because int othe table not compute the size of List ?

   
Form the projectController , i have a method: getCollectionProject that
return a List<Project> . 
Each project contains a list of Professor .
SO into the last line i would  show the amount of professor for the project
.

The var item rapresent a project.
project contains a List<Professor> 
if  write "#{item.professors.size()}" for get the amount of professors for
the project valutated form each iteration .


Whi into the last outputText :
   <h:outputText value="#{item.professors.size()} tot projects"/>

it shows only the words tot projects and not show the value of listSize?


--------------------------------

<h:form>
                
<h:outputText value="List"/>

                <h:dataTable value="#{projectController.collectionProject}"
var="item">
                    <h:column>
                        <f:facet name="header">
                            <h:outputText value="Id"/>
                        </f:facet>
                        <h:outputText value="#{item.id}"/>
                    </h:column>
                    <h:column>
                        <f:facet name="header">
                            <h:outputText value="name of project"/>
                        </f:facet>
                        <h:outputText value="#{item.name}"/>
                    </h:column>
                    
                     <h:column>
                        <f:facet name="header">
                            <h:outputText value="numbers of professors"/>
                        </f:facet>
                         <h:outputText value="#{item.professors.size()} tot
projects"/>
                    </h:column>
                   
                      
                </h:dataTable>
            </h:form>
