looks like that somewhere the dom tree was manipulated outside off the updateManager Thread ?! Is this correct ?!
 
And then something like that can happen ?!
 
java.lang.IllegalStateException: RunnableQueue not started or has exited

Because the UpdateManger died ?
 
Is this correct ?! So if this would be correct i have to search for maniplation of the domtree ?!

Betreff: How to create a RasterImageNode from BufferedImage


Hi,
I wish to create barcodes on the fly from a symbology and data attribute of  
A custom 'barcode' element. I have registerde a BrigeExtension class which extends SVGImageElementBridge
 
It behaves weirdly though.
When I first load squiggle (with my extensions) my barcodes will
not show up unless I have previously loaded an SVG file with an 'image'
element.
 
My approach is simply to base64 encode the barcode and stuff it into the 
xlink:href attr.
 
I decided to try another route and I came across this post 
which says the BufferedImage could be placed in a RasterImageNode
bu I haven't been able to figure out how to do this.
 
Can someone please point me onto the right track.
