View the Error Message customized to Apex

Hello

I created a form master / detail on Emp and Dept tables. In the Dept table, I have deptsal column, which is updated by a trigger on the table EMP.
After trigger DEPT table a:

create or replace trigger "TRG_DEP_SAL".
BEFORE the UPDATE on "DEPT".
FOR EACH LINE
BEGIN
IF: NEW.deptsal > 100 THEN
RAISE_APPLICATION_ERROR (-20001, 'Dept too high salary!');
END IF;
END;

Then, when I get the salary on Apex shape, which increases the limit of deptsal for example 100, it gives the following error message:


Internal error in the routine mru: ORA-20001: error in MRU: line = 1, ORA-20001: Dept too high salary! ORA-06512: at "ZAHIDKHANUK. TRG_DEP_SAL', line 4 ORA-04088: error during execution of trigger ' ZAHIDKHANUK. TRG_DEP_SAL' ORA-06512: at "ZAHIDKHANUK. BIUD_EMP', line 11 ORA-04088: error during execution of trigger ' ZAHIDKHANUK. BIUD_EMP', to update 'ZAHIDKHANUK '. "' EMP ' defined 'EMPNO' =: b1, 'DEPTNO' =: b2, 'ENAME' =: b3, «JOB» =: b4,"MGR"=: b5, 'HIREDATE' =: b6,"SAL"=: b7,"COMM"=: b8, 'ID' =: b9 where 'EMPNO' =: p_pk_col
Error failed to process the update.
Ok


How can I view my message?

Thank you

Hello

Yes, you can do it. You create a validation of the page that moves through the records in a tabular form, checks entered values, and then returns an error message.

Create a new validation. Set it to a Page-level validation, select PL/SQL and then function that returns the error text, then give it a name. The PL/SQL will be something like:

BEGIN
 FOR i IN 1..APEX_APPLICATION.G_F01.COUNT
 LOOP
  IF TO_NUMBER(APEX_APPLICATION.G_F04(i)) > 100 THEN
   RETURN 'Item ' || TO_CHAR(i) || ' - DEPTSAL must not be greater than 100';
  END IF;
 END LOOP;
 RETURN NULL;
END;

It will loop through the records in column 4 and check the amount. If it is greater than 100, an error message is generated displays the line containing the error. This will stop the process on the first error. If there is no error NULL is returned that indicates that the validation test was successful.

You need to replace G_F04 with the correct column for your page - make a display on the loaded page Source and check the attribute "name" for the column. G_F04 is for "f04", G_F05 is for "f05" etc.

    Hi all

    I write my own form Manager and I try to display the errors of form without using field errormessageforeach drop end learning.

    I'm able to show errors in fields, but I want to show them next to the fields.

    How can I get this feature?

    Kind regards

    I can think of a simple solution is to define a map container in the FormHandler add the error message and on jsp display the associated value, for example like this

    psudeo code

    Map errorMap = new HashMap();

    {if(FirstName==null)}

    addFormException (new DropletException ("Please enter first name"));

    errorMap.put ("firstname", "Please enter the first name");

    }

    in jsp

    Make sure that no error just to give you an idea wrote the untested code.

    Hope this helps

  • View the Error Message in the Console of the IOM

    I have a scenario where the user triggers the request for the third time for the same RO then error message should be displayed to the user and this RO status must be set to revoked.

    To do this, I have the unconditional task that returns R as response when the user raises the demand for the 3rd time. Based on this response, I called another task that will display the error message to the user.

    But the problem is that the State of the requested 3rd RO is showing that Provisioning and Validation of the system as pending. But I actually traced the answer R to revoked.

    I don't know why the Validation system is showing as pending. But if I remove the task that shows the error message to the user, then the status of the object shows as revoked.

    This part of the requirement is POC and the receiver Office that I mentioned above is a dummy ro.

    Pls help me solve this problem.

