I've tracked down the internal PD error message to the use of a bean within a bean within a bean. For some reason, <html:text> is no longer able to handle the following statement:
<html:text name="regForm" property="user.user.userName" /> It is able to handle: <html:text name="regForm" property="user.userName" /> When using the first line of code the following exception is thrown: java.lang.Error: PropertyDescriptor: internal error while merging PDs: type mismatch between read and write methods at java.beans.PropertyDescriptor.<init>(PropertyDescriptor.java:343) at java.beans.Introspector.processPropertyDescriptors(Introspector.java:649) at java.beans.Introspector.getTargetPropertyInfo(Introspector.java:572) at java.beans.Introspector.getBeanInfo(Introspector.java:372) at java.beans.Introspector.getBeanInfo(Introspector.java:144) at org.apache.commons.beanutils.PropertyUtils.getPropertyDescriptors(PropertyUt ils.java:949) at org.apache.commons.beanutils.PropertyUtils.getPropertyDescriptors(PropertyUt ils.java:979) at org.apache.commons.beanutils.PropertyUtils.getPropertyDescriptor(PropertyUti ls.java:887) at org.apache.commons.beanutils.PropertyUtils.getSimpleProperty(PropertyUtils.j ava:1172) at org.apache.commons.beanutils.PropertyUtils.getNestedProperty(PropertyUtils.j ava:772) at org.apache.commons.beanutils.PropertyUtils.getProperty(PropertyUtils.java:80 1) at org.apache.struts.util.RequestUtils.lookup(RequestUtils.java:952) at org.apache.struts.taglib.html.BaseFieldTag.doStartTag(BaseFieldTag.java:176) at _sharedcontent._registration._register__jsp._jspService(/sharedcontent/regis tration/templates/register.jsp:17) at com.caucho.jsp.JavaPage.service(JavaPage.java:75) at com.caucho.jsp.Page.pageservice(Page.java:555) at com.caucho.server.dispatch.PageFilterChain.doFilter(PageFilterChain.java:155 ) at com.caucho.server.webapp.WebAppFilterChain.doFilter(WebAppFilterChain.java:1 77) at com.caucho.server.dispatch.ServletInvocation.service(ServletInvocation.java: 221) at com.caucho.server.hmux.HmuxRequest.handleRequest(HmuxRequest.java:392) at com.caucho.server.port.TcpConnection.run(TcpConnection.java:315) at com.caucho.util.ThreadPool.runTasks(ThreadPool.java:353) at com.caucho.util.ThreadPool.run(ThreadPool.java:302) at java.lang.Thread.run(Thread.java:534) Has anybody encountered this problem before? I have verified that the accessor methods are returning and accepting the same Object. Does anyone have a suggestion on how to fix this? This code has been running fine for almost 2 years now.
