JSF Datatable inside a datatable problems

Question

Hi,
i am having a datatable with 3 rows mapping to a column in the database table..now i have another datatable inside the previous datatable mapping to another column in the database.... i am able to fetch the values from the database and populate in the 2 datatables.my first datatable has one column and it is a component label.my second datatable has 4 columns..a select many checkboxes,a component label,and 2 text fields.
Now the problem comes when i need to save the values that are being entered in the datatable..how do i get the values of the checkbox and the textfields and update in the database.and remember i need to get the values of all the components in both the datatables and update in the database...my JSP code and the backing bean codes are as follows.......pls help me with this problem
JSP Code:
<h:dataTable binding="#{AttributeSelection.uiTable2}" id="dataTable2" rowClasses="form"
value="#{AttributeSelection.arrayDataModel}" var="currentRow1">
<h:column binding="#{AttributeSelection.column5}" id="column5">
<h:outputText binding="#{AttributeSelection.outputText1}" id="outputText1" value=""/>
<f:facet name="header"/>
<h:dataTable binding="#{AttributeSelection.uiTable1}" border="1" headerClass="form_bold"
id="dataTable1" rowClasses="form" value="#{currentRow1['attributes']}" var="currentRow">
<h:column binding="#{AttributeSelection.column1}" id="column1">
<h:selectBooleanCheckbox binding="#{AttributeSelection.checkbox1}" id="checkbox1" value="#{currentRow.checkbox1}"/>
<f:facet name="header"/>
</h:column>
<h:column binding="#{AttributeSelection.column2}" id="column2">
<h:outputText binding="#{AttributeSelection.outputText3}" id="outputText3" value="#{currentRow['name']}"/>
<f:facet name="header">
<h:outputText binding="#{AttributeSelection.outputText4}" id="outputText4"
style="height: 23px; width: 50%" styleClass="form_bold" value="#{currentRow1['category']}"/>
</f:facet>
</h:column>
<h:column binding="#{AttributeSelection.column3}" id="column3">
<h:inputText binding="#{AttributeSelection.textField1}" id="textField1"
style="height: 24px; width: 65%" styleClass="input" value="#{currentRow['defaultMin']}"/>
<f:facet name="header">
<h:outputText binding="#{AttributeSelection.outputText8}" id="outputText8" value="Min"/>
</f:facet>
</h:column>
<h:column binding="#{AttributeSelection.column4}" id="column4">
<h:inputText binding="#{AttributeSelection.textField2}" id="textField2"
style="height: 24px; width: 65%" styleClass="input" value="#{currentRow['defaultMax']}"/>
<f:facet name="header">
