RE: Javacsript module problem

Take a look at the page source in the browser. Tapestry 5.4 loads modules at the end of the page.

A sample of the tapestry way (what I know) to load shim:
In AppModule.java
@Contribute(ModuleManager.class)
public static void setupMyBaseModules(MappedConfiguration<String, Object> configuration,
                                      @Path("META-INF/assets/jacillacore/highcharts/highcharts.src.js") Resource highchartsSrc,
                                      @Path("META-INF/assets/jacillacore/highcharts/highcharts-more.src.js") Resource highchartsMoreSrc) {
    configuration.add("highcharts", new JavaScriptModuleConfiguration(highchartsSrc));
    configuration.add("highchartsMore", new JavaScriptModuleConfiguration(highchartsMoreSrc).dependsOn("highcharts"));
}

I would recommend to use AMD modules instead of inline javascript.

Hi Cezary,

first thanks. Yes, it was a mixture of all that, meanwhile I studied the
requirejs documentation strongly and checked out the tapestry5-jquery
project, to learn from it.

And now a lot of things are already working!

A lot in requirejs and AMD semms to be magical and I prefer to do java
coding, but we'll never stop to learn...

Regards, Erich
