Hello,
Maybe one of the issue is as presented below ( unfortunately I cannot check
it with MVEL sources but it looks like the reason is the null value of one
of my bean field)
regards
Tomasz
After upgrading 2.3.0 to snapshot( 2.3.1) the error occures on a page which
list the data from the db.
[Click] [error] handleException: java.lang.RuntimeException: [Error: unable
to access field]
