to get the multiple selection work, selectedAuthories must be an array :
Authories[] selectedAuthories;

Datatable preselection is not implemented (at least for now)

you can "solve" it by using instead of the selection an extra column with checkboxes,
something like:

Code: Select all

<p:dataTable id="authories" var="authory"  value="#{roleController.authories}" rows="10" paginator="true">
         <p:column>
            <f:facet name="header">
               <h:outputText value="inRole" />
            </f:facet>
            <h:selectBooleanCheckbox id="openDossiers" value="#{authory.inRole}">
               <p:ajax event="click" update="authories"/>
            </h:selectBooleanCheckbox>
         </p:column>
         <p:column>
            <f:facet name="header">
               <h:outputText value="Authory Name" />
            </f:facet>
            <h:outputText value="#{authory.name}"></h:outputText>
         </p:column>
</p:dataTable>

Also you could use JavaScript.

Your DataTable needs a widgetVar. For example:

<p:dataTable widgetVar="yourTable" .... >

Use this JavaScript

yourTable.selectRow(1); //selects row 1
yourTable.selectRow(2); //selects row 2 too
yourTable.selectRow(3); //selects row 3 too

Datatable preselection was implemented if it doesn't work please create an issue. We're pushing all datatable related issues to 2.1.1 as it will introduce new powerful datatable soon.
