Hi, I'm using the setup described below (was unable to add it as an attachment via the beta forums). Activated a JavaScript support for my PyDev project, because I have some JS code there, then added Firefox Browser Support Library.
But still I'm experiencing Problems I'm unable to solve while developing a special kiosk app for single browser. I'd be happy with merely masking these errors, but I couldn't find that options as I don't want to turn off entire error classes.
I'm not very strong in JS so I'll appreciate a point to where the code is wrong.
"event cannot be resolved"
Line:
<body onmousedown="event.preventDefault()"> <!-- disables image dragging in Firefox -->
"style cannot be resolved or is not a field"
Line:
(<span style="color: blue; cursor: pointer;" onclick="var s=document.getElementById('debugQueryTable').style;s.display=s.display=='none'?'':'none';this.innerHTML=this.innerHTML=='Show'?'Hide':'Show'">Show</span>)
"options cannot be resolved or is not a field"
Line (looking for the <select> element):
var o = document.getElementById('id_publisher').options;
Thanks for any hints.

The first error, about event being undefined, I'm not sure about.
Where's that defined?
For the last two errors, Document#getElementById() isn't properly
supported yet by the JavaScript validation inside of web pages. The
returned "type" is supposed to vary based on which kind of element
that ID was associated, but we won't have that HTML DOM integration
until WTP 3.2 at the earliest.

Unfortunately, no. It's a real bug/problem in that validator that
we're hoping to address in the next release.
