the documentation, this should not be the case. As you can see, the documentation explicitly calls toString() for the string representation: http://docs.oracle.com/cd/E28389_01/web.1111/b31973/dv_crosstab.htm#CHDGCBIG . You can narrow down the problem by using the default cell format and see what this returns

  • Why does the sum function not work when I try to add a column of decimal numbers?  The value is always returned as 0.  No problem with whole numbers but decimals do not work!

    just bought a MacBook Air and using Numbers to make a spreadsheet for financial purposes.  The sum function is working ok for whole numbers but when I try to sum a column of 2 decimal place numbers the result always comes back as 0.  Can anyone help?

    Hi laura,
    I suspect that your 2 decimal place numbers are formatted as text. Change the format of the column to currency and see it that works.

  • The Yahoo password in the mail settings of all my Apple devices has reverted to an old version and, no matter what I try, following advice from the community, it always returns to the old password.  How can I solve this issue?

    The Yahoo password in the mail setting on all my apple devices - iPad, iPhone 5, mini iPad - has permanently reverted to an old version.  I have tried all the suggestions provided by the community so far but nothing works. When I delete the account and re-enter the details, the updated password is recognised and seems to save but, when I go back into the account, the old password is the one that is there.

  • Default hostnameverifier always returns false ...

    Hi,
    I am trying to run wsdl2java by supplying an https URL. The JVM args that I am using are:
    javax.net.ssl.trustStore=E:/Romil/projects/AirDeccanPlugin/localhost.ks
    java.protocol.handler.pkgs=com.sun.net.ssl.internal.www.protocol
    On running wsdl2java, I end up getting the following exception:
    java.io.IOException: wrong hostname : should be <...>
    I've verified that the hostname (IP address) in the URL exactly matches the CN (IP address) in the server certificate .
    When I look at the JSSE code, it seems like the default HostnameVerifier always returns "false".
    I also couldnt figure out a non-programatical way of supplying my own
    HostnameVerfier to JSSE that returns a "true"
    Any solutions/thoughts ?
    Thanks and regards,
    Romil

    try this code before creating a connection
    com.sun.net.ssl.HostnameVerifier hv=new com.sun.net.ssl.HostnameVerifier() {
    public boolean verify(String urlHostname, String certHostname) {
    System.out.println("Warning: Hostname is not matched for cert: "+urlHostname+ certHostname);

  • Passive Sentences always returns 0 in Readability Stats - Word 2013

    Is there are workaround for the Passive sentences issue in Readability stats? I have seen this issue mentioned going back over several years, but no working answer. The following code always returns zero, but grammar checker does not:
    Sub Stats()
        Dim Stats As String 
        For Each rs In ActiveDocument.Content.ReadabilityStatistics
            Stats = Stats + rs.Name & " - " & rs.Value & vbCr
        Next rs
        MsgBox Stats, vbOKOnly, "Readability Statistics"
        Stats = ""
    End Sub
    If there is no fix in Word, does anyone know of a good third party option? We would like to have statistics in a comment on a paragraph by paragraph level.

    Hi Marc,
    Base on my test in word 2013 and 2010, I can reproduce that issue too, others work fine except passive sentences.
    On the other hand, I don't find third party option.
    I'm trying to involve some senior engineers into this issue and it will take some time. Your patience will be greatly appreciated.

  • Mkdir() always return false

    Hi all,
    I just want to create a directory from a standalone appli but the code below always return "8-("... Of course I have the rights to create/delete files because it is my C: drive.
    Thanks in advance for your help.
    String expDir = "C:\\mydir\\temp";

    Hi!
    The method mkdir() only creates one directory! So if the directory c:\mydir does not exist, the method doesn't work.
    Use mkdirs() instead.

  • CI - Powershell Boolean Rule Always Returns True

    I'm trying to create a configuration baseline / item for a particular piece of software using a powershell script of data type Boolean. However, I'm having the issue that the evaluation is always returning compliant whether the workstation is or not. The
    script is as follows:
    $ErrorActionPreference = "SilentlyContinue"
    $Condition1 = (Test-Path -LiteralPath 'HKLM:\SOFTWARE\Adobe\Premiere Pro')
    $Condition2 = (Test-Path -LiteralPath 'C:\Program Files\Adobe\Adobe Premiere Pro CS6\Presets\Textures\720_govt1_bar.png')
    if ($Condition1) {
    if ($Condition2) {echo $true}
    else {echo $false}
    else {echo $true}
    This script works perfectly fine when run locally and always returns $true or $false as expected. However it only ever returns Compliant when used in a CI. It doesn't matter what the state of the 2 conditions are, it always evaluates Compliant.
    Any ideas?

    I'm beginning to wonder if there is variation between how well this feature works on Windows 7 and Windows 8.1. I'm beginning to notice that it usually works well on 7 but I have constant hell with it on 8. The last thing I tried which seemed to work (assuming
    it was not just randomness) was accepting the default "Platform" settings of the CI/CB. Before I had chosen Windows 7 and 8.1 only and was never able to return any value except Compliant on 8. Accepting the all platforms default Finally
    allowed me to show a state of Non-Compliant on 8. This was using a powershell script of string data type as discussed previously.
    My latest torment is discovering how to force a true re-evaluation of an updated CI/CB. In my non-compliant Win8 example, I have added a remediation script to an existing Monitor-Only CI and configured it to remediate. In my Win 7 members of the collection,
    everything works successfully, the condition is remediated and the state reports Compliant but on the Win8, although the local Control Panel applet shows both the CB and CI to have new revisions and the evaluation shows it has run with a new date/time,
    the remediation script never runs and changes to Compliant.
    Any suggestions how I can force an updated CI/CB to really re-evaluate, not just report it has?

