Hi!
Thanks for your hints, nevertheless I'm afraid problem is not solved... I'm
importing js file inside my component as you suggesting:
@Import(stylesheet = "MyComponent.css", library="MyComponent.js")
public class MyComponent {...}
Content of js is following:
function setPosition() {
// set of style changes
}
var db = function decorateBody() {
document.body.setAttribute("onload","setPosition();");
document.body.setAttribute("onScroll","setPosition();");
}
db();
What I get in browser is:
1. Uncaught TypeError: Cannot call method 'setAttribute' of null
This leads me to thought that body element (I'm setting attributes on) is
not existing yet. Am I missing something? I've tried to check other
possibilities of javaScriptSupport, but nothing helped.
Only working solution is to use addScript() as Dmitry suggested, I'm not
very happy with storing flag in request solution, but it is currently best
solution I have.
Best regards
Ladislav

JavaScriptSupport.addSCript() is deprecated in T5.4. In addition, I've
just noticed, he's doing a wrong thing anyway: the call to decorateBody()
should be inside a .js file @Import'ed by the component. Tapestry only
includes each imported .js file once, so decorateBody() will be called
exactly once. Problem solved by doing the right thing. :)
