Primefaces DataTable Field Specific and Global Filtering Issues

[Eric Bresie]

I am working with Primefaces Datatables with global and field specific filtering (based on the showcase dataset filter example) but am having filter issues. I have enabled pagination and selection capabilities on the datatable

I populate the table with all available items, have a list for selected and list for filtered items.

I am able to filter from the field specific field initially, but subsequent attempts in the same specific field seem to no longer work.

It seems like there may be an update on the filter field value which is not properly triggering the filter of the widget.filter() correctly or updating the bind bean attribute
.
The Global filter also does not appear to function at all.

<ui:composition> <div id="Dsselector"> <h:form id="dataForm"> <p:dataTable id="dataTable" widgetVar="dsTable" var="ds" value="#{dsPageBean.availableDss}" filteredValue="#{dsPageBean.filteredDss}" emptyMessage="No data" rowKey="#{ds.dsId}" selection="#{dsPageBean.selectedDss}" selectionMode="multiple" filterEvent="keyup" paginator="true" rows="20" paginatorTemplate="{CurrentPageReport} {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}" > <f:facet name="header"> <p:outputPanel> <h:outputText value="Search:" /> <p:inputText id="globalFilter" onkeyup="dsTable.filter();" style="width:150px" /> </p:outputPanel> </f:facet> <!-- Hidden id field--> <p:column id="dsIdColumn" filterBy="#{ds.dsId}" headerText="ds" filterMatchMode="contains" sortBy="#{ds.dsId}" style="display: none"> <h:outputText value="#{ds.dsId}" /> </p:column> <p:column id="someDataColumn" filterBy="#{ds.someData}" headerText="Some Data" filterMatchMode="contains" sortBy="#{ds.someData}"> <h:outputText value="#{ds.someData}" /> </p:column> <p:column id="descriptionColumn" filterBy="#{ds.dsDescription}" headerText="Description" filterMatchMode="contains" sortBy="#{ds.dsDescription}"> <h:outputText value="#{ds.dsDescription}" /> </p:column> </p:dataTable> <p:poll interval="60" listener="#{dsPageBean.refreshDss}" update="dataTable" /> </h:form> </div> </ui:composition>

The Page Bean looks like:

@ManagedBean
@SessionScoped
public class DsPageBean implements Serializable {
	private List<Dataset> availableDss = null;
	private List<Dataset> selectedDss = null;
	private List<Dataset> filteredDss = null;
	private List<String> selectedDss = null;

	// getters/setters	
	public List<Dataset> getAvailableDss() {
		if (availableDss == null ) {
			availableDss = loadDss();
		}
		return availableDss;
	}

	// update filtered data on the server side
	public void filterDatasets() {
		List<Dataset> availableDss = getAvailableDss();
		List<Dataset> filteredDss = new ArrayList<Dataset>();

		// server side filter logic ..

		this.filteredDss = filteredDss;
	}

	// periodically refresh data should new items be added
	public void refreshDss() {
		availableDss = loadDatasets();
	}	
}

Dataset class is basic POJO with attributes used in the table.

I suspect I maybe missing a needed attribute (i.e. update, render, ???) but did not see anything like that in the showcase version so am a little confused.

I have tried adding p:ajax event handlers like:

<p ajax event="filter" update=":dataForm:dataTable" oncomplete="dsTable.filter();" />

but this does not appear to do anything to help.

Any ideas?

Environment is Primefaces 3.5 on Mojarra 2.0.11 on WebLogic 10.0

Partial solution...

I remove the pagination and selection options, it seems to start working. I was able to re-enable the selection, so it appears to be related to pagination.

However, pagination is still needed. Anyone have any thoughts?
