This is not a bug in JSTL, but a peculiarity of how a single quote is interpreted by java.text.MessageFormat. For more details, you may want to check bug reports 4293229 and 4321513 in the java bug database (http://developer.java.sun.com/developer/bugParade). The simple rule is as follows: If there is a {0} placeholder in a message string, single quotes have to be doubled. -- Pierre |
A coworker discovered a bug with <fmt:message> that use <fmt:param> parameters. Here is a description of how to produce the bug. make a properties file named test.properties in WEB-INF/classes/test/test.properties. param.key=text before ftm' param {0} text after ftp param In the JSP, use fmt tag to get the corresponding values out. <fmt:setBundle basename="test.test" var="test" scope="request"/> <fmt:message key="param.key" bundle="${test}"> <fmt:param><c:out value="speedy gonzales"/></fmt:param> </fmt:message> what ends up happening is the "'" causes it to not display correctly. If you change "fmt'" to just "fmt", the message will display correctly. Also, if you use two single quotes instead of one, the message will display correctly. When <fmt:message> is used without <fmt:param>, single quotes do not cause a bug and display correctly. peter lin
