hmm.
Have you run it with firebug or venkman? When I've run into this before it
was usually because the script had a parse error causing the interpreter to
barf and not load the rest of the script.

I'm having a strange problem executing javascript functions from ajax.
Some scripts work and some don't. I've got this java code:
target.appendJavascript
("toggleSelection(document.getElementById
('"+getComponent().getMarkupId()+"'))");
And in the html I've got this:
<wicket:head>
<script type="text/javascript" src="js/reports.js"></script>
</wicket:head>
The function toggleSelection is in reports.js.
If I make toggleSelection just a simple script, it runs fine. But if
I add more code to it, I sometimes get the following error response.
I've verified that reports.js is included in the html source.
INFO:

I've gone through the JS code very carefully to see if there are any
mistakes. I can't find any. Here is the code that causes the error:
function toggleSelection(element) {
var cn = element.parentNode.parentNode.className;
alert(cn);
switch(cn) {
case "odd":
alert("in odd");
element.parentNode.parentNode.className =
"oddSelected";
alert("out odd");
break;
case "oddSelected"):
alert("in oddSelected");
element.parentNode.parentNode.className = "odd";
alert("out oddSelected");
break;
case "even":
alert("in even");
element.parentNode.parentNode.className =
"evenSelected";
alert("out even");
break;
case "evenSelected":
alert("in evenSelected");
element.parentNode.parentNode.className = "even";
alert("out evenSelected");
break;
default:
break;
}
alert("done");
}
I have it working now by using a different toggleSelection script.
Now the output is this:
INFO:
INFO: Initiating Ajax POST request on
/sa/app?wicket:interface=:7:tabs:panel:reportForm:availReport:availRow:4:row:scheduled:-1:IUnversionedBehaviorListener&wicket:behaviorId=0&wicket:ignoreIfNotActive=true&random=

INFO: Response parsed. Now invoking steps...
INFO: Response processed successfully.
INFO: Invoking post-call handler(s)...
And the code is this:
function toggleSelection(element) {
var cn = element.parentNode.parentNode.className;
if (cn == "odd") {
element.parentNode.parentNode.className = "oddScheduled";
}
else if (cn == "oddScheduled") {
element.parentNode.parentNode.className = "odd";
}
else if (cn == "even") {
element.parentNode.parentNode.className =
"evenScheduled";
}
else if (cn == "evenScheduled") {
element.parentNode.parentNode.className = "even";
}
}
What causes that type of Error message in the ajax window? Is it
javascript that doesn't execute properly? Why would it say the method
is undefined? Is there something wrong with that first script? I
realize this isn't a javascript list, but I really don't see anything
wrong with it.
Thanks,
Tauren
