未捕获的类型错误：无法读取 null 的属性“calcOnDemand”

Question

I'm getting this error when I click outside the spreadsheet, after creating a new blank file from the File tab

What is the problem in this?

Thank you for using SpreadJS.
It is difficult to know exactly what is going on based on your description. Do you have a simple code that you can share that replicates the issue.

Just in case, you can set the calcOnDemand option using spread.options.calcOnDemand = false; where spread is the name of your spreadJS instance. Grapecity SpreadJS Team
