Hello, I met a stack overflow exception, I have some groups in the diagram surface, each group has some children, I expand and collapse those groups for some times, and move around them with different speed, after some while (maybe several minutes or ten minutes), then the exception occured. The overflow function is FindPath method in AStarPathfinder, please see the attached picture, maybe you can find more information. In my application, when the group is expanding, I will add some child nodes, and create some connections, when the group is collapsing, I will remove those nodes and connections. I will test more, and if I have more information I will tell you. Thanks |

Hello, I make a small project to reproduce this bug, this project is much easier to reproduce it, just run it, and double click one group to expand it. And, in my real project, it is not so easy to reproduce, if I expand and collapse the group for serveral times, the program will become slower and slower, maybe this is also the effect of this issue. thanks, |

Hello jzhou Thanks for the repro project. The AStarPathfinder now has better support for node-grouping scenarios. This update will be available in the next nightly build. Jason Fauchelle |
