Class attribute not escaped in Live Tables

Using the LiveTable Macro to display an object attribute named "where" in a column results in an error, if that column is to be displayed in the first position.

Example:

#set($columns = ["where", "doc.title", [...], "doc.creationDate", "_actions"])
[...]
#livetable("test" $columns $columnsProperties $options)

Results in an "ERROR unexpected token: where" (and the table remains empty), whereas

#set($columns = ["doc.title", "where", [...], "doc.creationDate", "_actions"])
[...]
#livetable("test" $columns $columnsProperties $options)

seems to work without a problem.
