Using hidecolumn method crashing app #300

Closed vipin-singh1 closed 4 years ago

vipin-singh1 commented 4 years ago

I am trying to hide a particular column at a particular index. For that I am using mTableView.hideColumn(0) but it is crashing with NullPointerException. Same thing with hiderow works fine but hidecolumn doesn't. How to hide a particular column from tableview?

Can you share the full stacktrace that you get when calling hideColumn? Which version of the library are you using?

I am using library version 0.8.9 and added the hidecolumn method in the sample application.

MGaetan89 commented 4 years ago

Thanks. In master the stacktrace is a bit different, but I was able to reproduce the issue. I'll submit a fix soon.

MGaetan89 commented 4 years ago

I proposed a fix in #301

vipin-singh1 commented 4 years ago

Thank you, will check it.
