searching using selectOneListbox

[jseanjensen]

I'm trying to modify the search panel on one of my pages using Seam 2.2.1.Final with jboss 5.1.0.GA.  I've copied the generated page so that I can derive functionality without rewriting everything.  I've changed the inputtext box in my search panel to a selectOneListbox and would like to use the selected value in my search.  However I'm getting an error that says:

'regionIdcode' parameter is invalid: Target Unreachable, 'region' returned null on 'org.domain.fair.entity.InvOrgCode'

My OrgCodeList.page.xml file code looks like this:

   <param name="from"/>
   <param name="regionIdcode" value="#{invOrgCodeList.invOrgCode.region.regionId}"/>
   <param name="orgCode" value="#{invOrgCodeList.invOrgCode.orgCode}"/>
   <param name="title" value="#{invOrgCodeList.invOrgCode.title}"/>

My OrgCodeList.xhtml file looks like this:

<s:decorate template="layout/display.xhtml">
        <ui:define name="label">Region:</ui:define>
     <h:selectOneListbox style="color:black"
             value="#{invOrgCodeList.invOrgCode.region}" size="1">
          <s:selectItems value="#{regionList.resultList}"
               itemValue="#{region}" var="region" label="#{region.code}"
               noSelectionLabel="Select One" />
          <s:convertEntity />
     </h:selectOneListbox>
</s:decorate>

My InvOrgCode.java class has these declared with all the appropriate getters and setters.

     private BigDecimal invOrgCodeId;
     private Region region;
     private String fiscalYear;
     private String orgCode;
     private String title;
     private Set<FairUser> fairUsers = new HashSet<FairUser>(0);
     private Set<InvPosition> invPositions = new HashSet<InvPosition>(0);

I'm learning so I don't mind a bit of research but I'm also under a deadline so I need a practical solution as soon as I can work it out.

Hi,

Add This to your components.xml

<component class="Region" name="region" />
<component class="InvOrgCode" name="invOrgCode">
     <property name="region">#{region}</property>
</component>

Thank you for replying.

I've added those to my components.xml and am getting error messages saying that they cannot be resolved to a type.

What would be the purpose of defining these here?  Any suggestion on how I can eliminate the error messages?

[vata2999]

By defining these 2 lines you tell Seam, create a component instance of each Entity and bind it to property of your class which is region , then target is reachable
i guess it's because invOrgCodeList, would you please show the source code of invOrgCodeList

Do you have this method in invOrgCodeList ?

InvOrgCode invOrgCode = new InvOrgCode();

public InvOrgCode getInvOrgCode(){
    return invOrgCode;
}

PS : pay attention to naming convention

[jseanjensen]

I have those methods in my inOrgCodeList.java class as you can see.

@Name("invOrgCodeList")
public class InvOrgCodeList extends EntityQuery<InvOrgCode> {

     private static final String EJBQL = "select invOrgCode from InvOrgCode invOrgCode";

     private static final String[] RESTRICTIONS = {
               "lower(invOrgCode.region.code) like lower(concat(#{invOrgCodeList.invOrgCode.region.code},'%'))",
               "lower(invOrgCode.orgCode) like lower(concat(#{invOrgCodeList.invOrgCode.orgCode},'%'))",
               "lower(invOrgCode.title) like lower(concat(#{invOrgCodeList.invOrgCode.title},'%'))", };

     private InvOrgCode invOrgCode = new InvOrgCode();

     public InvOrgCodeList() {
          setEjbql(EJBQL);
          setRestrictionExpressionStrings(Arrays.asList(RESTRICTIONS));
          setMaxResults(10);
     }

     public InvOrgCode getInvOrgCode() {
          return invOrgCode;
     }
}

I resolved my error (thank you for the hint) and tried this.  Although I didn't get any errors I didn't get filtered results either.  I'm sure someone has done this successfully but I have no idea where to see an example.  Does anyone have an example of a search done with a drop down instead of an inputText?
