Hello everybody,

alert on the front page:
"Reqest error, status : 500 Internal Server Error Messages: undefined"

and the log file with this:

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

</h:panelGrid>
</h:form>

</f:view>

Beans

public class CustomerResearchBkBean extends BaseHibernateDAO{

public List autocomplete(Object event) {
String pref = event.toString();
//collecting some data that begins with "pref" letters.
List result = findAllCountries(pref);

return result;
}

public List findAllCountries(String pref) {
Query queryObject= null;
try {
String queryString = "select country_name from countries where country_name like '"+pref+"%'";
queryObject = getSession().createSQLQuery(queryString);
} catch (RuntimeException re) {
throw re;
}

return queryObject.list();
}
}

AND


public class CustomerResearchBean {
private String country;

public String getCountry() {
return country;
}

public void setCountry(String country) {
this.country = country;
}

}

Thx for ur help

<rich:suggestionbox for="suggest"
width="100"
height="100"
suggestionAction="#{customerResearchBK.autocomplete}"
var="suggest">
<h:column>
<h:outputText value="#{suggest.text}"/>
</h:column>
</rich:suggestionbox>

This means that autocomplete returns a list of objects and object has a property 'text' . However, I do not see that is true. No 'text' property. This is exactly what error message speak about.

Thx a lot Sergey.
You write text property is not defined in any bean witch I use.

That just because I misunderstood the principle of suggestbox mechanism.(the List returned by .autocomplet method HAVE TO BE NOT a simple string(readed by text -getText()-method) list but a list of CustomerResearchBean)


Well, now everything is ok
Thx again

[aviking]

Sorry : "You write" have to be "You right"

[sergeysmirnov]

the principle of suggestbox mechanism is the same standard h:dataTable has. Just 'suggestionAction' works role of 'value' attribute. So,you will face the same problem trying to output result of your query with h:dataTable.
