jsf - Updating column values in PrimeFaces datatable -


i have datatable contains items quoted on, , has columns quantity, unit price, etc , want display total price item when unit price entered. code looks this:

<p:column styleclass="tdasheader" style="text-align:center" width="80" headertext="unit price">     <pe:inputnumber id="unitprice" value="#{quoteditem.quotedprice}"         minvalue="0.01" maxvalue="999999999.99" decimalplaces="2"         style="text-align: right;" size="10">          <p:ajax event="change"             listener="#{supplierquotationbean.onamountchange}"             process="@this" update="totalprice" />          <f:attribute name="quoteditem" value="#{quoteditem}" />     </pe:inputnumber> </p:column> <p:column styleclass="tdasheader" style="text-align:center" width="60" headertext="disc" footertext="total (inc dly)">     <pe:inputnumber id="discount" value="#{quoteditem.quoteddiscount}"                             minvalue="1" maxvalue="100" /> </p:column> <p:column styleclass="tdasheader" width="80" id="totalpricecol">     <f:facet name="header" style="text-align:center">         <h:outputtext value="total" />     </f:facet>     <p:outputpanel id="totalprice" style="text-align:right; padding-right:10px">         <h:outputtext value="#{quoteditem.totalprice}">             <f:convertnumber pattern="#,##0.00"/>         </h:outputtext>     </p:outputpanel>     <f:facet name="footer">         <p:outputpanel style="text-align:right; padding-right:10px">             <h:outputtext value="x#{supplierquotationbean.quotationtotalasstring}x" />         </p:outputpanel>     </f:facet> </p:column>

as may have guessed i'm posting help, ajax update doesn't work - well, works first row only. i've tried changing value in update parameter "#{p:component('totalprice')}" same thing. i've tried using listener update follows:

string clientid = event.getcomponent().getclientid(); string totalpriceclientid = clientid.substring(0, clientid.lastindexof(":"))+":totalprice"; requestcontext requestcontext = requestcontext.getcurrentinstance(); requestcontext.update(totalpriceclientid);

... doesn't work either. more guess, if update whole datatable still same result, additionally lose value in unit price field (even process="@this")!

can please suggest how might able overcome problem?

i'm using primefaces 5.1.15 , myfaces 2.2.6.

many thanks, neil
