[jexl] dotted property names in expressions

[Ryan Hoegg <rh...@isisnetworks.net>]

Hi,

There is a problem with jexl when testing dotted property names for 
emptiness.  I am using it from jelly through maven:

maven -Ddotted.property.name=foo goal

inside the goal:

<j:if test="${empty(dotted.property.name)}">
  <echo> Empty property </echo>
</j:if>

<j:set var="littlename" value="${dotted.property.name}"/>

<j:if test="${empty(littlename)}">
<echo> Empty little property </echo>
</j:if>

Only the first echo happens.


If I get more time to get the code from CVS working in eclipse and to 
get my head around Jexl internals, I'll write a unit test.

I just added a unit test to the CVS version of jexl, I think it 
exercises this ( and works fine )
