I have created a custom object (Template_Information__c)  with rich text custom field (RichTextArea__c). I am reading the rich text in my vf page as follows:

<apex:page id="pageid" controller="SelectTemplateController">

     <!-- Add the javascript file to intialize the CkEditor -->
     <apex:includescript value="{!URLFOR($Resource.CkEditor, 'ckeditor/ckeditor.js')}" />

     <apex:form id="formid">

    <apex:commandButton action="{!redirectToTemplate}" value="Go to template" reRender="rich"/>

    <apex:inputTextarea id="inputid" value="{!templateInfo.RichTextArea__c}" styleClass="ckeditor" richText="false"/>

      </apex:form>

</apex:page>

At the controller side:

public with sharing class SelectTemplateController {

public Template_Information__c templateInfo {get; set;}

public SelectTemplateController() {
templateInfo = new Template_Information__c();

}

public Pagereference redirectToTemplate() {

insert templateInfo;
System.debug('OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO templateInfo.Id : ' + templateInfo.Id);
}

}

The issue is, the object is saved but when I do a query to fetch the RichTextArea__c it returns null. 

From what I have seen, this issue is due to the ckeditor. If I remove the styleClass="ckeditor" from the inputtextarea tag, the entered content is saved properly. 

Has anyone worked with the ckeditor before? 

I do not understand whay the content from the editor does not get saved in the rich text custom field.

Thanks.
