This has to do with an innerHtml line that shows up in jquery.js,
although line 251 in that file is actually blank, so I don't know
where it comes from.
Creating the widget was simple. I just created a class to spit out the
relevant NodeSeqs:
class Container {
def renderHead(xhtml: NodeSeq): NodeSeq = {
head
link rel=stylesheet type=text/css href={/ +
LiftRules.resourceServerPath +/mbContainer.css} title=style
media=screen/
script type=text/javascript src={/ +
LiftRules.resourceServerPath + /mbContainer.js}/script
script type=text/javascript src={/ +
LiftRules.resourceServerPath + /ui.core.min.js}/script
script type=text/javascript src={/ +
LiftRules.resourceServerPath + /ui.draggable.min.js}/script
script type=text/javascript src={/ +
LiftRules.resourceServerPath + /ui.resizable.min.js}/script
script type=text/javascript src={/ +
LiftRules.resourceServerPath + /jquery.metadata.js}/
script
This should be escaped in a ![CDATA[ block:
script type=text/javascript{
Unparsed(
$(function(){
$(.containerPlus).buildContainers({
containment:document,
elementsPath:elements/
});
});
)
}
/script
/head
}
Why is this Unparsed? Why not just use XML?
def renderContainer(xhtml: NodeSeq): NodeSeq = {
Unparsed(
div class=containerPlus resizable {buttons:'m,c',
skin:'white'}
div class=no
div class=ne
div class=nmain content/div
/div
div class=o
div class=e
div class=c
div class=contentThis is
the main content/div
/div
/div
/div
div
div class=so
div class=se
div class=s/div
/div
/div
/div
/div
/div
)
}
If I have to jump through hoops to get it to work in Firefox, what
good is Lift? Or, am I just missing something obvious? If anyone has
had similar problems and has a workaround, please help.
The only problem I've ever had with Firefox is a bug related to attributes
with namespaces.
Please note that Lift serves XHTML and Firefox is very strict about
validating XHTML. Unless you are serving your static page with a mime type
of application/xhtml+xml, you will not trigger Firefox's heightened
validation.
By the way, if I just create an html file with the containerPlus node
as above and display it in Firefox without using Lift, I don't get the
error. Everything works great.

[Lift] Re: Exception thrown in Firefox but not in IE. What Gives????
Dave,
I appreciate your input. I've tried many permutations of code to try
to get this to work. The ![CDATA[ block didn;t work. I even just put
all the code into default.html as-is - no widget at all, no special
parsing involved, and still no luck.
I did get rid of the Firefox error by removing the unparsed stuff.
However, the code still doesn't work because I think it can't find the
elementsPath
elements/. In fact, now it doesn't even work in IE.
This path contains all the images used by the container. I've placed
them in src\main\webapp\elements. Do
I also need to manage this somehow in Boot with ResourceServer.allow
and/or put the images someplace else?
The strange thing is that when I was getting the Firefox error, the
container images worked fine in IE. So it seemed the elementsPath was
OK.
This leads me to believe there is some parsing going on in Lift that I
just don't grasp. But, then again, it's probably something simple.

Please post a simple example that fails on Firefox. I'll clean it up for
you.
