Hello,

It is not possible to use ${} EL markup inside outer ${} expression. But is it possible to workaround this? What I want to do is to pass a parameter to a EL function, while the parameter itslef is not hardocoded, but is stored in a variable. I have custom fecelet EL function, and a custom tag using this function. I'm passing parameter to a tag, and want to use it as a EL function parameter, but obvoiusly this is not working this way:

page source code:

tag xhtml description
I guess there must be other way to pass in the parameter. Could you suggest something?

Thank you!
Tim

Take a look at <f:param> and I believe you should be able to modify your custom component to support this
