最大化MPart时发生异常 [英] Exception when maximizing MPart

问题描述

我正在Eclipse应用程序中创建透视图。现在，为了使用我的观点，我创建了一些共享元素以在不同观点之间共享。其中之一是其中包含一些动态MPart元素的MPartStack。

I'm creating perspectives in my Eclipse application. Now For working with my perspectives I created some shared elements to share between different perspectives. One of them is a MPartStack with some dynamic MPart elements in it.

当我双击MPartStack中的MPart时，出现了一些与MinMax相关的奇怪错误。添加在。但是我想在我的应用程序中具有最小最大行为。共享MPartStack中的所有MPart都有此问题。普通MPartStack中的其他MPart我可以最小化和最大化而不会出现任何问题（不会最小化共享的MPartStack）。

When I double click on a MPart that is in the MPartStack I got some strange error related to the MinMax addon. But I want to have the min max behavior in my application. All the MParts that are in the share MPartStack has this problem. Other MParts that are in normal MPartStacks I can minimize and maximize without any problem (only the shared MPartStack will not be minimized).

有人知道如何解决此问题，所以我的用户通常可以最小化和最大化堆栈？

Someone any idea how to fix this issue so that my users can normally minimize and maximize stacks?

我的完整堆栈跟踪：

推荐答案

我发现问题与他们建议使用MArea-> MPartStack结构作为共享元素，而不是仅使用MPartStack。

I found out that the problem was identical to an known issue in Eclispe RCP.

直接使用Part Stack不是一个好主意，它包含一些错误。

They suggested to use a MArea -> MPartStack structure as a shared element instead of only a MPartStack. Directly use Part Stack is not a good idea and contains some errors.
