Error handling in the LAVA UI Tools addin

I had no idea where else to post this, but it amused me. Found in the "Dialog Box__lava_lib_ui_tools.vi" from the LAVA addin. Thought I'd share. The "No Error" is an event driven state machine.

Uh...is it me or is this flawed? If you pass in an error on the error in, it goes to the error case, and keeps the error, loops back around, and goes to the error case...forever. It doesn't matter if you put the Exit on the string shift register the first case statement evaluates the error case first.
Here is the support page on the LAVA UI Tools that I think you are talking about.

Local Module (Error-Handler) Failed the verify environment test

When attempting to start the Messaging Server, the following error
message occurs and the server fails to start:

19980226114147:Dispatch:Notification:Local Module (Error-Handler) Failed
the verify environment test.
 Module not Loaded.
 Startup Problem:
 Module Error-Handler is required for proper operation.
 Netscape Messaging Server Exiting!

This problem can be caused by a corruption to the configuration file
for the admin server that controls the Messaging server
(install_dir/admin-serv/ns-admin.conf).
Specifically, if the
Port setting is missing, the above-mentioned error will occur.

Add a valid Port setting to the
ns-admin.conf file and
rerun the /etc/NscpMail start command.

Is anyone having any idea about it...

Error handling in the InDesign SDK

I've almost reached the first milestone on my InDesign project and before I move on I decided to do a code review. One thing that caught my attention are the InDesign smart pointers and how they are used in the SDK samples and some of the open source stuff.
For example, here is some code from AppearancePlaceBehaviourUI.cpp in function GetCursor().
InterfacePtr<IHierarchy> sourceItem(const_cast<AppearancePlaceBehaviorUI*>(this), UseDefaultIID());
InterfacePtr<IHierarchy> parentItem(sourceItem->QueryParent());
InterfacePtr<IPlaceBehavior> parentBehavior(parentItem, UseDefaultIID());
if (parentBehavior == nil)
 InterfacePtr<IHierarchy> sourceContent(sourceItem->GetChildCount() ? sourceItem->QueryChild(0) : nil);
 if (sourceContent)
 InterfacePtr<IPlaceBehaviorUI> sourceBehaviorUI(sourceContent, UseDefaultIID());
 cursor = sourceBehaviorUI->GetCursor(globalLocation, modifiers);
Although the code works under normal circumstances, it strikes me as unsafe code.
sourceItem->QueryParent() is called without first checking that sourceItem is not a NULL pointer.
Functions of the sourceItem object are used again (GetChildCount() and QueryChild()).
The pointer sourceContent is checked before passing it to the constructor of sourceContent.
Function GetCursor() is called without checking if sourceBehaviourUI is not NULL.
For code tidiness pointers should really be tested against nil (i.e. if (ptrSomeObject != nil))
It strikes me as being inconsistent and easy to break - unless that is some of these interfaces are guaranteed to return pointers, in which case is there documentation to state as much? What would happen in the case of an exception such as bad_alloc - are they guaranteed not to throw?
I know that in some places (but not all), the samples use an "exception-style" approach of placing code blocks within a "do while(kFalse)" statement. They check for a NULL pointer and if they find one, break out of the "loop". This approach avoids deep nesting code.
It would be great if Adobe gave a statement stating what their code base will do and won't do (i.e. exception safety). A few definative error handling examples for developers wouldn't go amiss either.

Hi Dirk,
Agreed - I also would like to see more real world source code that explains concepts. It would be good to see samples geared towards operations on a very small set of types (i.e. Libraries, Library Commands) with tutorials explaining what the sample is trying to demonstrate. For example:
Library sample demostrates:
How to open a library.
How to close a library.
How to add items via approach A.
How to add items via approach B.
How to remove an item from a library.
How to remove an item from a library based on a specific criteria.
How to remove all items from a library.
Such samples would also demonstrate Adobe's idea of best practice - consistent code style, comments and error handling.
As Helmut25 posts in his thread "Tutorial for plug-in programming?" it would be good to see more step by step tutorials that don't just do a copy and paste but also explain clearly what is being done and why. You want to get into an Adobe developers head, understand their view of the universe and then apply what you've learned in your own projects.
Back onto error handling...
I've spent many a year doing Win32 programming (via C-style API, not MFC), so I'm used to using GetLastError() to find out why a function failed. Never really had reason to use SetLastError() and by and large avoided it. I think any API has to state what will happen when things go wrong (Microsoft's Win32 documentation is very good at this) and consequently you know how to write your code to account for such things.
One thing I like to do on standalone Win32/C/C++ applications is use a tool called AppVerifier, which allows you to throw various spanners into the works and see how your application copes. Shame there isn't something similar for testing plug-ins. I like to think that if InDesign crashes, it's not down to my code.

