Merge two Columns into one column while showing data Seperately

Use case scenario:  You may need to show your two column header as well as data into a single ADF Table column. 
Please refer the below image for use case:

ADF has made this use case very simple.

You have just wrap your existing(required) Columns into a single column and its done.

Here is the required code sample:

 <af:column headerText="Emplyee Name"  id="c5" align="center">

          <af:column headerText="First Name" id="c8">

                     <af:outputText value="F_Name #{vs.index+1} " id="ot6"/>

          </af:column>

          <af:column headerText="Last Name" id="c9">

                    <af:outputText value="L_Name #{vs.index+1}" id="ot5"/>

          </af:column>

 </af:column>

Implement selectBooleanRadio in Table Column and show it selected by row selection

Here is use case scenarios:
1. A column with radio button. At a single point of time only one radio button should be shown selected in that column.
2. Selecting the radio button will select that row and vice-versa.

Point no. 1 is achieved by simply drag and drop of selectBooleanRadio component.

 <af:column headerText="Select" id="cs4" rowHeader="true" width="50">       <af:selectBooleanRadio text="" label="Label 1" group="RadioButtons"                                 id="sbr1"/> </af:column>

 Remember to add group="RadioButtons" attribute.

For point no. 2 we have to make a javaScript call.
And here is the required code in jspx or jsff.

  <af:resource type="javascript" source="/js/custom.js"/>

And in custom.js add these Lines.

function rowSelectionListener(evt) {
    var table = evt.getSource();
    var selectedRowKey;
    for (key in table.getSelectedRowKeys()) {
        table.findComponent('sbr1', key).setValue(false);
        selectedRowKey = key;
        break;
    }
    table.findComponent('sbr1', selectedRowKey).setValue(true);
} 

Special thanks for point 2 goes to ADF Goodies.

Clean Adf Table filter without Managed Bean

When you have a Adf filterable table then you may have noticed that the text inside the filter don't clear itself when you navigate to other page . It remains there. There are two ways to clear the filters as far as I know.
1. Setting One of the output text column header true
2. A button with managed bean

Adf table's column property RowHeader is set to true then this column renders as a non filterable column with a Clear All icon which clears all filters and reloads the table

1. Setting a Column which is Output Text type to RowHeader=true

2. Earlier look   RowHeader=false

3. Now with  RowHeader=true
