How to render an element whose id is automatically generated in JSF?

问题

I have primefaces'datatable placed on primefaces tabView..

I m using filtering on it. As new values are updated in the grid, I want to re-render the filters.

The filter id is generated as: tabViewId:ActiveTabIndex:DatatableID:ColumnName_filter.

On value change of input text, I want to re-render the filter.

<p:column width="40">
                    <h:inputText id="vendorInputTxt" value="#{articlePromo.proveedor}"
                        styleClass="inputTextStyle">
                        <f:ajax event="change" render=":categoryTabView:0:promotionDetail_dataTable:vendorColumnHeader_filter"
                            listener="#{promotionDetailManagedBean.onProveedorChange}" />
                    </h:inputText>
                </p:column>

But it gives the error, contains an unknown id ':categoryTabView:0:promotionDetail_dataTable:vendorColumnHeader_filter' - cannot locate it in the context of the component vendorInputTxt

What is the right way to render the filter again?

Thanks, Shikha

try a js call oncomplete to: widget_<dataTableId>.filter(); where the dataTableId is the id given to the dataTable.
