Now that we have SyntaxError defined in Context we should use it instead of Panicing.

Our environments Panic when a binding has already been declared.

But these can be switched to use the ctx instead.

Hi guys,

I could use your input / feedback on this one.

In case we are using non primitive class configs like "directions":

    static getConfig() {return {
        /**
         * @member {String} className='Neo.plugin.Resizable'
         * @protected
         */
        className: 'Neo.plugin.Resizable',
        /**
         * Directions into which you want to drag => resize
 

I have a idea. Auto create a typescript project by run es4x init with --typescript or -t 。It's not manual copy file by sample.
And “mvnDependencies ” added to the package.json by default. Because a lot of people don't know about it。
If you agree, I can modify this code. ^_^
