MessageFormatColumnDecarator fails on a date property when escapeXml=true
-------------------------------------------------------------------------
Key: DISPL-374
URL: http://jira.codehaus.org/browse/DISPL-374
Project: DisplayTag
Type: Bug
Components: Decorators
Versions: 1.1
Reporter: Marco Papini
I've tried to use the 'format' attribute of <display:column> tag to decorate a
date property, but I get the following error in the log and the column remains
unformatted:
ERROR MessageFormatColumnDecorator.decorate(66) | Caught an illegal argument
exception while trying to format an object with pattern {0,date,dd/MM/yyyy},
returning the unformatted value. Object class is {0,date,dd/MM/yyyy}
The problematic column:
<display:column property="inizioValidita" sortable="true" escapeXml="true"
titleKey="fields.inizioValidita" format="{0,date,dd/MM/yyyy}"/>
I've tracked down the problem to the class MessageFormatColumnDecorator, line
62: the columnValue was a String instead of a Date. I think this i caused by
another decorator, EscapeXmlColumnDecorator, that converts to String any Object
it decorates. So I've tried to use escapeXml="false" in the above column tag
and it worked.
I think that MessageFormatColumnDecorator should be the first decorator applied
and the EscapeXmlColumnDecorator the last one to fulfill the Principle of Least
Surprise.
BTW, I've also noticed that 4 tests fails when compiling the sources of 1.1
distribution
