ErrorPageMBean.getApplicationName() returns always "?"

SupportIvyTeam — Mon, 10 Dec 2018 10:50:16 -0500

I have defined my own error page, which displays a link to the application start page. To get the current application, we use ErrorPageMBean.getApplicationName(), which always returns "?".

How to create ErrorHandling process for dependent project model?

trungdv — Wed, 14 Nov 2018 02:41:24 -0500

Hi all

As you may know that in ivy, it allow to create Process with name ErrorHandling to centralize error handling

This process must name as ErrorHandling and put inside Processes.

Now I have another project that depend on this project and when i create ErrorHandling on that, ivy say:

 Can't create process with same name.

How can i solve this issue?

Thanks

Prevent/by-pass ivy:error:loop

rhorber — Tue, 10 Apr 2018 09:45:14 -0400

Hello everyone

We have a process, where we parse a CSV file. For each line a web service is called (in a loop). Our error handling catches timeout and other errors with Error Start elements.

The problem now is, on the second timeout (or other) error, Ivy throws an ivy:error:loop error, because it is the same sender and receiver element as also the same task.

What are possible solutions for this problem? We can't send all lines at once, because the web service is third party, and also it is crucial to catch every error to handle it.

Any help will be appreciated.
Thanks.

Here's a picture of the process:

Global Error Handler HTML Dialog not being loaded

ToanLC — Wed, 28 Jun 2017 23:32:16 -0400

Recently I encountered an problem that the HTML Dialog of my global Error Handler cannot be loaded & the HTML Dialog that got error thrown is not being loaded.

The demo project for reproduction can be found here : https://github.com/toanlc0912/demo-error-handler

The Ivy version I'm using is 6.2. Not really sure if I did anything wrong on the structure of all the error element

ErrorHandler for "Dialog instance is not available anymore"

Maxim S — Fri, 02 Jun 2017 02:55:24 -0400

Dear Ivy Team.

Is it possible to catch error "Dialog instance is not available any more" via ErrorHandler process?

I made ErrorHandler the similar as in example ErrorHandlingDemos with error code: "ivy:error". But it's not working. We would like to move user to home page when that error happens. We use SVN for a project in workspace and we wouldn't want to change web.xml in the designer (for example to replace error page) because it is beyond SVN.

Thanks!

How to avoid the Error Http Status Code 409?

Jailson Brito — Tue, 07 Feb 2017 18:32:50 -0500

Scenario:

user1 authenticates and starts a task;
Then, user1 closes the browser window with the task open;
Finally, authenticates again and try to do the task.

Then, it throw the Error: "Error Http Status Code 409", ConflictRequestException: "You cannot work on the task '305 - User 1 - Task 1 - ' with the identifier '41' because the user 'user1' is currently working on it.".

The simulation doesn't start before the error, so I am wondering if it could be just a configuration on Axon Ivy. My Question is How to avoid the Error Http Status Code 409?

Any help is appreciated.

Notes:

In my user application, the tasks are showing using the approach explained in findWorkTasks() never returns tasks in TaskState.RESUMED state;
Since it's not reliable in all browsers, I am avoiding to handle the window closing: Detecting when the user closes the window or tab of the browser in a Html Dialog;
It seems that the Portal handles the action differently for RESUMED and SUSPENDED tasks, that's my plan B;
Engine Version 6.0.5;

Is it possible to set the 404 error Page more specific

roland — Mon, 17 Oct 2016 14:15:01 -0400

Hi,

is it possible to modify the error page for file not found more specific?

404 is raised if the Task is done and if the Task is resumed. Is it possible to show this information to the user?

best regards Roland

ErrorHandler in multi modules (Ivy Designer 6.3.0)

Hap Em — Fri, 07 Oct 2016 10:57:18 -0400

Hello All,

As you see in the picture, I have 2 modules (ErrorHandlingDemos and ErrorHandlingChild). In each module, I has created ErrorHandler Process --> I got the compile error message in the console --> but, everything works fine (although compile error occurred) --> Updated for this case: i renamed ErrorHandler by another name --> no compile error anymore :)
I removed ErrorHandler process in one module to solve the compile error (actually, ErrorHandlingChild module). But when the error occurred in runtime, the application didn't call to "Display error" of ErrorHandler process in ErrorHandlingDemos --> I think it should show "Display error" of parent module.

Could we only define the ErrorHandler in parent module?

