PrimeFaces: how can I dinamically check a p:column?

[otuka]

I have a <p:dataTable> with a <p:column selectionMode="multiple" />. When I have a single row displayed in the dataTable, I want my application to automatically check this row (and also the "checkAll" checkbox displayed on the table header).
I've done this via JavaScript and it visually worked. However, when submitting the form, it seems the "checked" value isn't submitted. If I click on the checkbox twice (to uncheck and check it again), it works.

Code: Select all

<p:dataTable var="invoiceGroup"
             selection="#{chargeBean.selectedInvoiceGroupBeans}"
             value="#{chargeBean.invoiceGroupList}"
             rowKey="#{invoiceGroup.id}">
    <p:column selectionMode="multiple" />
    ...
</p:dataTable>

Code: Select all

function selectTableElements() {
    var checkBoxes = $('#invoiceGroupTable td.ui-selection-column input[type="checkbox"]');
    var paginatorPages = $('#invoiceGroupTable .ui-paginator .ui-paginator-pages .ui-paginator-page'); 
    if (checkBoxes.length === 1 && paginatorPages.length === 1) {
        setTimeout(function () {
            $('#invoiceGroupTable th input[type="checkbox"]').click();
        }, 10);
    }
}

Is there a way of doing this server-side?

             selection="#{chargeBean.selectedInvoiceGroupBeans}"
             value="#{chargeBean.invoiceGroupList}"

    <p:column selectionMode="multiple" />
    ...
</p:dataTable>

I think you can do the following server side (or something similar), or this is what I would do. I like using AJAX to do everything server-side, and honestly, my goal is to do NO javascript at all. Years ago, when I first did HTML/Javascript/server-side coding via Powerbuilder, I fell in love with JavaScript, and tried to do JavaScript as much as possible, but now with Java/J2EE/JSF/PrimeFaces, my goal is to avoid Javascript!!!

This should meet the requirement of the use case you described. I handwritten code below just now; i prefer to copy/paste my code, if I have one similar.

Code: Select all

public <datatype???> getInvoiceGroupList () {
    ...
    if (invoiceGroupList.size() == 1) {
        selectedInvoiceGroupBeans[0] = invoiceGroupList.get(0);
    }
    return invoiceGroupList;
}

It didn't work. When the table gets rendered (after an event), it still shows the checkboxes unchecked.
Debugging, the method getInvoiceGroupList, it successfully sets the array of elements. However, the method getSelectedInvoiceGroupBeans isn't called.

That's what I've done by now:
* with JavaScript, checking the amount of elements. If it's == 1, then check it and disable the uncheck.
* on Server Side, always consider the element checked if the list contains only one element.

Am I doing something wrong? Why isn't the method getSelectedInvoiceGroupBeans() being called?

Please copy/paste your entire bean and xhtml/jsf file, and I'll take a look and advise further.
