Error exception is thrown when HOT is within Angular Material Tab which is inactive (not visible).

Demo: https://hot-tab-demo51.stackblitz.io
Note: HOT is in ‘Second’ tab.

Chrome debug console (F12/Console) shows following:

I did check the topic.
So what’s the solution or workaround for my problem?

Thank you.

4

Can you share the code (I can only see the result)?

Here’s the code: https://stackblitz.com/edit/hot-tab-demo51

It looks like this force validation causes the error. You may try to call validateCells once the second tab is chosen.

I’ll implement some workaround.
Are you guys going to fix it? I can submit a bug report.
Thank you.

Sure. We gather all issue on Github. Do you think that this should be continued here ValidateCells issue · Issue #2268 · handsontable/handsontable · GitHub or we should open a new topic?

It looks like the same issue is triggered by a different condition.
I don’t know whether is’s better to open new issue or re-open existing one. Whatever is more convenient for you guys.
Please let me know if I should open new issue.

Thanks!
