OpenLaszlo IDEforLaszlo Eclipse plugin

Syte GMBH has provided an update for IDEforLaszlo plugin to support OpenLaszlo 4.0.10 and OpenLaszlo 3.4. IDEforLaszlo has been stale for quite some time now, and I'm glad that someone has offered their time and effort for this project. I'll be checking it out later.

IDEforLaszlo can be found at http://www.syte.ch/en/laszlo.xml.

Permission denied to call method XMLHttpRequest.open

Problem
When deploying DHTML OpenLaszlo applications in SOLO mode, attempts to fetch datasets results in the following error:

ERROR: uncaught exception: Permission denied to call method XMLHttpRequest.openLFCdhtml-debug.js (line 1421)
uncaught exception: Permission denied to call method XMLHttpRequest.open

Solution
As a security measure, most browsers restrict XMLHttpRequest such that they don't accept XML data if the HTTP response headers are not properly set. To fix this, simply change Content-Type to:
Content-Type: application/xml; charset=UTF-8

__LZgetNodes: p is null in Datapath

I'm creating an IPv4/IPv6 OpenLaszlo widget that can bind to a datapath. I spent hours trying to find out why this.datapath.getNodeText() doesn't work inside <handler name="oninit">, although it works fine inside <method>. I kept getting an error of "p is null in Datapath."

For developers experiencing a similar problem, you might want to check out Laszlonia's entry on his blog. It turns out that I simply had to use <handler name="ondata">.
