Subject OGNL error in log - Error setting expression
Date Fri, 27 Jul 2012 17:33:36 GMT
I noticed some OGNL warnings in my log that I show below [1].
User scenario:
1) go to form. no warnings
2) submit form - page is reloaded. warnings appear.

The warning is for property which is being used on a key: <s:submit
key="geral.save" />. The key is defined in globalmessages.properties.

It seems the question of whether or not these warnings should appear has
been discussed in the mailing list before. What I couldn't find is this:
should there even be a warning in this case, given that the property
should be searched for in the i18n resources and not the action?


Thank you,

Miguel Almeida
