Example 8 with DataTable

use of com.liferay.faces.alloy.component.datatable.DataTable in project liferay-faces-alloy by liferay.

the class DataTableRenderer method encodeMarkupBegin.

@Override
public void encodeMarkupBegin(FacesContext facesContext, UIComponent uiComponent) throws IOException {
    // If the rows attribute has changed since the last render, then reset the first row that is to be displayed
    // back to zero. This takes care of any page number rendering difficulties.

Example 9 with DataTable

use of com.liferay.faces.alloy.component.datatable.DataTable in project liferay-faces-alloy by liferay.

the class DataTableRenderer method encodeClientState.

@Override
public void encodeClientState(FacesContext facesContext, ResponseWriter responseWriter, UIComponent uiComponent) throws IOException {
    // Set the rowIndex to -1 so that the UIData.getClientId(FacesContext) method will return a clientId that does
    // not append the rowIndex. This is necessary to ensure that state saving/restoring will take place correctly,
    // since the state is referenced by the clientId.
    DataTable dataTable = (DataTable) uiComponent;
    dataTable.setRowIndex(-1);
    // Encode the hidden field that contains the client-side state of the selected index.
    String hiddenFieldName = dataTable.getClientId(facesContext).concat("_selectedRowIndexes");
    responseWriter.startElement("input", dataTable);
    responseWriter.writeAttribute("id", hiddenFieldName, null);
    responseWriter.writeAttribute("name", hiddenFieldName, null);
    responseWriter.writeAttribute("type", "hidden", null);
    responseWriter.writeAttribute("value", dataTable.getSelectedRowIndexes(), null);
