Here is the definitions being used:
<definition name="layout" template="/WEB-INF/layout/web.jsp"/>
<definition name="layout.mob" template="/WEB-INF/layout/mob.jsp"/>
<definition name="layout.tab" template="/WEB-INF/layout/tab.jsp"/>
<definition name="REGEXP:home(\.(mob|tab))?" extends="layout{1}">
<put-attribute name="heading" value="Home" />
<put-list-attribute name="body">
<add-attribute value="/WEB-INF/views/home.jsp" />
</put-list-attribute>
</definition>
The above rules match a pattern employed with spring-mobile where views can be
resolved based on (mob)ile/(tab)let/normal , as normal is a fallback it does
not contain a suffix.
I can understand why this fails as the capture {1} does not exist in the found
pattern, instead I'd like it to recognise this and evaluate to an empty string.
Full stack-trace is as follows:

I'd like this definition to match "layout" if "home" is accessed, but
I get an NPE.
Would you mind posting the stacktrace?