    Waiting for your valuable answers.

    Thanks in advance.

    Hey, you made it rejection Fatal because it shows you the status rejection.

    If you select error then it does allow you to go further.

    I would recommend using error, it will not allow the user to start the service and displays error you make provisioning for the third time, so you are not allowed to do this.

    Hello

    Step 1:-create a branch to return to the page you requested...
    for example.

    if :P1_VALUE = 'SO AND SO' then
    return required_page_no;
else

  • When I boot FireFox on the Mac, the error message 'well, it's embarrassing... ' appears view full page on the Tools menu.

    When I boot FireFox for Mac (OS x 10.6.8), the error message 'well, it's embarrassing... ' back to PAGE VIEW covering the menu, tools, docking station, office,. Clicking on a 2 error message options 'restoration' or 'close' doesn't work. Since I can't access options menu under the eyes (and pressing 'ESC' does not display page, my only option is to force quit FireFox. I downloaded a cool FF program, but the same thing happens. How can I fix when I can't access the menu or tools, etc. ?
    PS. I'm going to use Safari to send this message.

    Well, it's boring.

    On Mac, command + shift + f should toggle the display between the ordinary and full screen. Does it work?

    If you can still access the menu bar, one of the Firefox settings file may be damaged. Try this, assuming you have the main toolbar:

    Open the settings folder (AKA Firefox profile) current Firefox help

    • button "3-bar" menu > "?" button > troubleshooting information
    • type or paste everything: in the address bar and press enter/return

    In the first table of the page, click on the button 'show in Finder '. This should start a new window listing the files and the folders.

    Leave this window open, switch back to Firefox and output:

    • "3-bar" menu button > button "power".

    Pause while Firefox finishing its cleanup, then rename xulstore.json to something like xulstore.old. If you see a file named localstore.rdf, rename this to localstore.old.

    Launch Firefox back up again. Windows normally appear again?

  • Jdev11g; Customizing the Error Messages from the Business components

    Hi all

    Need help on two or three issues, I am confronted with this: -.

    (1) although I gave the error message for Houston-25013 and JOB_ID_PK, always I get after the error message on the user interface, when you save the new record
    "Too many objects correspond to the oracle.jbo.Key [AD_PRES primary key]."?
    (2) why do I get "Attribute in HrModule.JobsView1 JobId is required." with above the error message in the error popup window?
    "(3) when removing the record, even though I'm getting desired error message on UI ' oracle.jbo.DMLConstraintException: there are the child records to selected record", why the error message is prefixed by "oracle.jbo.DMLConstraintException".?

    Hello

    Just put the number of the error, instead of Houston-25013 1), try with 25013

    For 4) you must create a second resource group with the locale in his name. ex I have a BCBundle.java for English and a BCBundle_fr.java for the French
    Check the guide FusionDev and WebDev guide for information on the locale and the beams of the resource.

    Mary:

    Model based buttons are indeed harder to gray-out/disable HTML buttons are. Demanding that the other buttons on the page are also subject to the same action more complicated the problem.
    It may be possible to have your custom error message to return only for error "dup submission."

    Change the model of error as follows

    Set the "Error Page template" in the "error page control model ' as '.
    #MESSAGE #.
    In the footer of the model section add {code}

    4 is the issue limited only when you try to play the DVD?

    Xerces.dll error message can be caused by corruption in the Windows System.

    Check out the link to use the System File Checker (SFC) tool to troubleshoot missing or corrupted system files in Windows 7.

    SFC/scannow is a very useful command that you can use in any version of Windows. When the SFC (System File Checker) command is used with the/scannow switch, the tool analyzes all the important files of Windows on your computer and replace if necessary.

    Missing and the corruption of the operating system (like many DLLs) files are probably the main cause of the major problems of Windows. In view of this, plus the fact that the SFC /scannnow is completely automatic and very easy to use, the tool should usually be your first troubleshooting step.
