Hi all,
after upgrading JDK from 1.3.1 to 1.4.0, the <bean:write> tag throws an
exception under some strange circumstances:
java.lang.Error: PropertyDescriptor: internal error while merging PDs: type mismatch
between read and write methods
at java.beans.PropertyDescriptor.(PropertyDescriptor.java:343)
at java.beans.Introspector.processPropertyDescriptors(Introspector.java:610)

at org.apache.struts.util.RequestUtils.lookup(RequestUtils.java:505)
at org.apache.struts.taglib.bean.WriteTag.doStartTag(WriteTag.java:179)
Note: not all bean:write tags show this behaviour, only some of them.
Did anyone else also run into this problem? Has anyone solved it? How?
Thanks in advance,
Erich
