Unable to create part when showing revision information

Open PyvesB opened this issue 5 years ago • 2 comments

Hello hello!

I've got a Cucumber feature file version controlled using Git. I've enabled revision information by right clicking in the file, Team -> Show Revision Information. The editor ruler then displays commit information for every single line when you hover over the lines number, and in the hover popup you can click on "show revision information" again to open a new editor corresponding to that revision of the file.

When I do so, I get an error message "Unable to create part", with the following stack trace:

Let me know if you need any more information!

You should report the issue to the EGit project

I disagree. The faulty line of code is in the Cucumber project: https://github.com/cucumber/cucumber-eclipse/blob/fe9cff7944f58614d3051ecf611d5e3695c01681/cucumber.eclipse.editor/src/main/java/cucumber/eclipse/editor/editors/Editor.java#L166

Assuming that the editor input is necessarily a file is wrong from the point of view of the Eclipse Platform API. EGit is perfectly allowed to launch a text editor not based on a file.

Therefore reopening.
