problem in fetching values,JSF-data table

Question

I'm using JSF 2.0 and trying to display a list of data using a datatable. After my data is fetched I have button in each row, on this button it has to take some of the fields as input parameters and then save it.

<h:dataTable id="dt1" value="#{vendorApp.editQtnList}" var="qList" >
 <h:column>
  <f:facet name="header">
   <h:outputText style=""value="RFQ Number" />
  </f:facet>     
<h:column>
<f:facet name="header"> 
 <h:outputText value="Vendor Number"/>
</f:facet> 
<h:outputText value="#{qList.vendorNumber}"></h:outputText>
</h:column>
<h:column>
<f:facet name="header">
 <h:outputText value="RFQ Date"/>
</f:facet>
<h:outputText value="#{qList.rfqDate}"></h:outputText> 
</h:column>
<h:column> 
<f:facet name="header">
 <h:outputText value=""/>
</f:facet>
<h:inputText id="adComment" value="#{qList.adminComment}"></h:inputText>
</h:column>
<h:column> 
<f:facet name="header">
 <h:outputText value=""/>
</f:facet>
<h:form>
 <h:commandButton id="rejectBtn" value="Reject" action="#{vendorApp.rejectEditQuotation}">
 <f:param name="vendorNum" value="#{qList.vendorNumber}" />
 <f:param name="rfqNum" value="#{qList.rfqNumber}" />
 <f:param name="adComment" value="#{qList.adminComment}" /> 
</h:commandButton></h:form> </h:column> </h:dataTable>

In my above code, editQtnList is the getter method for list which gives a list fetched from database.Now user can click on reject by proving a comment in the text box provided, I have tried this as shown but the value of the comment is not feteched..Need suggestions on this....

Have you tried wrapping your whole table in the form?

All input fields of interest must be placed inside the same form as the submit button.

Rewrite your view as follows:

<h:form>
    <h:dataTable value="#{vendorApp.quotations}" var="quotation">
        ...
        <h:column> 
            <h:inputText value="#{quotation.adminComment}" />
        </h:column>
        <h:column> 
            <h:commandButton value="Reject" action="#{vendorApp.rejectEditQuotation(quotation)}" />
        </h:column>
    </h:dataTable>
</h:form>

with

public void rejectEditQuotation(Quotation quotation) {
    // ...
}

Yes, it is. Based on your question history you're using Java EE 6 / Servlet 3.0 (which comes along with EL 2.2 which supports passing method arguments), so this should work for you. See also stackoverflow.com/questions/4994458/…
