passing value from selectOneMenu

[boki]

Hi all,
I am trying to use selectOneMenu to pass an id back to my action. That id will then be used to look up an entity and associate it to another entity.

<h:selectOneMenu id="categories"required="true">
   <s:selectItems value="#{prodManager.allCategories}" var="category" label="#{category.name}" />
</h:selectOneMenu>

prodManager has a selectedId that is used to link a Product to a Category.
What is the proper way to pass

#{category.catId}

to prodManager as selectedId?

<h:selectOneMenu id="categories"required="true" value="#{prodManager.selectedId}">
   <s:selectItems value="#{prodManager.allCategories}" var="category" label="#{category.name}" itemValue="#{category.catId}" />
</h:selectOneMenu>

And, take a look at <s:convertEntity />

Thanks, Pete.
Is there a way to simply pass that id w/o convertEntity? In case of convertEntity, I believe I would need to use TransactionalSeamPhaseListener, right? For now, I'd like to avoid that.

If you are using Seam 2.0.1 then what I posted will work, otherwise, you are better off using <f:selectItems /> I guess. If you are using Seam2, then you are using Seam Managed Transactions anyway.

Hello Pete

If I try to implement your example, I get this error:

13:32:05,234 WARN  [lifecycle] executePhase(PROCESS_VALIDATIONS 3,com.sun.faces.context.FacesContextImpl@8ce5fe) threw exception
javax.faces.FacesException
at com.sun.faces.lifecycle.ProcessValidationsPhase.execute(ProcessValidationsPhase.java:108)

13:32:05,250 ERROR [ExceptionFilter] exception root cause
java.lang.IllegalArgumentException
        at javax.faces.component.SelectItemsIterator.next(SelectItemsIterator.java:166)

My View:

<h:form>
<h:selectOneMenu id="functions" required="true" value="#{facilityAction.functionID}">
   <s:selectItems value="#{facility.functions}" var="function" label="#{function.functionIndication.labelKey}" itemValue="#{function.ID}" />
</h:selectOneMenu>
<h:commandLink action="#{facilityAction.selectFunction}">Test</h:commandLink>
</h:form>

My Bean:

private String m_FunctionID;

public void selectFunction() {
   System.out.println("Function: " + m_FunctionID);
}
     
public String getFunctionID() {
   return m_FunctionID;
}
     
public void setFunctionID(String p_FunctionID) {
   m_FunctionID = p_FunctionID;
}

What could be the reason for this error?
Any hints? Thank you for helping...

Whole stack trace please.

I implemented Pete's suggestion without any problems, so I can only assume it is something else in your code, but without looking at the stack trace or the whole code it is not easy to see what it may be.

Hello Pete and Bojan

Thank you for answering...
I just get it working now.
It was a mistake in the Bean.
