Update Row return blank page

Hello there,
I created a master detail form with a tabular form that will update two columns (Comments and Status)  when I click a button to applied changes. The master region is a dynamic list of value that receive a character value (eg Error Code) and this dynamicly will trigger the detail to populate the tabular form depending on the number of Error code rows in the database. When I pass the Error Code value and this Error Code  has less then 50 rows on the tabular form and when I click the button to perform the update,  the two columns will update without problem. When the Error Code has over
50 rows on the tabular form this will execute and will show a blank page. Is anyone have notice this type of problem and did you solve it?
Your insight is much appreciated.

Hi all,
I've found the reason of getting a blank page. I was creating a Section for each course, hence there are a total of 220 sections in the page I was trying to retrieve. When I reduce that to 217 section, the page work fine.
However I would like to know if '217' is the maximum number of section for a page?
Cheers,

    Hi
    I would check the c:\program files\wfavvid\log\MADM logs for any major EXCEPTIONS (search for them in Caps, and try to make sense of what they are telling you
    If you don't have any luck with that, it's possible to delete the appadmin website from Tomcat and it will rebuild the site when you next restart the Node Manager. Go into c:\program files\wfavvid\tomcat_appadmin\webapps, and delete the appadmin folder. There will also be an appadmin.war file there, don't delete that as it contains the compressed website files. When you restart the node, it will be rebuilt and may be fixed.

    Hi, Sly101.
    I would recommend closing any open applications in multitasking and restarting the device.  If unfamiliar with multitasking, I have included a screenshot on how to process an application close.  Test the results after processing these steps.
    If the issue persists, see the section labeled Troubleshooting on an iPhone, iPad, or iPod touch in the article below.

  • XSLT Transformation returns blank page

    Hi,
    apologies for the NOOB Question.
    I'm trying to prepare an XSQL demonstration for work and have hit a problem, which I'm sure is just a configuration issue.
    Using JDeveloper 10.1.3.3.0 I have created an XSQL page which returns a few rows.
    I've written an XSL stylesheet to transform the data into an html page.
    However, the browser is just showing a blank page.
    I've tried the following:
    1.) Calling the XSQL page with the '?xml-stylesheet=none' parameter.
    The browser displays the unprocessed data correctly, so there's no problem with the XSQL itself.
    2.) Saving the output from the webpage as a seperate xml file and applying the stylesheet to it
    (by adding the line <?xml-stylesheet type="text/xsl" href="bhwtest1.xsl"?> to the saved output, and opening in the browser.
    This works fine and shows that the stylesheet works OK.
    I've also tried opening the stylesheet directly in the browser to check that the path that I specify to the stylesheet is valid. This also works, so
    the path to the stylesheet is correct.
    Any ideas what I can try next?
    Thanks for your suggestions,

  • Printing to PDF from CrystalReportViewing returns blank page

    Hi All,
       I have a web report that I run. When the report generates in the CrystalReportViewer I see my results. However, if I click the button to Print to PDF, it results in a PDF with no data. If I click on the Next button as well to go to the next page in my report, it returns blank results.
    This apparently started happening when I used date parameters being passed to my stored procedure:
            parameterField = report.ParameterFields("@callstdate")
            parameterField2 = report.ParameterFields("@callendate")
    I'm using VS 2008 and CR2008.
    Any ideas why this is happening?
    Thank you in advance,

    1)Any export type I use returns no data on the exported report
    2)Changed PDF to ActiveX and it printed the report with no data
    3)Remove parameters from my webapp and let the Viewer prompt for them. Now PDF works and everything else.
    Here's my code:
        Protected Sub display_report()
            parameterField.CurrentValues.Clear()
            parameterField2.CurrentValues.Clear()
            parameterField3.CurrentValues.Clear()
            CrystalReportViewer2.ParameterFieldInfo.Clear()
            parameterField = report.ParameterFields("@callstdate")
            parameterField2 = report.ParameterFields("@callendate")
            parameterField3 = report.ParameterFields("Group")
            For Each li As ListItem In Me.ListBox1.Items
                If li.Selected = True Then
                    ' Add all parameters value here
                    parameterField3.CurrentValues.AddValue(li.Value)
                End If
            Next
            report.SetParameterValue("@callstdate", CDate(st_date.Text))
            report.SetParameterValue("@callendate", CDate(st_date.Text))
            CrystalReportViewer2.ReportSource = report

  • WCM_PLACEHOLDER returns blank page while WCM_BEGIN_EDIT_SESSION works fine

    Hello there,
    I have created a website in SiteStudio (via JDeveloper) with the site assets as in the following link:
    http://download.oracle.com/docs/cd/E14571_01/doc.1111/e10613/img/region_definitions.gif
    Note that all the elements in the above link are checked in UCM.
    I can edit the datafile which is in UCM via:
    http://127.0.0.1:16200/cs/idcplg?IdcService=WCM_BEGIN_EDIT_SESSION&dDocName=SSD-DATAFILE
    However I am unable to see the contents of the same datafile via:
    http://127.0.0.1:16200/cs/idcplg?IdcService=WCM_PLACEHOLDER&dataFileDocName=SSD-DATAFILE&placeholderDefinitionDocName=SSD-CONTENT-PHD
    No matter the value I type for the parameter dataFileDocName I always get a blank page.
    If I change the URL to:

    I get the following response: It is not possible to calculate the path to the content item 'SS_DEFAULT_REGION_TEMPLATE'.
    The thing is that I don't know why UCM is trying to find +'SS_DEFAULT_REGION_TEMPLATE'+.
    Can anybody shed some light on what is happening please?

