Restore axes method throws an exception after unzoom

To reproduce the ArrayIndexOutOfBoundsException, following actions have to be done:
Create a chart and e.g. add a line. Then zoom into and afterwards create a custom axis. Now if you unzoom an ArrayIndexOutOfBoundsException will be thrown.
As an attachment I add a code example.

Hello,
I can't reproduce this with TeeChart Java v3.2014.0519 SWT.
What version are you using?

Hi Yeray,
thx for reply.
I use absolutely the same/newest version as you. Maybe you didn't reproduce it in the way I described it.
The code I attached, you should use in the following manner.
1) Start the TeeChart SWT Application by running the attached code.
2) Zoom into the Chart
3) press the button
4!) Zoom out -> ArrayIndexOutOfBoundsException will be thrown
I also debugged the source and on this position the source changed in comparison to the previous teechart version.
Stacktrace:
Code: Select all
java.lang.ArrayIndexOutOfBoundsException: 0

Hello Slix,
Excuse me, I didn't follow the steps correctly.
I could reproduce the problem now so I've added it to the public tracker:

Hi Yeray,
thx for the fix! My question for the moment is, how am I able to download this maintenance release? I can't find it in my download area, it's really urgent.
I hope you can help me.

I'm afraid I can't tell you when the next maintenance release will be published.
However, I see you own the sources so you can apply the fix to the sources yourself.
At Chart.java you'll find a method called restoreScales(AllAxisSavedScales s). Change the line where says (line 1509 in Chart.java):
Code: Select all
for (int i=0; i < axes.getCustom().size(); i++)
For this:
Code: Select all
for (int i=0; i < s.customAxes.length; i++)
