Hi,
to simplify working in JS, I want to include the Prototype JS Library in
our project.
Before you tell me, I can use qooxdoo for all the stuff prototype can
do, let me say, I have been using prototype for quite some time now and
I want to keep using it.
The Problem is, as soon as I include it (using an IResource), I get an
JS-error "$ is not a function element = $(element);" in the
Firebug-console and I cannot use prototype.
The strange thing is, when I start my application with
"-Dorg.eclipse.rwt.clientLibraryVariant=DEBUG", the JS-error is gone and
prototype works.
Maybe the minimized qooxdoo-version messes around with $ ?
Any experience with that?
Regards,
Philipp

Hi Philipp,
you could try to include the prototype library without compression:
public final RegisterOptions getOptions() {
return RegisterOptions.VERSION;
}

Hi Ivan,
this does not help.
Maybe I should add, that I declared prototype as an external library,
because I also need it in a custom widget running in an iframe.
So I decided, to add prototype.js as a
org.eclipse.equinox.http.registry.resources and than used the resulting
url in the IResouce as an external library, since I guess when using it
as an internal resource, I cannot access it from within the iframe and I
didn't want to declare it twice.
And from a quick check if declaring as an internal library helps, I can
state that I observe the same behaviour.
Is there any chance to have a look at the minimized version of qooxdoo
from within eclipse, or is it minimized on the fly?
Regards,
Philipp

Hi Philipp,
both debug and standard versions of qooxdoo library used by RAP can be
found in org.eclipse.rap.rwt.q07 bundle:
org.eclipse.rap.rwt.q07\js\qx-debug.js
org.eclipse.rap.rwt.q07\js\qx.js
Best,
Ivan

Hi Philipp,
I guess the problem is that "$" is globally defined in RAP and in
Prototype:
See first line in qx.js and
function $(element) {
if (arguments.length > 1) {
for (var i = 0, elements = [], length = arguments.length; i <
length; i++)
elements.push($(arguments[i]));
return elements;
}
if (Object.isString(element))
element = document.getElementById(element);
return Element.extend(element);
}
in Prototype.
You could try to replace "$" in qx.js with a different char...
That's one of the reasons I prefer strongly typed languages with
namespaces :-)
Regards,
Stefan.

Hi Stefan,
thanks for your comment.
Because I really wouldn't like to go with a custom version of qx.js, I
filed a feature request to change the variable name
(<https://bugs.eclipse.org/bugs/show_bug.cgi?id=319554>)
Is there any chance to get this change? What/who generates the minimized
version?
Regards,
Philipp

Hi Philipp,
the qooxdoo minimized version used by RAP is generated by us (RAP team),
but with the original qooxdoo 0.7.4 tooling (pyton based).
As long as we do it in that way I doubt that we can fix your issue.
BTW for me, using two javascript frameworks together is like using two
antivirus programs on the same computer - the chance to run into
conflict is very high (like your case).
Best,
Ivan

Hi Ivan,
sure you are right about using two frameworks, but in this case I guess
the problem could easily be fixed, by removing the obvious $ variable name.
Why do you think this would not fix my problem? Modifying the
python-script to use something other than $ shouldn't be too hard.

Hi Philipp,
maybe you could try to build qooxdoo yourself:
1. Grab build project from CVS: releng\org.eclipse.rap.qx.build
2. Grab qooxdoo 0.7.4 SDK from
http://sourceforge.net/projects/qooxdoo/files/qooxdoo-legacy /0.7.4/qooxdoo-0.7.4-sdk.zip/download
3. Use build-custom.sh to build your qooxdoo (change TOOL variable to
point to your qooxdoo sdk location).
Best,
Ivan