Thanks for supporting!

ivy.html.startref throws exception on server

Stelt0 — Thu, 18 Aug 2016 18:05:26 -0400

Hello all,

I just found out that this method:

ivy.html.startref("Start Processes/DashboardPages/DefaultApplicationHomePage.ivp")

throws an exception on the ivy server, but not in the Designer

Why ? What am I missing ?

Error handler redirect to Web Page or User Dialog ?

Stelt0 — Thu, 04 Aug 2016 14:38:50 -0400

Hello All,

I have an interesting situation.

I have a User Dialog with interactions and a bit complex Logic. There is a point in the process where I`m trowing an exception and I want to redirect the user to an error page:

I want to catch the exception in the business process where to do the redirect. Here is the confusing part:

If I redirect to User Dialog, everything is working correctly:
If I redirect to Web Page (JSP from the CMS) it is trowing an error.

Is this a bug or wrong architecture from my side ?

anyway, what is the best practice for managing exceptions in User Dialog`s Logic?

Best Regards, Yordan Yunchov

Custom servlet filter

qtdan93 — Mon, 25 Jul 2016 12:19:38 -0400

Hello all, I have a question : Can I create a custom servlet filter (interceptor) and register it to Ivy Engine Server, so whenever a request is sent to the server, it must pass this custom filter (interceptor) first? And I also see that Ivy has some filter classes in package "ch.ivyteam.ivy.webserver.internal". So if I can register my custom filter, when does it intercept the request (before or after filter in the package above) ?.

A little bit about my problem : We have one case that whenever the admin changes the LDAP directory, if the user already logged in the application now no more exist in the new LDAP directory, the exception "PersistentObjectDeletedException" will be thrown. This exception happen when the filter in the package "ch.ivyteam.ivy.webserver.internal" start filtering the request!!

Ivy server fails to start because of "Page Archive Engine Manager"

ivyUser — Thu, 14 Jul 2016 18:43:29 -0400

Dear Ivy Team,

I'm facing a strange issue that never happened before: the ivy server cannot be started anymore. It refers to a so-called "Page Archive Engine Manager". Nothing special has been changed in the configuration since the last successful run.

Please see the details in the extracted log below.

How to solve Tomcat 302 error problem?

peter_muc — Wed, 11 May 2016 12:02:43 -0400

We try to call an IVY process start link (/ivy/myprocess.ivp?id=213214) by an external application. As response we expect a JSON object.

But it seems that the IVY Tomcat redirect our request (error 302), so we do not get the response back. Does anybody know to solve this problem?

Thanks!

Runtime Exception Handling

Florian Heinrich — Fri, 30 Oct 2015 15:19:35 -0400

Hello ivy-team, is it possible to handle unexpected Exceptions like RuntimeExceptions? For example, we would like to send an email with all exception information to our developer team and display a specific error message. We would like to display this message in the current user dialog (JSF) and not redirect to an other error page. I tried to create a CustomExceptionHandlerFactory and set this class as exception-handler-factory in the faces-config.xml. Doing this in the Project webContent/WEB-INF/faces-config.xml has no effect. Doing this in the Designer webapps/ivy/WEB-INF/faces-config.xml throws a ClassNotFoundException. Could you please explain how to do this or is there a nicer way?

how to override error page in ivy 5.1.6

uyhang — Thu, 13 Aug 2015 06:32:54 -0400

Hi all In new ivy version 5.1.6, is there any way else that we can declare new error page in server (or we just can override it in web.xml file)? Because When we upgrade the project to new ivy 5.1.6, but in application we still use JSP to develop, so when we catch the error, ivy return the error page, but in this ivy, this is returned in JSF page, it conflicts with our way, and make the application have layout error. We catch the error from ajax call, and display all error response body in content of dialog

The confliction could be: - style from the error page - javascript error because the jquery library in that response

Thanks and Best Regards, Hang

Which setting is relevant for avoiding [dialog instance with id ... is not available any more]?

Nikel Weis — Fri, 27 Feb 2015 11:40:24 -0500

We have a timeout which makes dialog instances die after a certain timeout (I think it's 60000 ms). Which setting in the Ivy-Server is relevant to increase the timeout?

Due to the fact that we are able to customize error-messages from > 5.1 we need to increase this (see here).

I've two settings in mind:

connectionTimeout
keepAliveTimeout
