The funny thing is that the component is redrawn correctly first but then everything disappears immediately afer. I'll have a look at that method, thanks.
Well i can "correct" the behaviour by setting a correct viewbox first before i start manipulating the document. The viewbox is set dynamically before any other manipulation, so this could be where the problem lays.
I don't think I follow what works and what doesn't. In the working case you set the viewBox before building the GVT tree? Or is it just where in the dynamic case that you set the viewBox?
If you can summarize working/non-working cases I might have suggestions on what could be the problem.
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.
