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" %>
<f:subview id="nameModalWindowSubView">
<rich:modalPanel id="lookupModalPanel" width="500" height="250">
<f:facet name="header">
<h:outputText value="#{msgs.header}"/>
</f:facet>
<table id="lookupGrid">
<tbody>
<tr>
<td scope="row" class="cellInfo">
<h:outputText value="#{msgs.findLabelText}"/>
</td>
<td scope="row" class="cellInfo">
<a4j:region id="findNameRegion">
<h:inputText id="findName"
styleClass="LongInput" maxlength="30" value="#{bean.findName}"/>
<%-- Suggestion box RichFaces tag for name.
Performs name lookup and displays drop down list. --%>
<%-- When a selection is made, several fields
are re-rendered with the selected values. --%>
<%-- NOTE: There is a bug in version 3.1.0
of RichFaces where the --%>
<%-- setPropertyActionListener
target method gets passed a null --%>
<%-- parameter, instead of the
selected DB pojo. An upgrade to version --%>
<%-- 3.2.1 was required to fix it.
RichFaces 3.2 jars are present in the --%>
<%-- WEB-INF/lib folder, to correct
this problem --%>
