Description

This bug manifests itself when an inputText field is used without a label attribute and is required, for example:

<tr:inputText simple="true" required="true"/>

AND The page also contains a messages tag:

<tr:messages/>

Entering nothing into the field results in a message displayed that the field is required. Entering only whitespace characters results in a null pointer exception:
