acesMessages.instance().add. EL and params problem

jagin Mar 10, 2008 2:28 PM

I want to add the global message with some params. I use the function

FacesMessages.instance().add("#{messages['myMessage']}", myParam);

in message.properties i have:

myMessage=This is may message with param #0

but i got this message on the browser:

This is may message with param #0

if I change it to:

FacesMessages.instance().add("This is may message with param #0", myParam);

The message is displayed properly.

What is wrong?

Use {0} in your messages.properties.

Cheers,

Damian.

Is messages a resource bundle?

Have you tried using the methods addFromResourceBundleOrDefault() or addFromResourceBundle().

It would look like this:

FacesMessages.instance().addFromResourceBundle("myMessage", myParam);

FacesMessages.instance().addFromResourceBundle("myMessage", myParam);

works well. It looks like
#0 and {0}

are both working. Thanks.

To summarize, i put in my code:

FacesMessages.instance().addFromResourceBundle("myMessage", param); FacesMessages.instance().add("#{messages['myMessage']}", param); FacesMessages.instance().add("Param: #0, {0}", param);

and for
myMessage=Param: #0, {0}

and
int param = 3;

i got this messages:

Param: 3, 3 Param: #0, {0} Param: 3, 3

so it looks like there is something wrong with FacesMessages.instance().add and EL in it.

Yes, there is no support for injecting using EL inside FacesMessages.instance().add(String messageTemplate, Object ... params) - this only works by chance.
