help customizing resourcebundle

[gnulp]

Is there a way to configure MessageResource instances with desired characteristics ?

e.g. in struts there is a MessageResourceFactory where a special instance of a resourceBundle can be given to the web-fontend perhaps to handle missing keys more elegantly than throwing a MissinResourceException. Is there any possibility within seam/jsf to inject my own "ResourceBundleImplementation" and then use it in the webpage ?

<fmt:setBundle basename="messages"/>
<fmt:message key="a key from my resourcebundle with specific errorhandling"/>
or
<h:outputText value="messages['a key from my resourcebundle with specific errorhandling']"/>

any hint on that is appreciated

thx

<f:loadBundle basename="messages" var="msg"/>


Look at the Issue Tracker demo.

[gnulp]

Tested it with issue-tracker example: I just removed the message-entry home and get a nice errorMessage on the screen:

MISSING: Home :MISSING

afterwards I put the same 2 lines into the booking example:

<f:loadBundle basename="messages" var="msg"/>
...
<h1><h:outputText value="#{msg.Home}"/></h1>

and added the messages.properties file from the issue-tracker demo (again without Home entry !) but the result is a MissingResourceExcception:

23:10:30,296 ERROR [STDERR] 17.02.2006 23:10:30 com.sun.facelets.FaceletViewHandler handleRenderException

Unfortunatelly I can't find the trick to get this nice error-message like in the issue-demo using facelets. Any ideas ?

Thx a lot for help


**** by the way: seam is great ****

[gnulp]

the same happens when you remove e.g. the entry

loginUser=Username

from the store.properties in the dvd-store-demo

again i get an exception instead of a warning that the resource-entry is missing ...

Is it a problem of seam, jsf or faclets ? It seems to be in the renderkit of facelets-implementation

Thx for help ...

[udo.krass]

Look at your deployed war-file.
Are you sure that your properties-files are deployed?

[gnulp]

yes they are ! if I insert the message-key into the properties file I see the correct message

...

[udo.krass]

Hard to say whats going wrong with your webapp.
The exception is in my mind very useful. Your jsp-page cant find the ressource-bundle.
Try to copy a page and the properties-file from the examples and isolate the mistake...

[gnulp]

I know the mistake ! I have removed a property-file-entry for internationalization. The point is that, there shouln't be that exception, but a smooth error-handling - like e.g.:

"missing key entry: UserName" as it is e.g. in the issue-tracker-demo of seam. If you remove any entry from the messages.properties in the issuer-tracker-demo the page doesn't crash with an exception but is handled nicley with an errorhandler.

The problem is - that this nice errorhandling seems to be broken using facelets in combination with seam.
Maybe somebody has an idea to solve that, because I couldn't find a possibility to implement my own errorhandling using seam ...

[gavin.king]

Well, this is really a pure MyFaces question, not related to Seam.
