How can i call a function in a bean where the bean name is a parameter on another bean.
Something like this (This doesn't work):

#{#{bean1.getBeanName}.functionCall}

Thanks.

You can't "call a function on a bean", but you can invoke getters/setters and action processors indirectly. It's actually quite simple:

#{bean1.beanName.functionCall}

If you had a property named "beanName" in bean1 which was itself a bean with a property or action method named "functionCall", the preceeding code would invoke it. It's all part of the Expression Language (EL).

It is sorta covered in the JavaRanch Style Guide.
