This issue may apply to other connectors as well, but I have noticied it primarily when dealing with Jira issues. Repro steps: 1) Bring up any JIRA issue in the Mylyn Task Editor 2) Resize the Editor view such that scrolling is required 3) Use two-finger scroll such that the mouse cursor is over a text area or input field while scrolling 4) Notice that the text area or input field 'grabs focus' such that, in the case of a combo box, the value changes; in the case of a textarea, scrolling stops, giving the user a 'stuck' feeling. Workaround: * Use the scrollbar (significant usability degradation compared to the browser) * Be careful never to two-finger scroll over an input widget (hard to do given that the text editor is comprised almost completely of input widgets).
Does that also happen when using a scroll wheel? We made this work on Windows and Gtk but I don't recal if scrolling through editable descriptions ever worked on Mac.
Not sure about the scroll wheel as I don't have one. I'm working with a trackpad only.
Leo, Rob, in case you have a scroll wheel, can you check how that works when scrolling JIRA tasks?
Scroll wheel movement exhibits the same behaviour as 2 finger scrolling. There are definitely some fields in the task editor that capture scroll movement; CCombos and multi-line text widgets (such as the CC: box) are obvious examples.
292319: Form pages get stuck on tables, lists, and text fields created with SWT.WRAP when using scroll wheel. https://bugs.eclipse.org/bugs/show_bug.cgi?id=292319 I had tried to get this addressed in SWT, but they said it's platform behaviour so Mylyn would need to provide its own work-around to address this problem.
Indeed, it's not specific to Mylyn; I just noticed it in the STS Dashboard->Knowledge Base textfields as well. Is a Mylyn-specific workaround reasonable? I find this a really annoying usability issue. I would think anyone on a mac laptop would too, unless they're using the scrollbar, it which case they obviously don't care about efficiency anyway :)
I agree. We already invested in implementing a work-around that works on Gtk and Windows. I am afraid we don't have the resources to support a Mac specific fix. I'll mark this bug helpwanted to indicate that we welcome contributions to resolve this bug.
Created attachment 197989 [details] Scroll through CCombos This patch should fix sticky scrolling upon CCombos on MacOS X Cocoa. Mylyn should also be adding EditorUtil.addScrollListener() to all TreeViewers and TableViewers in the task editor, but the existing code only works for scrolling up, not scrolling down. I don't have a solution for that yet.

Thanks Leo! I have applied the patch to the master. I will keep this open the original problem related to scrolling text fields has not been fixed, yet.
Mylyn has been restructured, and our issue tracking has moved to GitHub [1]. We are closing ~14K Bugzilla issues to give the new team a fresh start. If you feel that this issue is still relevant, please create a new one on GitHub. [1] https://github.com/orgs/eclipse-mylyn
