Primefaces lazy datatable : how to retrieve the visible list












0















I have a lazydatatable displaying thousands of cars. I ll have a buy button on the top of the page.
Basically, i want the user to buy all the cars visibles on the list when I press on the Buy Button. I m struggling to get a list limited to these cars.



How can I do?



xhtml



 <p:dataTable var="car" value="#{carView.listCars}" paginator="true" rows="10" paginatorTemplate="{RowsPerPageDropdown} {FirstPageLink} {PreviousPageLink} {CurrentPageReport} {NextPageLink}
{LastPageLink}" rowsPerPageTemplate="5,10,15" selectionMode="single" selection="#{carView.selectedCar}" id="carTable" lazy="true">
<p:column headerText="Year">
<h:outputText value="#{car.year}" />
</p:column>

<p:column headerText="Brand">
<h:outputText value="#{car.brand}" />
</p:column>




CarService



public void buy{

...
}


CarView



public void init(){
LazyCarDataModel cars= restService.getCars();
}

          Using a p:datatable in lazy mode, you provide the data for the 'visible' list via the load method in your LazyDataModel. So if you keep that list in one way or another on the server (e.g. storing it in a @Viewscoped bean`), it is available when you click 'buy'.



          Another way is to support multiple selection and have a 'select all' toggle box at the top of the selection. And then use the selected files server side
