generate and execute javascript at runtime?

[Dennis Haupt]

i'm trying to integrate jqxgrid and write a gwt wrapper around it. (it's some jquery grid) i know i can write native js methods, but this isn't enough. i need to dynamically build the call and then execute it as if it was sent from the server inside a script tag. how can i do that?

Hi, is it not possible to make a function like eval() (doing just that) available via JSNI?

i remember there being some magic rules, but i'll try

True, but eval() is one of the Cardinal sins of programming. Think deeply if there is any way around it. But then again, you are the Hamster of Death, so you may be prone to sin.

the reason i am using the GWT is so that i do NOT have use javascript. so obviously, eval seems like totally harmless to me :) what's wrong with it?

It is just a good way to create a security hole and allow for malicious code execution. And it also prevent compiler optimizations since the compiler cannot divine what you're going to run. However, your use case is likely a valid one for eval since you're wrapping a JS lib.
