Thanks Andrew. As suggested i have placed the snippet right above <h:form>
<f:view>
<t:saveState id="save1" value="#{manufacturerBean.manufacturerList}" />
<h:form id="manufacturerForm">
It results in following exception
javax.faces.el.PropertyNotFoundException: /manufacturerForm.xhtml @23,75
value="#{manufacturerBean.manufacturerList}": Bean:
com.boeing.nmt.nams.view.bean.ManufacturerBean, property: manufacturerList
(no write method for property!)
I didnt understood what does it mean by "no write method for property!" . I
do have getManufacturerList in backing bean
