My only concern is with
/tapestry-core/src/main/preprocessed-coffeescript/org/apache/tapestry5/t5-core-dom.coffee
+#if jquery
+ value = $(element).data(attribute)
+#elseif prototype
+ value = JSON.parse($(element).readAttribute('data-' + attribute))
+ if value isnt null
+ value = JSON.parse(value)
+ else
+ value = {}
+#endif
What happens when not jquery neither prototype is used.Instead it should
use the dom api.
Shall i post this to the issue itself?
