I am trying to embed URLs to Node Descriptions but have not find a way to do so yet. Basically I'd like to have the node view show active links, so that when the user click the links it will open a web page as a documentation for the node. The syntax for HTML href does not work. The xml links do not seem to work neither. Any help is appreciated.
This behaviour was intended, because when a web page behind a link was very slow, the whole KNIME GUI was unresponsive until the web page got loaded. Therefore we decided to disable links in the node descriptions and only show the address. Luckily, we have found a way (just two days ago actually), to force an external browser to be opened when a link is clicked. This will be integrated in the upcoming 1.3 release.