  • CF8 returns blank page

    Hi,
    I have an Intranet application running on a CF8 Enterprise edition and the last few weeks we see a strange behaviour of our server: sometimes it just returns a blank page.
    This occurs in the morning of a random day, when the first people try to log in to the Intranet. When we view the source of the returned page, it is totally blank, not even a hint of HTML code. We tried finding a clue in the log files, but as no error whatsoever is produced, no trace can be found.
    The current solution is restarting the 'ColdFusion 8 Application Service' and everything works as normal. It intervals at around 5 days.
    CF version : 8,0,1,195765
    Operating System : Windows 2003 (5.2)
    Java Version : 1.6.0_04
    Enabled Session and Application variables.
    Does anybody out there experiance the same or comparable problems? Does anybody know of a more permanent solution?
    Thanks for ready.

    Here we go :
    1. We used the Monitoring tool from the moment we upgraded to CF8, mainly to set alerts on JVM and unresponsive server. As in the logfiles, nothing of interest appears on the monitor.
    2. I verified that the key is valid and no doubles exist on the network.
    3. See below
    4. Other templates do not render either. If I call the Intranet by another alias (being IP or machine name) it does create a new memory store and initializes the app correctly. (We normaly work with an alias to call the Intranet, I also verified that the alias is correctly translated and I do call the correct server)
    5. I hard-coded <cfreturn true> at the end of the OnRequestStart method. (I also read that post somewhere I recall )
    Code for OnError :
    <cffunction name="OnError" access="public" returntype="void" output="true" hint="Fires when an exception occures that is not caught by a try/catch.">
            <cfargument name="Exception"    type="any"        required="true"                    hint="Struct identical to a cfcatch variable">

  • Return Blank page

    Hi all,
    I was trying to access a page with 220 courses and a total of 500 tracks. But page returned was a blank page with scroll bar. May i know if there is a limit for Sections or courses per page in iTunesU?
    These is the url i try to access.
    https://deimos.apple.com/WebObjects/Core.woa/BrowsePrivately/anu.edu.private.au. 2771899376

    Hi all,
    I've found the reason of getting a blank page. I was creating a Section for each course, hence there are a total of 220 sections in the page I was trying to retrieve. When I reduce that to 217 section, the page work fine.
    However I would like to know if '217' is the maximum number of section for a page?

  • Since new update, I get blank page pop ups instead of page requested

    Last week, I got the latest update for Firefox. Since then, whenever I connect, for example, on Facebook and want to open Farmville, Facebook will open but I will get a blank page for Farmville. I tried sending an email to my internet provider, from their site, but email page never showed, instead, I got the blank page pop up.

    This may be caused by a problem with an extension or theme, try the procedure in the [[troubleshooting extensions and themes]] article.

  • Cflocation returns blank page

    I have a page that redirects the user after they have successfully logged in.  Everything was working great on my test server but when I uploaded it to launch the site the redirect after logging in stopped working.
    User enters info and hits submit
    Code logs in user
    Blank page is shown
    Refresh that page (without resubmitting form)
    User was successfully logged in.
    So the page is going to the login script, they are being logged in but the cflocation is not redirecting on my IIS server but it was on Apache.  There are no cfflush or cfdump tags found in the entire site.
    Any ideas? Thanks!

    Thanks for the response!  I've checked all the rules and files. All is good.
    It looks to me that everything is working but the cflocation.  If I manually go to the page the cflocation was being redirected to all of the code executed before the cflocation has been executed (logging the user in).
    It's just the cflocation not working.
    An other thoughts?  Thanks again!

  • Running Powershell command from PHP returns blank page

    Hi. :-)
    I have this script :
    <?php
    $q = shell_exec('powershell Get-Help');
    echo $q;
    ?>
    This works well and gives me output.
    But... When I change Get-Help with Get-VM it gives me blank page as ouput. I have simillar problems with other Hyper-V cmdlets.
    This is code 1:
    <?php
    $q = shell_exec('powershell Get-VM');
    echo $q;
    ?>
    This code gives me blank page.
    Code 2:
    <?php
    $q = shell_exec('powershell Start-VM 'Vm1'');
    echo $q;
    ?>
    This code gives me that it cannot find VM with that name.
    What's the problem, what to change in script or system settings.
    Note: All this commands WORK and gives me output when I run it from cmd
    Things that I did:
     1. Changed execution policy to Unrestricted
     2. Added 2<&1 at the end of shell_exec.
    Thanks in advance.

    Hi,
    I think we should run powershell as adminitrator to get VMs.
    Start-Process "$psHome\powershell.exe" -Verb Runas -ArgumentList '-command "Get-VM"'
