I have a problem with form in combination with calendar field (in combination with dataStore and dataProcessor).

Even if I put a “dateFormat” and a “serverDateFormat” inside, I always get the values in JSON date format. When reloading it tells me “invalid date”. Sure, because it’s not “%Y-%m-%d” anymore.

Anybody knows how to get rid of this?



Known problem, please attach your completed demo


what do you mean with completed demo?
The development I am running in the problem or the dhtmlx files?

I mean, just a workaround would be fine for me.

Best regards

at least I need your version of dhtmlx.js to add a fix and some demo to reproduce the probelm and test a fix

direct link to demo with problem will also good, in this case I will write what to change and you can apply fix yourself, you also can send link to, please include link to this thread


thank you very much.
Since it’s pro-Version, I’ll get in touch by email.

Thanks and best regards
