ConcurrentModificationException during XYChart.draw() #225

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Separate thread adding points to XYSeries
2. GraphicalView.repaint()
3. ConcurrentModificationException if the other thread adds a point while the 
UI thread is iterating through the range returned by XYSeries.getRange() -- see 
lines 247 and 250 of XYChart.draw()

What version of the product binary library are you using?
1.0.0

Please provide any additional information below.
I think that if XYSeries is going to have all those synchronized methods, it 
would help for the drawing to also happen in a thread-safe manner. If there 
isn't a need to support multi-threaded operation, then perhaps there's no need 
for the XYSeries methods to be synchronized?

In any case I got it to work in this case by adding a synchronized statement in 
XYChart.draw().
