Hi,
I leveraged the Ajax support in ProjectWonder into my project
recently and have several questions:
1. It will automatically include prototype + scriptaculous in the
header of output html. However, my html have jquery included, and
they will conflict! The $()
have different semantics in jquery and prototype. Using the
AjaxUpdatingArea will render my existing javascript useless. (Say, $
('#id') no longer find the correct element.) Is re-writing all my
javascript with prototype + scriptaculous the only way I can fix that?
I'd see if jquery can be configured to use a different symbol. The $
is used extensively throughout the JS that Wonder uses.
2. This question is not about ProjectWonder. I want to have my WO
app look consistent without copy-n-paste html code on each page, so
I make a component like this:
Template.html
================================
<html>
<head>
// other css and js stuff
<title><webobject name="Title" /></title>
</head>
<body>
// page structure
<webobject name="Content" />
</body>
</html>
================================
Template.wod
================================
Content: WOComponentContent {}
Title: WOString { value = title; }
================================
In each page, I could simply write
<webobject name="Template">
// This page's content here
</webobject>
My problem is, using this method, I can't break my css into little
part and assign to corresponding page. How will you solve this
problem?
I try to avoid page specific CSS. You could add a <webobject
name="CSS"/> tag to your template and pass in the CSS string on the
pages that use the template.
3. I found the examples come with Xcode / ProjectWonder is hard to
run for a newbie. I can't get any example running until I saw this
screencast:
http://www.wocommunity.org/podcasts/WO54_Examples.mov
Unfortunately, most of the example except the HelloWorld still can't
run. Eclipse whining:
Caused by: java.lang.IllegalStateException:
<com.webobjects.foundation.NSBundle> warning: There is already a
unique instance for Bundle named 'JavaWOExtensions'. Use
NSBundle.bundleForName(JavaWOExtensions) to access it:
<com.webobjects.foundation.NSBundle name:'JavaWOExtensions'
bundlePath:'/Library/WebObjects/lib/JavaWOExtensions.jar'
packages:'( com.webobjects.woextensions )' 56 classes >
or
Caused by: java.lang.IllegalStateException: Main bundle 'Properties'
file can't be read.
That's very frustrated for a beginner. I mean, why don't Apple make
it right at the first time? Examples are very useful for a beginner
comparing to javadocs. We can't run the example by simply click the
build and run button with standard installation, what's wrong with
that?
This is your mistake. Somehow you have created the project so that
the WO frameworks appear more than once on the command line. Do you
have it installed in more than one place?
