Re: ScriptEngineManager throws an Error but works... why?

Hi there...

Sorry for the double post! My first post didnt show up. So i thought it was recognised as spam. I'll be deleting it.

Actually i'm using JSNI for eval a simple fomular. I haven't familiar with this feature. But now it works. What is the pure Java solution this problem? In my search i dind't find a native soloution for evaluating Stings-Formulars.

The thing what i have been curious about was, that the development mode throwed an error but still works on client side.

Hi there and hello to this group! (First Post)

First i have to say gwt changed my programmer-life ;) Thanks for that!

My Question:

I'm using SctriptEngineManager in gwt shared package on client side to evaluate String based Conditions (4>2?) or formulas. Every time GWT executes the code, i receive an error in the development console... It says:
12:13:13.012 [ERROR] [contacts] Line 253: No source code is available for type javax.script.ScriptEngineManager; did you forget to inherit a required module?

For some other modules it simply doesn't work because the code is not applicable for converting into javascript. So far all i need to know - fine.

But ScriptEngineManager throws the same error but works... Not that i don't appreciate this behaviour. But i still want to know why it throws this error?

Can anybody point me the reason? Or a better way to evaluate String based conditions or formulars?

My Code:
        ScriptEngineManager manager = new ScriptEngineManager();
        ScriptEngine engine = manager.getEngineByName("js");   
        Object result = engine.eval("4>3");
        Boolean boolResult = (Boolean)result;
