values in primefaces edit dialog not getting updated - ajax

Question

I have table Providers.I am displaying the table contents in primefaces datatable and performing create,edit and delete operations on it using Jdbc and Tomcat 7.0.
In the edit dialog there are save and cancel buttons. When I click the cancel button and click on the edit button of another row the values of previous row are getting displayed.
I am getting the following warnings when I click on the cancel button:
com.sun.faces.application.view.FaceletPartialStateManagementStrategy saveDynamicActions
WARNING: Unable to save dynamic action with clientId 'editproviderform:btnCancelProviders' because the UIComponent cannot be found
Providers table structure:
ProviderId,
ProviderFirstName and
ProviderLastName

update=":editproviderform" global="false"/>
<h:form id="editproviderform">
<p:panelGrid columns="2" rendered="#{not empty providersBean.selectedProvider}">
<h:outputLabel for="EdtProviderFirstName" value="ProviderFirstName*:"/>
<p:inputText id="EdtProviderFirstName" value="#{providersBean.selectedProvider.providerFirstName}"
