Suggestion Box bug: Revisit RF-923
----------------------------------

                 Key: RF-4290
                 URL: https://jira.jboss.org/jira/browse/RF-4290
             Project: RichFaces
          Issue Type: Bug
    Affects Versions: 3.2.1
         Environment: JBoss 4.2.2
            Reporter: Brendan Farragher


I have discovered the following suggestion box bug in a different context that has been reported as being fixed by JIRA RF-923:

https://jira.jboss.org/jira/browse/RF-923;jsessionid=691170C187DCB362DD9AB95D05F61693

The context is the following:

I have a JSP include that contains a JSF subview and a RF modal panel tag. Within the modal panel tag, I have an HTML table. One of the table cells contains a textfield that has a RF suggestion box tag associated. The drop-down list is displayed after typing, but when a selection is made, the result variable (which is a Hibernate pojo) is not passed to the setter method that I have specified as the target on the f:setPropertyActionListener tag. Through logging messages, I see that the method is fired when a selection event occurs. The problem is that the variable is null, just as the behavior states in the RF-923 bug.

In the example below, the setSuggestionBoxNameLookupResult method is passed a null value when the selection is made from the drop down list.

Here is the JSP that is brought in as a subview to the main JSF JSP page via a JSP include tag:

<%@ taglib uri="http://richfaces.org/rich" prefix="rich"%>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
<%@ taglib uri="http://richfaces.org/a4j" prefix="a4j" %>

        <table id="lookupGrid">
