NullPointerException with SuggestionBox

[mrmagoo]

Hi all,

I have a strange problem using the suggestion box that I am not able to solve.

I have the following code on my page:

 <f:view>
 <h:form id="testForm">
 <h:inputText value="#{bean.property}" id="property" />
 <rich:suggestionbox id="suggestion" for="property"
 suggestionAction="#{bean.autocomplete}" ignoreDupResponses="true"
 usingSuggestObjects="true" fetchValue="#{suggest.id}"
 var="suggest" width="200" height="200">
 <h:column>
 <h:outputText value="#{suggest.id}" />
 </h:column>
 <h:column>
 <h:outputText value="#{suggest.text}" />
 </h:column>
 </rich:suggestionbox>
 </h:form>
 </f:view>

Bean is a simple Test class:

public class Bean {
 private String property;

 public Collection<?> autocomplete(Object event) {

 List<SuggestItem> result = new java.util.ArrayList<SuggestItem>();

 result.add(new SuggestItem("1", "Horst"));
 result.add(new SuggestItem("2", "Paul"));

 return result;

 }

 /**
 * @return the property
 */
 public String getProperty() {
 return property;
 }

 /**
 * @param property the property to set
 */
 public void setProperty(String property) {
 this.property = property;
 }
}

Everything is fine and it pops up the suggestion box as soon as I start typing.

My goal is to immitate a combo box as I saw at
http://livedemo.exadel.com/richfaces-demo/richfaces/suggestionBox.jsf?c=suggestionBox&tab=usage

So I added a shmall graphic right after the input field:

 <h:inputText value="#{bean.property}" id="property" />
 <h:graphicImage value="cmb-down.png"
 onclick="#{rich:component('suggestion')}.callSuggestion(true)"/>
 <rich:suggestionbox id="suggestion" for="property"
...

Now, when I start typing I get a NullPointerException. I could verify that my method autocomplete gets called.

The same thing happens if I simply do an alert in the onclick event using the rich:component fragment. Doing an alert('Hi') in the onclick results in a popup of the suggestionbox.

I even tried to update to richfaces-ui-3.2.2.SR1 had the same effect.

I am using JBoss 4.2.2.GA.

Any help is welcome.

could you please provide sample war file.. We've tried the same code in almost all possible configs.. jsp, facelets, on tomcat, jboss.. And still can't reproduce :(

[mrmagoo]

Hi,

I sent you an email with my eclipse project.
Hope this helps to find the error.

[ilya_shaikovsky]

thanks for your efforts. will be investigated.

https://jira.jboss.org/jira/browse/RF-4926

[mrmagoo]

Well, it would be good to have a solution here.

I continued with my investigation of the problem. My autocomplete method is called twice. The first time with the entered value, the second time with a null value.

The log says

[ilya_shaikovsky]

also a a temporary workaround please try to define usingSuggestionObjects to false.

Hi Ilya,

unfortunately this did not help.

The difference is: My autocomplete method is called only once.

I added a log to see what happens on the browser side. This is what I get with usingSuggestObjects=false

I typed the letter 'a' in both cases.

Hi,

Please take a look here: http://www.jboss.com/index.html?module=bb&op=viewtopic&t=144620&postdays=0&postorder=asc&start=10

[mrmagoo]

I tried the workaround as it is described in the referred post.

I get the same error:

javax.servlet.ServletException: /index.jsp(28,73) '#{rich:component('suggestion')}.callSuggestion(true)' Function 'rich:component' not found
 javax.faces.webapp.FacesServlet.service(FacesServlet.java:256)

 org.ajax4jsf.webapp.BaseFilter.doFilter(BaseFilter.java:507)
 org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96)

This is comparable to what the author of that posting said. Unfortunately I am not able to follow his solution:

My solution was to combine the new EL-API code with my existing the jbossweb 4.2.3 code.

Any help to understand that would be good.

This is indeed a JBoss bug as it is already mentioned in the other thread. I tested with the new JBoss 5.0.0 without any problems.

Unfortunately I have to stick to JBoss 4.2.2.

The following solved my problems:

<f:view>
 <h:form id="testForm">
 <h:inputText value="#{bean.property}" id="property" />
 <h:graphicImage value="cmb-down.png"
 onclick="document.getElementById('testForm:suggestion').component.callSuggestion(true)"/>
 <rich:suggestionbox id="suggestion" for="property"
 suggestionAction="#{bean.autocomplete}"
 usingSuggestObjects="true" fetchValue="#{suggest.id}"
 var="suggest" width="200" height="200" immediate="true">

 </h:column>
 <h:column>
 <h:outputText value="#{suggest.text}" />
 </h:column>
 </rich:suggestionbox>
 </h:form>

The curious thing about it is:
