I'm getting an NPE when using <netui-data:pad> tag inside a repeater tag. 
Here is a repro:

<% pageContext.setAttribute("itemArray", new String[] {"zero", "one", "two", "three", "four"});
%>
<netui-data:repeater dataSource="pageScope.itemArray">
    <netui-data:pad maxRepeat="2"/>
    <netui-data:repeaterItem>
        <netui:label value="${container.item}" />    
    </netui-data:repeaterItem>
</netui-data:repeater>

Expected Result:
zero  one

Actual Error output:
 zero  one  two  three  four
Page Errors
Error Number	Tag Type	Error
1	Pad	Message	An exception occurred when rendering the endTag of the tag "Pad" because: java.lang.NullPointerException
2	Pad	Message	An exception occurred when rendering the endTag of the tag "Pad" because: java.lang.NullPointerException
3	Pad	Message	An exception occurred when rendering the endTag of the tag "Pad" because: java.lang.NullPointerException
4	Pad	Message	An exception occurred when rendering the endTag of the tag "Pad" because: java.lang.NullPointerException
5	Pad	Message	An exception occurred when rendering the endTag of the tag "Pad" because: java.lang.NullPointerException
6	Pad	Message	An exception occurred when rendering the endTag of the tag "Pad" because: java.lang.NullPointerException
7	Pad	Message	An exception occurred when rendering the endTag of the tag "Pad" because: java.lang.NullPointerException
8	Pad	Message	An exception occurred when rendering the endTag of the tag "Pad" because: java.lang.NullPointerException

I'm not seeing any stack traces printed to the Tomcat console.  I get a similar result when
trying to use the 'minRepeat' attribute as well.

I will attach the actual JSP here shortly.
