The best example for what is happening is demonstrated here. My code is very, very similar to what is used in that link (I based mine off of it).
Load up that site and click the ‘+’ button on the right hand side. You will get an error that states “Error encountered: Cannot convert NaN to .”
I’ve narrowed the problem to the _addRemoveRow function. It seems like something changed recently with how accessing FlexTable properties is done on callbacks. My code and the site I linked were working fine last night. Today, I get the error.
I looked to see if there were any changelog/release notes that could explain this, but came up empty handed.
Any assistance would be greatly appreciated.
It seems that the issue you are experiencing is more likely related to the TAG value as described in my question with an example test code.
It happened +-10 hours ago, we should raise an issue on the issue tracker as Henrique suggested, I planned to do it if no other comments come in the next few hours but if it’s really annoying for you please consider to do it sooner 😉
