Hello @aleksandra_budnik
I suspect that those bugs, and other similar ones, still show up in new plugin because they never had anything to do with Rule.js itself. Rather they are faults in the logic in handsontable.formula.js, possibly together with the way rendering is handled in handsontable.full.js.
So I am highly disappointed to learn of your intention not to supply workable formulas with the free version of Handsontable. The last free version of Hot with which Rule.js was supposed to work was 0.14.0, released in April 2015. There were so many bugs and missing features, which later versions have since addressed, that for my part I could not go back to using that.
As supplied now, and for the future, the free version will not come with any formula support which allows Hot to be used as “an Excel-like spreadsheet”. I guess we will have to agree to differ that
formula calculations can be also possible via current callback/method set but with lot more work
constitutes what most people would consider to be a “spreadsheet”.
I do not mean to be rude or disrespectful to your work. You have answered my questions here kindly and helpfully for the free version. But unless I can persuade you & your team to reconsider lack of formula support in the free version — even if it’s just making handsontable.rule.js work correctly when using Rule.js, since your plugin’s advanced features are not required — IMHO you are making a poor decision. Having a quite fundamental feature available in free software, telling people that it will be updated to work properly, and then deciding to move that feature into the paid version only, gives free software a bad reputation. Certainly I would never have adopted Hot, and put in all the work I did, had I known that the current, free version would not come with in-built calculations. If there is any leeway for you people to think again over formula support I would most politely urge you to do so.
Thank you for your time.
