Creating dynamic message

[jagin]

I want to get a message from application resource boundle in my xhtml in a dynamic way. I thought that it should be possible in this way:

#{messages['myEntity.name.' + myEntity.name]}

(myEntity.name returns string)

but i got

java.lang.NumberFormatException: For input string: "myEntity.name."

Is it somehow possible?

Thanks

Jarek

Jarek,

EL is trying to do math with your strings...pretty silly don't you think? 

Try doing a string concat with a JSF function.  I don't believe JSTL comes with a concat.  However, just follow this suggestion from James Kelly

Yeah, either write a custom EL function, or just use:

#{messages['myEntity.name.'.concat(myEntity.name)]}

[jagin]

#{messages['myEntity.name.'.concat(myEntity.name)]}

Hah, the simplest things are always near the corner ;) Thanks a lot.

Is concat Seam 2? Does not seem to work with 1.2.
