Maria, There is a difference between you rectangle and text examples. The rectangle sets attributes with a 'null' namespace and the text uses the SVG namespace. I've never tried this before but if you are looking for a difference then that is probably it.

I'm working on my Software Engineering thesis, therefore I need to be able to manipulate svg content dynamically. So far I've been able to add shapes to a document, but I'm having trouble adding text... I've debugged it and it looks like the text is actually being added but it is not shown in the SVGCanvas... I'm pasting an example... It would be extremely helpfull if someone could give me a hint of what I'm doing wrong :) Thanks for your time!
