> Hello all,
> The Eclipse Code Generator Plugin Version 1.2 generates some bad code when making a wsdl
to java. In generated types there is a pieces of code like that:
> protected double localDoubleNumber ;
> // [...]
> protected boolean localDoubleNumberTracker = false ;
> // [...]
> public void setDoubleNumber(double param){
>     // setting primitive attribute tracker to true
>     if (param==java.lang.Double.NaN) {
>         localDoubleNumberTracker = false;
>     } else {
>     localDoubleNumberTracker = true;
> }
> this.localDoubleNumber=param;
> }
> WRONG: param==java.lang.Double.NaN
> isn't allowed because a compare (==) with NaN is everytime resulting FALSE (take a look
here: http://www.concentric.net/~Ttwang/tech/javafloat.htm)
> The result of that bug is, that all elements are tracked, even if they have no value
> RIGHT: java.lang.Double.isNAN(param)
> Greetings, Christophe Denis
