<bean:define> tag throws exception when it has a body which may be empty

           Summary: <bean:define> tag throws exception when it has a body
                    which may be empty
           Product: Struts
           Version: 1.1 RC1
          Platform: All
        OS/Version: Other
            Status: NEW
          Severity: Minor
          Priority: Other
         Component: Custom Tags
        AssignedTo: struts-dev@jakarta.apache.org
        ReportedBy: takehiko.yokota@toshiba.co.jp


In the case that <bean:define> tag has a content body which includes
another custom tag, it may throw exception like 'Define tag can contain
only one of name attribute, value attribute, or body content'.

For example, I wrote as follows:

<bean:define id="value" type="java.lang.String"><bean:write name="bean"
property="value"/></bean:define>

When the length of a property "value" of a Bean "bean" is not zero,
the <bean:define> works well, but when the length of "value" is zero,
<bean:define> tag throws exception.

The reason is that <bean:define> considers a zero-length body to be an
empty body.

To avoid this problem, I tried to specify a "value" attribute to the define tag,
but a define tag which has a body content can have neither a name attribute
nor a value attribute. I hope that a define tag which has a content body
also be able to have a "value" attribute, ant it is used on behalf of
a content body when the length of the content body is zero.
