Update Value by AjaxListener

Question

my problem is, that I got two fields. Here is the definition:

       <h:selectOneMenu id="selectSource" update=":relationTableForm:selectObject" value="#{tabDefineRelationTable.sourceId}" style="width: 100%;" required="true" requiredMessage="Source is required">
                <p:ajax listener="#{tabDefineRelationTable.handleSourceChange}"   /> 
                <f:selectItem itemLabel="Select Source" itemValue="0" noSelectionOption="true" />
                <f:selectItems value="#{tabDefineRelationTable.mySources}"
                    update=":createArtifactForm:selectObject"
                    var="source"
                    itemLabel="#{source.s_name}"
                    itemValue="#{source.s_id}" />
            </h:selectOneMenu>
            <h:selectOneMenu id="selectObject" value="#{tabDefineRelationTable.objectId}" style="width: 100%;" required="true" requiredMessage="Object is required" onchange="submit()">
                <f:selectItem itemLabel="first select Source" itemValue="0" noSelectionOption="true" />
                <f:selectItems value="#{tabDefineRelationTable.myObjects}"
                    var="object"
                    itemLabel="#{object.o_name}"
                    itemValue="#{object.o_id}" />
            </h:selectOneMenu>

I want to implement, if I select in my selectSource a field, I update the variable objectId in the backend, and see it in my frontend.

Here is my first try to implement it: Variable definition

private List<Source> mySources;
private List<Objects> myObjects;
private Integer sourceId = 0;
private Integer objectId = 0;

Constructor:

public TabDefineRelationTable (TabLoader parent, List<Source> sources, List<Objects> objects) {
    parentForm = parent;

    mySources = sources;
    myObjects = objects;
}

Listener:

public void handleSourceChange() {
    this.objectId = 0;
    if (sourceId != 0) {
        for (Source curSource : mySources) {
            if (curSource.getS_id() == sourceId) {
                myObjects.clear();
                myObjects.addAll(curSource.getObjects());
            }
        }
    }       
}

Thanks a lot.

Update 1: After I tried the solution to use <p:ajax event="select" update="tabView:relationTableForm:selectObject" listener="#{tabDefineRelationTable.handleSourceChange}" />,

<p:ajax event="select" update=":relationTableForm:selectObject" listener="#{tabDefineRelationTable.handleSourceChange}" /> or

<p:ajax event="select" update=":selectObject" listener="#{tabDefineRelationTable.handleSourceChange}" />.

I got this errormessage:Cannot find component with identifier "tabView:relationTableForm:selectObject" referenced from tabView:relationTableForm:selectSource".

Any other Ideas?

Update 2: update="@([id$=output])" testet this one. Didn't got an error, but the field is also not updated :/

Answer 1

could you try this..

 <p:ajax update="selectObject" listener="#{tabDefineRelationTable.handleSourceChange}"   /> 

Answer 2

The solution was to change the ajax line into <p:ajax update="selectObject" listener="#{tabDefineRelationTable.handleSourceChange}" />

Big thanks to serdar for help!
