Java NullPointerException when dragging chart too much to left

GanttProject Desktop Support
#1

On w10Pro, GanttProject 3.005, Spanish. Dual monitor.
Dragging a chart with the “hand icon” to the limits of the destop, to the left (scrolling right : )… would lead to a “NullPointerException”.

I paste the registry log:

#2

Can you please record a screencast showing how this can be reproduced?

#3

It might help to reproduce if the Gantt project has tasks showing data (as dates, in the options), on the left of the task bar in the Gantt chart.

Or if this is not easy to reproduce, then it might be my project data, which is something to start worrying about… : /

#4

The log indicates that NullPointerException is thrown from the internals of the standard user interface libraries. This might depend on the very specific setup and usage pattern, that’s why I want to see the video.

#5

Hello! Might it be to have a videoconference and show it to you?

#6

Well Dmitry… I cannot reproduce the error with the same file and removing some tasks.
It might be something on the data of the project, I think.
When I remove tasks and subtasks of the same project, the error does not appear.

Thank you for your insight on the cause of the error.
