Icefaces dateTimeEntry component issue with Chrome Browser

Icefaces calendar component that is having issues when used inside a datatable which is rendered inside another datatable.
May be you come across some javascript error and upon typing some entry in date field and onblur the entry is wiped off.
else you might come across the following script error:

Uncaught TypeError: Cannot call method 'init' of undefined
(anonymous function)
runScripts
doUpdate
response
onComplete
AjaxEngine.req.xmlReq.onreadystatechange

The solution to this issue is copy the following code into your web.xml file and run, surprisingly you don't see this script error.

<context-param>
     <param-name>org.icefaces.mandatoryResourceConfiguration</param-name>
     <param-value>dateTimeEntry</param-value>
</context-param>

This error is mainly due to the ELResolver has multiple interfaces and hence the conflict.

If your using eclipse, try to search for ELResolver class by using Open Type (Ctrl + Shift + t) and check those are declared in your POM file with scope "provided"
Mostly if you see any jar file having ELResolver which is not used in any POM file, remove them or try hard refresh your project

Hope that solves the problem.

If you find any other ways to solve the problem, please post in the comments, so atleast that helps others.