JSF error handling when the bean is not correctly loaded

Hi,
I am doing some error handling in JSF and I want to do it in an elegant way. I have the following scenario for error handling.
When the bean is initialized I load the bean with values from DAO which give SQL Exceptions.
Since the bean is not loaded I properly I have to send the user to an error page showing the error message why I am sending the user to this page.
I can do it by [ FacesContext.getCurrentInstance.redirect("/error.jsf") ] doing so I will loose all the FacesMessages that are added by the exceptions.
Instead I want to use the [ FacesContext.getCurrentInstance.dispatch("url") ] which will allow the transfer of the user but I get the following
16:59:39,341 WARN [lifecycle] executePhase(RESTORE_VIEW 1,com.sun.faces.context.FacesContextImpl@8537f9) threw exception
java.lang.ClassCastException: javax.faces.component.UIViewRoot
and the method that I am calling is
public static void programErrorEnd() {
logger.info("in the prgmErrorEnd mehod");
//intializing the contex object
FacesContext ctx = FacesContext.getCurrentInstance();
try {
//ready to dispatch the url.
//ctx.getExternalContext().redirect("app/error/prgmerror.jsf");
ctx.getExternalContext().dispatch("error/prgmerror.jsf");
} catch (IOException e) {
//TODO what to do when there is an error at this stage.
finally {
ctx.responseComplete();
}Thanks and Regarding

Just let it throw the exception and define an error-page entry in the web.xml which catches the specified exception (or a superclass of it or a HTTP status code) and displays the error.jsf page accordingly.

Error Handling in the SQL Trigger 2008 R2

Hi ,
I need some guidance in setting up error handling process in the table trigger. I have created a trigger on source database table and it load data to target table whenever there are any changes in last update date of source database ( given code below).
Problem : sometime I am getting error message ( like unique Index , data length mismatch etc) and my trigger don’t work and rollback the entire transaction.
Requirement : If there is an error with the insertion, I would like to move that error-inducing record into an error table . Any guidance much appreciate. thanks!

The first choice is stored procedure. Trigger should be last resort.

Error handling in the LVWebUIBuilder

Impressive stuff.
I don't see any error handling mechanisms in the LVWUIB. Are they there, and I'm missing it?
Thanks,
Joe Z.
Solved!
Go to Solution.

Hi Joe,
With the error cluster, you can use the Unbundle Error function (http://zone.ni.com/reference/en-XX/help/373286A-01/uibuilderref/wuib_unbundle_error/).
To add error handling to your subVIs, you need to create error terminals from any function that has error inputs and outputs. Then, select the View tab and click SubVI Settings. From there you can add error in and error out terminals.
You can create error windows using the Display Debug Assert function (http://zone.ni.com/reference/en-XX/help/373286A-01/uibuilderref/wuib_display_debug/):
Note that I have to invert the error boolean to make the dialog pop-up.

Error handling and the resulting messages to the user

Hi all.
I have a question about displaying error messages from custom callback classes.
I've written my own PasswordValidation class, and when the user's password doesn't pass validation, I throw an AMException with the text of the specific reason the password was invalid.
I see this in the stack trace in the identity log files, but in the GUI from Self Reg, all I get is a generic "An error occurred while storing the user profile."
Is there a way to have my specific error message be the one displayed to the user? The generic one doesn't give the user much to go on as far as what needs to be fixed.
I'm using Identity 6.1 on Solaris.
Thank you for your time.
chris

As a followup, if the user account is created via the console, not through self reg, the appropriate error message does appear to the user. So it seems like just Self Reg isn't picking up the error messages from the callback classes.
Thanks!
chris

How to treat error handling in the consumer loop in the queue message handler structure?

Hi,
I'd like to know how to stop the producer loop(event loop) in the QMH structure when the error happened in the consumer loop.
I've construct a demo code by myself as the attached image, but it's a pity that I have to create a recdundant indicator "End" to trigger the value change event to stop the program. This is not a good way to do it. Could someone give me some better idea how to deal with it? Very appreciated to you sharing ideas.

Concerning your doubts about the "traditional" implementation of this pattern, I hear you. As I have written many times before, its main benefit is that it is easy to explain in a training class. It unfortunately has a lot of drawbacks.
Tim's suggestion about User Events, is a good one. But to use it to the best advantage, you will need to get away from having everything on one block diagram. If you think about it there is no real need for the two loops to be on the same block diagram and a lot of really good reasons for them not to be. For example, if they are in separate VIs, they can both be event driven and any communication problems between loops evaporates.
Its also more modular, easier to maintain, more reusable, etc...