  • Businessobject.isValid always returns false

    Hi,
    I have created an object against to BOXXXXX business object by using below method having all the input values to formal arguments.
    CreateAction(actType As String,sfakna1 As String,Date1 As Date,Date2 As Date,description As String) As BusinessObject
    Dim boActivity As BusinessObject
    boAction = BusinessRootObject.BusinessFactory.CreateBusinessObject("BOXXXXX", "")
    We have some mandatory attributes and some normal attributes in BOXXXXX. We are setting values for all the mandatory attributes and setting 5 values to normal attributes. by using this code.
    With boActivity
                 ''''Normal attributes
                .SetAttribute("A", False)
                .SetAttribute("C", sfakna1)      
                .SetAttribute("D", description)
                .SetAttribute("E", Date1)    
                .SetAttribute("F", Date2)
                ''Mandatory attributes.
                .SetAttribute("F", "1")      
                .SetAttribute("G", "ABC")         
                .SetAttribute("H", "ACT")        
                .SetAttribute("B", actType)    
            End With
    But during verifying the boAction which always returns false in below condition.
           If boAction.IsValid() Then
           End if
    Please provide me the way to make that boAction returns true.
    Thanks in advance.
    Thanks,
    Naidu

    Thanks Shankar for your prompt response.
    Verified that we have set same lengh in our input parameters as in businessobject and verifed that each attribute(normal+mandatory) returns true. Verified with individually by using the below code.
    boAction.IsValidAttribute("A")  ''Normal
    boAction.IsValidAttribute("F")   ''Mandatory
    We have included all the mandatory fields in our function with same data types and same properties.
    Please suggest  me the inputs and share me the code if any to findout the causing attribute which makes boAction.IsValid() condition false.
    Thanks in advance

  • How do you change the number of rows returned by an advanced datagrid...Only displays 1000 rows....I

    I am using coldfusion to query an oracle table....Query returns approximately 2000 rows, however the max rows the datagrid will display is 1000.  Does anybody know how to change this...THANKS!!

    Thanks so much for your answer that sounds like a good idea...
    I found the answer to my initial problem...In my coldfusion I had set maxrows = 1000.  So the datagrid was always returning 1000 records even when a lot more than that should have been returned...When I removed the maxrows parameter in the coldfusion code, my datagrid was now been populated with the correct number of rows...
    thanks again for your help,

  • Cascading LOV always returns first row in af:query

    HI
    JDEV 11.1.1.3.0
    A strange thing is happening with my cascading LOV which is input text with LOV.
    I have a read only table with a query section. I then also bring up any of the tables rows in a popup with single record view where the row is then in an af:form for inserting and updating.
    Both the af:query and af:form have the cascaing LOV in them.
    When testing the cascading LOV in the BC Browser it works fine. When I use it in the popup in the af:form record it works fine. But in the af:query section, no matter which row I choose in the LOV, it always returns the 1st row of the LOV back to my input text component.
    Has anyone experienced this...any ideas?
    Thanks,
    Mario

    Aha...and the above log message lead me to the solution!! :-)
    The VO is based on an Oracle data dictionary view, DBA_TAB_COLUMNS. When you create the read only VO, by default it does not create any of the attributes as "key" attributes, because the oracle view has no primary key.
    Setting owner, tableName and columnName as key attributes solved this issue, now my cascading LOV works in the BC Tester, af:query component and my af:form component.

  • Boolean User Properties always returns TRUE

    Hi, I am trying to get some propeties from the user on the AD and I found out with the following issue, all the boolean attributes always return TRUE as value. The Code that I am using to extract them is the following
    foreach ($objUser in $objUsers)
     $bolPasswordNeverExpires = [boolean] $objUser.Properties['PasswordNeverExpires'];
     $bolEnabled = [boolean] $objUser.Properties['Enabled'];
     $bolAccountExpired = [boolean] $objUser.Properties['AccountExpired'];
    Could you please guide me into the proper direction to solve it. I looked up in most of powershell related topic and did not find a way to solve it. I even attempt using UserAccountControl Attribute to check Enabled status do not matter agains which value
    I check it, it always returns TRUE.

    Thank´s for the tip. Unluckily when I attempt it, if I left only
    $objUsers.PasswordNeverExpires or $objUsers.Enabled, it only return whites spaces and no comparison from True or False is feasible.
    If I change it to [boolean] $objUsers.PasswordNeverExpires or $objUsers.Enabled instead of using the Properties option, it returns False for all values.
    I attempt to use the UserAccountControl field for look up the property Ex: (objUser.UserAccountControl AND 2) for Enabled and it also returns True for all situation
    I look up for the properties on the ISE interface and the only ones displayed are the following ones:
    distinguishedname
    displayname
    whencreated
    samaccountname
