Also side question, for the ej-slider can you set the increment step to be <1 e.g. .1 or .01?

Hi Zack, 
Thanks for contacting Syncfusion support. 
Query 1: for the ej-slider can you set the increment step to be <1 e.g. .1 or .01? 
We can achieve your requirement in ejSlider by using incrementStep API. Please refer the below code block 
<ej-slider width="100%" value="0.5" [incrementStep]='increment' [minValue]='minval' [maxValue]='maxval'></ej-slider> 
export class SliderComponent { 
    increment: any; 
    minval: any; 
    constructor() { 
        this.increment = 0.1; 
Based on your requirement we have prepared the sample and it can be available in the below location 
Query2: Cannot set property 'allowCellMerging' of undefined ; ?  
The script error “Cannot set property 'allowCellMerging' of undefined” due to using of Syncfusion Angular 2 component version below v15.1.33 which supports the Angular 2 version 2.0. We suggest you to update Syncfusion components to version 15.1.33. Now the Syncfusion Angular 2 components seamlessly supports Angular 2 version 2.4.0. Run below command to install latest version of ej-angular2 
npm install ej-angular2@15.1.33 --save  
Refer to the updated seed applications, to quick-start with Syncfusion JavaScript Angular 2 components and follow the below documentation link for getting started with seed application.    
Query3: version of zone.js that works with the new version?  
The latest version of Syncfusion Angular 2 components configured with the zone.js v0.7.4.  
Please let us know if you need further assistance on this

this is my package.json with updated syncfusion and angular 2 dependencies. I've run npm outdated to ensure they're up to date and they are. I'm still getting the zone.js error unfortunately along with a zoneawareerror

and removed the ej-angular2 from dependencies leaving a copy only in dev dependencies following the github seed example

Hi Zack, 

We are unable to reproduce the reported issue from zone.js and we have modified the seed application with given npm package configuration. Refer to the below link for the sample. 

If your still facing the issue please share the sample or modified the given sample as issue reproducible.
