Primefaces autocomplete as a datatable filter - jsf

Question

I can't make it work.
Component is sending only part of what is actually in the input. What event should I use to trigger filtering, what option beside forceSelection is needed to actually force selection:
This what is send from a request
InboundShipmentListForm:datalist:j_idt98_input:Select One...
InboundShipmentListForm:datalist:j_idt104_focus:
InboundShipmentListForm:datalist:j_idt104_input:Select One...
InboundShipmentListForm:datalist:j_idt110_input:p
InboundShipmentListForm:datalist:j_idt110_hinput:p
A unexpected error occured! Message: For input string: "p"
<p:column filterBy="#{item.supplierPlant}"
sortBy="#{item.supplierPlant}"
headerText="#{bundle.ListInboundShipmentTitle_supplierPlant}"
style="width:auto; text-align:center">
<!-- autocomplete -->
<f:facet name="header">
<f:facet name="filter">
<p:autoComplete forceSelection="true" itemValue="#{plant}" converterMessage="Select a value"
onchange="PF('datalist').filter()" dropdown="true"
onkeyup="PF('datalist').filter()"
completeMethod="#{inboundShipmentController.completeSuppliers}"
var="plant" itemLabel="#{plant.plantName}"
converter="plantConverter" a:placeholder="Start typing ..." />
</f:facet>
</f:facet>
<h:outputText value="#{item.supplierPlant.plantName}" />
</p:column>

Answer 1

Propably onkeyup event sends string with incomplete value instead the converted plant.
Try to use p:ajax instead onXX events:
<f:facet name="filter">
<p:autoComplete forceSelection="true" itemValue="#{plant}" converterMessage="Select a value"
completeMethod="#{inboundShipmentController.completeSuppliers}"
var="plant" itemLabel="#{plant.plantName}"
converter="plantConverter" a:placeholder="Start typing ...">
<p:ajax event="itemSelect" onstart="PF('datalist').filter()" />
</p:autocomplete>
</f:facet>
