[Laszlo-dev] bug with optional/rest args in compiler

[Henry Minsky]

I tracked down a  bug I was seeing to this change, if I make the args in
lps/components/base/basebutton.lzx on the "showUp()" method into "...rest"
or "sd=null", then
I get an error at runtime


ERROR @base/basebutton.lzx#212: reference to undefined variable '_enabled'

But if I change the reference from "_enabled" to "this._enabled", then it
works:

        <method name="showUp" args="...rest"> <![CDATA[
            if (!this._enabled && this.disabledResourceNumber) {
           ^^^^^^^^^^^
                this.setResourceNumber( this.disabledResourceNumber );
            } else {
                this.setResourceNumber( this.normalResourceNumber );
            }
        ]]>


So what is it about the optional-args transformation that would be making
the implicit "this" fail in swf8/dhtml?
