Never mind... Deleting, then regenerating the BeanInfo class fixed it. Most likely the BeanInfo class somehow got out of sync with the object, and it took deleting it, then regenerating it (and not simply updating it) to fix the problem.

Greetings all... Has anyone ever seen something like this happen? java.lang.NullPointerException at java.beans.Introspector.addMethod(Introspector.java:741) at java.beans.Introspector.getTargetMethodInfo(Introspector.java:705) at java.beans.Introspector.getBeanInfo(Introspector.java:298) at java.beans.Introspector.getBeanInfo(Introspector.java:81) at org.apache.commons.beanutils.PropertyUtils.getPropertyDescriptors(PropertyUt ils.java:925) at org.apache.commons.beanutils.PropertyUtils.getPropertyDescriptors(PropertyUt ils.java:955) at org.apache.commons.beanutils.PropertyUtils.getPropertyDescriptor(PropertyUti ls.java:866) at org.apache.commons.beanutils.PropertyUtils.getSimpleProperty(PropertyUtils.j ava:1148) at org.apache.commons.beanutils.PropertyUtils.getNestedProperty(PropertyUtils.j ava:751) at org.apache.commons.beanutils.PropertyUtils.getProperty(PropertyUtils.java:78 0) at com.ngt.baseframework.presentation.taglib.struts.OptionsTag.processValue(Opt ionsTag.java:449) at com.ngt.baseframework.presentation.taglib.struts.OptionsTag.doEndTag(Options Tag.java:327) Here's some background: - No code has changed... This was working fine this morning!#$@... - Here's the custom tag code (OptionsTag.java) that blows up (in the processValue method): result.append(PropertyUtils.getProperty(element, valueProperty)); result is a StringBuffer of course... So this code works when valueProperty is one value, then it blows up when valueProperty changes and is equal to "title" (i.e. It blows up when it hits the second dropdown). The element object is an instance of an object that has a title attribute, as well as a getter/setter for the attribute. The object even has a corresponding BeanInfo class that contains the following code: ... private static final int PROPERTY_title = 31; ... properties[PROPERTY_title] = new PropertyDescriptor ( "title", AssociateContactBO.class, "getTitle", "setTitle" ); ... >From the stack trace, it looks to me like the BeanInfo class has been retrieved successfully, and a Method object is being added to some collection and maybe this method object can't be found for some reason? I'm not stepping through the code, so I'm just guessing here... Any clever insight would be greatly appreciated, but at this point I'd just be happy if someone pointed out some stupid mistake that I've made. Cheers...
