Description

The following template fails to execute in the latest tapestry snapshot

<span jwcid="ognl:getCell(column,row).fareType.name()+'_icone' "/>

The java code of the page defining the method :

public ThreeDPricingElement getCell(int column, int row)

{ return ThreeDPricingElement.test }

ThreeDPricingElement is an enum

and the .page contains the following elements:

<property-specification name="row" type="int" persistent="no"/>

<property-specification name="column" type="int" persistent="no"/>

Tapestry fails evaluating and returns the following error

target is null for method getColumn

org.apache.tapestry.BindingException

Unable to read OGNL expression '<parsed OGNL expression>' of $ThreeDPricing_2135@3c1[ThreeDPricing]: target is null for method getColumn
