A fix can probably be made later tonight if you file an issue here:

Hi All,
I'm still having issues with OGNL with the latest OGNL / TAP ( out of SVN)
combination. This simple invocation for example:
ognl:getCell(column,row).fareType.name()+'_icone'
always fails with the following exception
nable to read OGNL expression '<parsed OGNL expression>' of

My guess, is that the HivemindExpressionCompiler can't figure out that the
method needs to be invoked on the component and it fails miserabily. Any
idea of when this can be fixed ?
Thx
