Hello,

I would like to render a component that would be chosen from it's name  
(a String).

Something like:

<t:Delegate to="myComponentName" param1="..." param2="..." />

In the enclosing component I would have:

public String getMyComponentName()

Which returns the name of a component in my project. It would be  
instantiated and the parameters (param1, etc...) would be passed to it.

I would allow to build a page dynamically from data found in a  
database for example:

- if it's a string, put the TextField component, if it's a "choice",  
put the Select component, if it's a xyz, put MySpecialComponent.

I thought it would be possible with Delegate, but I am afraid I didn't  
understand well how to achieve this.

Thanks,

Alex
