Expression Language jspx

I've read some topics about El and complex expressions but i have not get a solution yet.

I'm trying to get a value of a file in a jspx and it works fine with any of this EL expressions:
"#{TWF_MESSAGES.messages['comun.pruebas']}" // a literal
"#{TWF_MESSAGES.messages[]}" // a bean attribute

The problem is that I've tried to concat them like:



value='${TWF_MESSAGES.messages["menu.funcional.check. +]}'

without success (i've tried more combinations but I can't mix both conditions...)

I know that it can be done in the bean, but i want to get it in the jspx.

Any idea?
Thanks in advance!

More like:

However, as a general rule, complex EL isn't recommended. It makes maintenance more difficult, tends to be hard to read - and to develop, and you don't get the benefits of compile-time checking that you do when using Java backing beans.

So a preferable way to do what you want is more like

and put the message logic in the "getNameMessage()" method of "myBean.

Customer surveys are for companies who didn't pay proper attention to begin with.
It is sorta covered in the JavaRanch Style Guide.
