The situation :
upon application start a static svg is loaded from the filesystem. This
is nothing more then a colored rect, the root element has viewbox like 0
0 800 600

What i am doing :
upon rect-click, retrieve path elements from server and add them to the
document for display. The path elements have coordinates in a specific
viewbox, this viewbox is transmitted from the server as well. Before i
add the elements i modify the viewBox attr of the root element with the
new viewBox.
When i now resize the canvas the path elements briefly show the correct
new position, then the canvas shows nothing anymore.

What does work :
- if i set the correct viewbox in the static svg already, then the
canvas still shows my path elements after resize. Note that i still
replace the viewbox attribute in the document, i just replace with an
identical viewbox so there are no real changes.

What does not work :
- set viewbox (ie change it), then add elements


I hope this clarifies my situation.

Jorg
