Colo change on Error Message

Hello,
somewhere I have seen an example how to change the color of an label if an error message is there.
Knows someone about this?
Thanke,
ThomasW.

Not that I know of. You have no control over the standard validator.
The solution I offered you is not exactly a custom validator. A custom validator is a class that implements Validator (and, when required, the StateHolder).
I don't know what your requirements are but if you want to control a Label's color based on validation, I don't know any other ways.
An easier way to tell the user an error occured on a certain field, is to add a message close to the field in question. If you opt for that, then you can do it with the standard validators like this:
<h:message for="yearOfBirth" styleClass="error"/>
The "for" attribute identify the component ID for whom you want the error message(s) displayed.
Then, it's just a matter of adding the message(s) in JSF context...
this.getFacesContext().addMessage(clientId, new FacesMessage(message));
Look at the APIs for FacesMessage for more details on how to add a global or specific message for a given component id (clientId).
Cheers

  • Changing the error message

    Hi,
    <br />
    <br />How do I change the error message generated for a function such as an expired login.
    <br />
    <br /> <?php<br /> echo $tNGs->getErrorMsg();<br />?>
    <br />

    Hi Laurence,
    ADDT´s error messages are spread across all those XYZ.res.php files located in the includes/resources folder -- and in your case it seems to be the file "tNG_pro.res.php" which provides the error messages related to the login.
    In here you´ll find two message variants : one for ADDT´s "development" mode, and the other for the "production" mode. As you most likely will not need to edit the "development mode" messages which are identified by a trailing "_D" in the variable name
    (e.g. BADWORDS_SQL_ERROR_D), you´ll just need to adapt the "production mode" messages
    (e.g. BADWORDS_SQL_ERROR)

  • Programatically change the error message thrown by ADF Method validator

    Can I change an error message being displayed by an ADF Method Validator?
    The message of the method validator can be specified declaratively using the Wizard. But is there anyway I can programatically change it inside the body of the method validator?
    Inside a method validator i will check for about 5 conditions and each condition will have a separate error message to reflect the error correctly. I can't use a single message declared by the wizard.
    regards,
    Anton

  • Changing CAT2 Error Messages

    Hi,
    I'm looking to change the error messages displayed from CAT2 when an error is encountered on the timesheet screen.  e.g.  "System Status AALK is active"
    Is this possible?  If so, where can I find the messages?
    Thanks,

  • Change of error message into warning message

    While doing FBZP i have found the following error.
    Clearing acct only allowed for an outgoing bill of exch.pmnt
    Message no. F3029
    I am not able to go further, the above message is coming.
    I want to make the error message into warning message.
    Please suggest, how to overcome

    Hello BSR,
    The Error message F3029 is raised when the clearing account (T042I-VKONT) is filled but the payment method in question is not defined as "Bill/exchange".
    I assume that the field is not changable at the moment. You may make necessary changes (delete the entry or delete the specified account) with the instructions below.
    1. Go to Tcd: FBZP -> Click [Pmt methods in country]
    2. Select the entry for the erroneous country(?)/payment method
    3. Change Payment method classification to 'Bill/ex' and save
    Now you should be able to change "Set Up Bank Determination for Payment
    Transactions" table.
    If you still want to use this payment method, please change back to the original classification after making necessary changes in T042I.
    I believe this information would help you in resolving the reported issue.
    Best Regards,
    Vanessa Barth.

  • How to change java error message in transaction page?

    Hi experts,
    I want to ask, how to change ess critical error message to a user friendly message?
    the message appear because of user exit that we used on the back end.
    so here's the case:
    we use user exit of travel management to check end date of trip maximum is 2week from now.
    the user exit run correctly,
    but, the problem is it(error message) is appear in a new page. (and we can't undo or go back to the transaction page)
    how to make it appear in the transaction page? so the employee could easily change the date without input the transaction again from beginning?
    thanks.

    here is the error
    Critical Error
    A critical error has occured. Processing of the service had to be terminated. Unsaved data has been lost.
    Please contact your system administrator.
    , error key: RFC_ERROR_SYSTEM_FAILURE  
    this error come from user exit.
    i made validation for employee that they can't make travel request and expense more than 2 weeks (the end date)

  • Releasing Mass Change Worklist-Error Message No Administrator for this task

    Using transaction AR01 we create a Worklist and assign it to the Substitution Rule.  When we use Transaction AR31 and try to Release the Worklist so that the actual Mass Change can take place, we get the following error message.  "No Administrator for this task".  We've tried a user id with SAPALL and still get this error message.
    Does anyone know what this means and how we can get around this message?

