Getting 2 rows of data when pasting to one row in Chrome.

[nicam]

Hi There

There's an issue in Handsontable when it's used inside an Angular2 application.
When you copy a row and paste it into a different row on Chrome, 2 rows are inserted instead of one.

It only happens when Handsontable is running inside Angular2. I think this is somehow related to ZoneJS since this issue seems also be happening in MeteorJS when the ZoneJS Bundle is used there (awsp/handsontable-meteor#17).

You can reproduce it here: https://valor-software.github.io/ng2-handsontable/

Steps to reproduce:

• Open example page in Chrome (47.0.2526.111)
• Click on a single row
• CMD+C (on Mac)
• Click on a different row (has to be writable)
• CMD+V

Two rows are inserted.

Any idea why ZoneJS might cause this issue on Chrome?

Best regards

Any news on this?

Hi @nicam Handsontable for Angular2 (https://valor-software.github.io/ng2-handsontable/) is not supported by our team. It's an external library wrote by someone else.

But looking into code I saw that they using older version of Handsontable (0.18.0). This bug what you mentioned above I assume that no longer exists in the latest version. You can try to overwrite older version by executing bower install handsontable#0.21.0 but this solution can brake compatibility with ng2-handsontable.

Hi @budnix, the issue still persists with #0.21.0. I'm not using ng2-handsontable. I just posted the ng2-handsontable for you to be able to reproduce it.

I implemented handsontable into my Angular2 application myself. The issue seems to happen as soon as handsontable is running in an Angular2 Application.

Yes you are right. After upgrading (locally) demo to hot v0.21.0 I got the same issue. We need more time to investigate this case.

@budnix ok, thanks for your help :)

This is an issue with Zone.js in Angular2. I have sent a PR and am just waiting for it to be approved.
Another option is I can send a 1 line PR to Handsontable that will fix it.

Thanks for your help. @poxrud could you tell me what 1liner fixed it in handsontable so I can monkey patch it until ZoneJs is updated?

@nicam take a look at my PR #3195.
