Question

I want to set something like this in the LazyLoading Datatable , I am not able to use the below code.

<p:dataTable var="studyPlanList" value="#{editBean.lazyModel}"
                paginator="true" rows="10"
                paginatorTemplate="{RowsPerPageDropdown} {FirstPageLink} {PreviousPageLink} {CurrentPageReport} {NextPageLink} {LastPageLink}"
                rowsPerPageTemplate="5,10,15" selectionMode="single"
                selection="#{editBean.selectedStudyPlan}"
                id="studyPlanTable">
            <p:ajax event="rowSelect" listener="#{editBean.onRowSelect}" update=":studyPlanEditForm:display"  >
            </p:ajax> 
            <p:column headerText="StudyPlan" sortBy="#{studyPlanList.name}" filterBy="#{studyPlanList.name}">
            <h:outputText value="#{studyPlanList.name}"/>
            </p:column>
        </p:dataTable>

Instead of p:column , if it is h:link it is working, I want to achieve similar results;Please Help.

This is from the facelet tag documentation on f:setPropertyActionListener:

Register an ActionListener instance on the UIComponent associated with
the closest parent UIComponent custom action

So you need a triggering action to make it work. This could be a h:commandButton or h:commandLink. Here is a quick example:

<h:commandButton action="#{editBean.submitAction}" value="Select">
    <f:setPropertyActionListener target="#{editBean.name}" 
                                 value="#{studyPlanList.name}" />
</h:commandButton>

Since you are using Primefaces, you could take a look at the row selection feature of p:dataTable. Here is an example from the showcase.

UPDATE:

The type of the selection should be the same as the type of your row element. I see from your code that selection="#{editBean.selectedStudyPlan.name}" but it should be

selection="#{editBean.selectedStudyPlan}"
