Liferay Input Edtior throwing error (__ckeditor.java : 827)

Question

I am new to liferay portlets. I am facing a strange issue with liferay-ui:input-editor. My environment,

• Liferay 6.2 CE
• Maven
• Weblogic 12c

I have a working portlet which have a configuration.jsp for configuring some contents. The portlet works fine if I deploy the portlet using the automatic deployment by copying into liferayAuto folder. But when I deploy the preprocessed manually, I am getting the below error whenever I try to open the configuration. The issue is with liferay-ui:input-editor, as it works fine when I remove the tag. Below is the error.

java.lang.NullPointerException

In __ckeditor.java the line 827 shows this,

doAsGroupId = (Long)request.getAttribute("liferay-ui:input-editor:groupId");}

Any help is much appreciated ...

Adding <liferay-theme:defineObjects /> in configuration.jsp solved the issue.