Error handling in the integration process

hello all,
here i have a situation in which , i have to do some work in the integration process step of the integration repository, i am given a txt file which has a 100 records each is a employee detail, the last record has the summary total , that is last row contains the sum of a particular column.
now i am supposed to do somthing in integration process, so that my program should add all the values of the specific field , of all employees and check it with given sum, if it tallies, we have to go ahead, or else send back a mail saying there is error input,
any help will be greatly appreciated.
thank you

Hi kutumba,
in the container of the BPM you crate a element of type integer.
As I told you in your other thread you need a multine-container element taht is looped in a BLOCK.
In this BLOCK increment your counter-element. After the Block define a condition for sending/not sending.
Also refer to you SAP-BASIS SWV! There are helpful samples!

Where is the Error-Handler config DB file?

Where is the Error-Handler config DB file?

All the Config DB files are in the config directory under the
postoffice directory. Each config file has the same name as the
Module it's the config for (e.g. Error-Handler contains the configs
for the Error-Handler.)

Look in the database alert file - in the "bdump" directory
Look in the trace files in the "udump" directory
If still no wiser:
ALTER system SET event = '31098 trace name context forever, level 2' scope=spfile
Try again and look for the trace files starting with "s..." in the "udump" directory.

Accessing the original message body in Error handler

Hello everybody,
The loanGatewy3 proxy service in the OSB tutorial uses a stage in the request pipeline for validation. If a validation error occurs the error handler reports the original body message using a reporting action.
Now if an error happens inside the Routing node; and if an error handler is defined to report the original message ($body), the reporting action will report the error message not the original message. It seems that the $body variable contains the erroneous response instead of the original message. So is there a way to access the original request $body inside a node error handler?
Best regards,
Tarek

you can always put the original message into a dummy variable $origMessage, then in the event of an error report on $origMessage not $body
cheers
James

. What is the error handling mechanism available in ODI ?

What is the error handling mechanism available in ODI ?

We have something called CKM in ODI. It provides option of Static control and Flow control.
What you need to do is provide the proper constrains / validation rules on the source and target models. When you execute the interface , if any of the rule is violated , those rows goes to E$_ tables also called Error tables.
Static control example :
Before executing the interface , you can check the data health of your source model.
Flow Control example :
Thus for example you have 100 rows , out of which 10 rows violates the rule , then 90 rows will go to target table and 10 will go to error table. If you correct the values or modify the constraint and re execute the interface , those 10 rows will also go to target.
Other than that if you mean Error handling in the package or load plan , you can use OK and KO appropriately and route the flow as per your requirement. This is all custom approach , which will vary from design to design.

Need to Turn it OFF the Notification used by the AIA Common Error Handler.

Hi All,
My requirement is to turn it off the Notifcation send by the AIA common Error Handler, when the error occurs in the AIA ecosystem.
Error Handling framework given by AIA does the Notification and Logging feature. In my case I need only the logging, but not the Notification. Notification has to be turned off for a time and has to be turned on when it is required.
1) I can acheive this by removeing the email account file (ie. ns_email.xml) from the server directory and can be replaced at the time when required,but this needs the restart of the Server.
Any Idea how to turn it off the notification and turn it on when required ?
Thanks,
Ashok.

Hi Rohit,
Thanks for your reply.
Is there any way to turn it off the Notification, because if we retire the ReadJMSNotification Service all the error message are stayed in the Topic and we have to manually drain the message from topic.
And one more thing is how the error messages are published to that AIA.AIA_Error_Topic.
Thanks,
Ashok.

Mapping and Error handling in Seeburger Adapters ?

Hi,
1. In B2B integration part of PI.Whats the way of doing mapping in XI mapping editor and error handling in the mapping ?
2. Do you think SEEBURGER BIC mapping designer is must for developing maps ? cant we develop same maps in XI mapping editor?
Thanks and regards,
Ram.
Edited by: Ramakrishna kopparaju on Sep 30, 2008 12:27 PM

Whats the way of doing mapping using seeburger adapters
The standard mappings are part of Seeburger Suite and if any additional mapping has to be accommodated, then custom mapping could be developed in Seeburger BIC Mapper tool. This has to deployed on adapter engine then. The other mapping is the normal XI mapping (message, java, xsl) which could be performed based on business logic.
error handling in the mapping ?
The easiest way is to raise Alert based on the errors in mapping.

Prateek
