validation message is lost for the end user
-------------------------------------------
Key: DOXIA-396
URL: http://jira.codehaus.org/browse/DOXIA-396
Project: Maven Doxia
Issue Type: Bug
Components: Book
Affects Versions: 1.1.3
Environment: windows, mvn2, mvn3
Reporter: Ivica Loncar
When doxia validates invalid configuration file (for example chapter id is
missing) validator adds correct message ("Each chapter has to have an id." ) to
the list of errors.
Unfortunately this helpful message is lost for the end user and all she sees is:
{noformat}

The validation failure message is most helpful and it should be presented to
the user.
