@ghenadiibatalski I cannot reproduce this one on codenvy.io. Can you perhaps share more details on how to reproduce? I Opened a project with files and folders enough to scroll, then scrolled down to the top and clicked on a file to open. The file opened.

just see the animation attached. It is recorded just now on Ubuntu desktop, Chromium and codenvy.io If it helps, the project was initially created from the nodejs project template but the node_modules folder is generated by npm install.

@ghenadiibatalski thanks

Just tried it with an Angular project. Cannot reproduce.

just tried it with a hello-world nodejs project and have got the same behaviour.... Open folder nodejs-hello-world->node_modules->express->node_modules , scroll a page down with the mouse and click with the mouse on any folder. The cursor jumps to the top.

If i use a keyboard for tree navigation, then the mouse works sporadically.

Could this be a weird CSS rendering issue that is unique to Chrome on Ubuntu that somehow doesn't exist with other Chrome versions?

[ghenadiibatalski]

i don't think. Same issue initially on Win 10 FF and Chrome both latest versions and Codenvy On-Prem.

Project type select can affect the behavior of the project tree. I don't see any specification of PT in your reproduction steps. Did you leave the PT as blank or did you set it to one of the types in the wizard? If you set the project to a javac project type does the issue still exist (I know your project is not java - but curious).

[ghenadiibatalski]

same behaviour for java project cloned from github just now

[TylerJewell]

Just to be explicit - did you go into the Project Type... selector in the Project menu and change the PT? I want to be sure that it's a PT thing and not just the clone of code.

[ghenadiibatalski]

same

[TylerJewell]

Well, huh. Does it happen for you on this particular server (this is 5.0.0 release candidate which has another 150 issues resolved in it). https://codenvy-stg.com/site/login?redirect_url=https%3A%2F%2Fcodenvy-stg.com%2F

[ghenadiibatalski]

same here, scroll view jumps to the first page of the tree, but the cursor is set to the clicked node. so i can navigate further with keys from clicked element.

I am calling it a bug for now and adding in a development team, though only for them to try and offer some additional ideas on what we can activate to try and make this reproducible.

Here are some screen captures. You will notice some items don't cause this jump at certain times depending on state of project explorer tree.

Chrome Version 55.0.2883.87 m (64-bit) windows 10

This is also happening in firefox 50.1.0 windows 10.

I'll take a look on this issue asap.

[natthawute]

I got the same issue on Chrome and Firefox (macOS sierra) but it seems to be fine on Safari.

[vzhukovs]

Confirm. This is a bug, trying to solve it.

issue occured at me probably since one of my keyboard key was stuck