    We have this working in our Test system without having to set up any workflow tasks for Fixed Assets.  I'm wondering if this has to do with the Productive client settings.  We had to make some changes so that we could use transaction OA02 in a Productive client.
    Any suggestions would be greatly appreciated.

  • Change B2B error message: "Error in R/3 system: document cannot be sent"

    Hi experts!!
    I had the requirement the B2B user not to be able to change orders from the past days.
    I wrote some ABAP code in MV45AFZZ user exit and the functionality works fine! I even receive my custom error message in the B2B but before my message i also get "Error in R/3 system: document cannot be sent. Call our hotline.."
    Is there anyway i can change this standard message in JAVA side???
    Thank you in advance!!

    In the ABAP side, set break point in BAPI_SALESORDER_SIMULATE and check the BAPIRETURN table.. Depending upon the stage and action on the order, the other RFCs you might focus on are SD_SALESDOCUMENT_CREATE  or SD_SALESDOCUMENT_CHANGE. The return structure is BAPIRET2 for this set of RFC.
    You might remove the "unwanted messages here.. or let them flow into the Java layer and tackle them there. That will require you to extend different xxxxStrategyR3 classes and overwrite certain methods in certain classes. The development is NOT streamlined here.
    Read the classes CreateStrategyR3 - there is a method performCustExitAfterR3SimulateCall  
    in ReadStrategyR3 - there is a method called replaceR3MessageTexts and in change..
    in ChangeStrategyR3 - there is a method called performCustExitAfterR3Call
    In all these places you have to read the appropriate table that contains the message and remove it. See ReadStrategyR3~replaceR3MessageTexts for some idea..

  • Changing the Error message in the background

    Hi Experts,
    Is there any way to catch the Error message in the background apart from changing the message type.
    Because the error message is coming from a standard function and I want my program should handle the error message. Whether this can be possible if possible can anyone please let me know the process.
    Thanks in advance.

    Hi Srini,
    The question is not very clear still I am trying to answer this.
    If my understanding is correct you are trying to run a standard function module in background task in your custom program and that FM is giving some error messages but not raising any exceptions and you are trying to catch those exceptions in your program. If that is be the case then yes you can definitely catch that error messages.
    Step 1 : Call function 'XXXX' IN BACKGROUND TASK
    Step 2: Call function 'ID_OF_BACKGROUNDTASK'
    Step 3: COMMIT WORK and WAIT.
    Step 4: Call function 'STATUS_OF_BACKGROUNDTASK' ---> passing the id number which you will receive in Stpe 2.
    Basically the step 4 would return you the error messages which would be visible in Transaction SM58.

  • Change default error messages

    Hello..
    I want to change the default error message in apex. for example I wanna change the Not-Null default error message so instead of "Field1 must have some value" I wanna get "Field1 must not be null".
    Thanks

    Hi Patrick,
    It’s an interesting reply, especially as the OP marked it as correct, but still I’m trying to understand something.
    As far as I can tell, you can use the translation system only for messages that was defined under a different language from the application primary language. For example, if you are working in English, and you are defining new text messages under English, with new text content, the Application Builder will ignore them as long as your application language is English (i.e. you can’t change/edit the internally used messages of your primary language). So, is this particular text message different?
    Thanks,
    Arie.

  • Changing SQL error Message

    Hi,
    I want to return a relevant Error Message whenever an SQL Exception occurs. For e.g. If a unique Constraint exists i want to return a relevant message like "A record already exists." Can i do the same?
    Maybe a good feature to have in the next version of Oracle, if it doesnt exist :)
    Regards,

    As 3360 points out, you cannot do this at the sql level (and a good thing too), but if you encapsulate all of your DML logic into packages (which is generally a good thing to do), then you can return wehat ever you want as an error message.
