SGWT and DHTMLX Scheduler- exception with Date.setHours

[jpappalardo]

I am attempting to integrate dhtmlx scheduler into our smartgwt project and I am having issues. I am wondering if the isomorphic api does something with the js date api that is causing there code to choke on Date.setHours? I tried to attach the external js file in question but it turns out it exceeds your file upload limits. A gnu version can be freely downloaded, or I could email to you if given an email addy. Any help would be greatly appreciated.

We don't do anything to setHours(), and we don't override any functions provided by the browser, but we do extend Date.prototype with additional functions and perhaps we have a naming collision.

You can look at the DHTMLx code (or inspect Date.prototype in a live page) and compare to SmartGWT's Date.js (or again Date.prototype in a live page) to look for collisions.

However, what is also possible and may be more likely is that you are passing Date instances from GWT Java through JSNI to DHTMLx and something is going wrong with this process. Specifically, Date instances created in GWT are from another frame and if passed in the default way, will not have any functions from Date.prototype that DHTMLx may have installed and expects to be there.

Big picture, there are tip-of-the-iceberg issues - integrating a third-party JavaScript component into a GWT application *combined with* integrating it into SmartClient/SmartGWT is a complicated task, and requirements such as accessibility (if you need this) cannot realistically be met. Have you considered Feature Sponsorship as another approach - just have whatever features you need added? We just introduced calendar.showDayLanes, similar to DHTMLx "Multi-Resource View" in 4.1 along with some large performance gains, and another organization is sponsoring a bunch of Timeline and Calendar enhancements for 5.0 that may line up with your needs.
