How to add table actions to an Advanced Table programmatically

Question

We have code in my CO which builds an advanced table dynamically and associates it with a VO. The table comes out looking good - the correct columns and data are displayed.
I now want to add Table Actions for that particular dynamically created table.
The code below builds the buttons correctly and they are built/rendered just fine.
After adding this code to build the FlowLayout bean, add the buttons and associate the it to the TableActions of the advanced table bean, none of the buttons on the page work anymore. Each time I click any button (even if it's a page level button like 'Save' or 'Cancel'), I get the following error:
+## Detail 0 ##+
java.lang.NullPointerException
+     at java.util.Hashtable.get(Hashtable.java:336)+
I have added debug statements in by CO, but it is never even getting into the ProcessFormRequest
Below is the code we are using. Can anyone suggest a way to have this flow layout created dynamically like this and not break all button functionality on the page?
//Create the advanced table
OAAdvancedTableBean tableBeanP1 = (OAAdvancedTableBean)createWebBean(pageContext, ADVANCED_TABLE_BEAN, null,"Proc1Tab");
tableBeanP1.setViewUsageName("P100DetailsVO1");
tableBeanP1.setNumberOfRowsDisplayed(10);
//Create a new flow layout to be used as the table actions
OAFlowLayoutBean tableActionBean = (OAFlowLayoutBean)createWebBean(pageContext, FLOW_LAYOUT_BEAN, null, "P1ButtonRegion");
//Create the "Add Control Group" button for this table:
OAButtonBean addButtonBean = (OAButtonBean)createWebBean(pageContext, BUTTON_BEAN, null, "P1AddCtrlGroup");
FireAction FireActionAddGroup = new FireAction();
FireActionAddGroup.setEvent("AddCtrlGroup");
Parameter param = new Parameter();
param.setKey("ProcedureIndex");
param.setValue("1");
Parameter[] params = {param};
FireActionAddGroup.setParameters(params);
addButtonBean.setPrimaryClientAction(FireActionAddGroup);
addButtonBean.setText("Add Control Group");
tableActionBean.addIndexedChild(addButtonBean);
//Add the table actions bean to the table:
tableBeanP1.setTableActions(tableActionBean);

Hello Ashley,
you are already close to the solution. In BADI QISR1 you simply fill the
table SPECIAL_DATA e.g.like
  fieldindex = 1
  fieldname = 'FIELD1'
  fieldvalue = 'Value1'
  fieldindex = <n>
  fieldname = 'FIELD1'
  fieldvalue = 'VALUE<n>'
Then on the Adobe form layout (Adobe Designer), you have to use the table control XFO from the standard library. Here you have to bind then the corresponding column to FIELD1.
Best regards,
