using a datatable's column values as input to the value of the next column

I am using a datatable created from a JPA entity.I need to add a column which will be filled with data from another entity, according to the value of the previous column. I could not map the entities as they are in different datasources.

My solution is: 

<h:dataTable value="#{entity1ManagedBean.mydatalist}">
<h:column id="c1">
            <f:facet name="header">
                <h:outputText id="o1" value="Value1"></h:outputText>
            </f:facet>
            <h:outputText id="value1" value="#{temp.value1}"></h:outputText>
        </h:column>  
        <h:column id="c2">
             <f:facet name="header">
                <h:outputText id="o2" value="Value2"></h:outputText>
            </f:facet>
            <h:outputText id="Value2" value="#{entity2ManagedBean.MapValuesMethod(temp.value1)}"></h:outputText>
        </h:column>

but when i run it i get a javax.el.MethodNotFoundException: Method not found: class entity2ManagedBean.MapValuesMethod(java.lang.String)

When i remove the temp.value1 input from <h:outputText id="Value2" value="#{entity2ManagedBean.MapValuesMethod(temp.value1)}"></h:outputText> and test my MapValuesMethod by setting a String input in the method, it works fine.

So i think the problem is i am not passing the temp.value1 string parameter to the managed bean method. Is this possible somehow?

EDIT:

JSF v2.2, eclipselink, web logic 12c

Managed Bean method:

public String getMapValuesMethod(String value1){
       //value1= "some string" (testing method)   
      return sessionFacade.sessionBeanqueryMethod(value1);     
}

and the session bean method is a simple query.

as I said, when I test the managed bean method by setting value1="some stringvalue" the method returns correct results from the session bean query.

Solution

  • Weblogic 12.2.1.2 supports EL 2.x.--> documentation (https://docs.oracle.com/middleware/1221/wls/NOTES/whatsnew.htm#NOTES558). I changed my ManagedBean function from public String MapValuesMethod(String value1) to public String getMapValuesMethod(String value1) and my .xhtml code from value="#{entity2ManagedBean.MapValuesMethod(temp.value1)}" to value="#{entity2ManagedBean.getMapValuesMethod(temp.value1)}" which solved the problem.
