Can not do a deletion

Hello

Nice day.

I'm hands-on lab 6 of the course 'R12.x extend Oracle Applications building OA Framework Applications. In turn, we will do a delete, based on a mixer operation if the employee and the end date, that the page should allow a deletion if not delete icon is disabled.

Here is the code that generates the error, if I remove this code, the page will open normally.

--------

Import oracle.cabo.ui.data.DictionaryData;

Import oracle.cabo.ui.data.DataObjectList;

Import oracle.apps.fnd.framework.webui.beans.table.OATableBean;

Import oracle.cabo.ui.data.BoundValue;

This controller is associated with the table.

Table OATableBean = webBean (OATableBean);

You need to format the image to switch column so the image

is centered (this is not done automatically for mixers

as it is for the ordinary image columns). Start by getting the

the table column formats.

NOTE! You must call the prepareForRendering() method on

the table * front * formatting of columns. In addition, the

appeal must be sequenced * after * the table is requested,

and * after * you do any manipulation of control bar.

table.prepareForRendering (pageContext);

DataObjectList columnFormats = table.getColumnFormats ();

ColumnFormat DictionaryData = null;

int childIndex = pageContext.findChildIndex (table, "DeleteSwitcherRN");

columnFormat = (DictionaryData) columnFormats.getItem (childIndex);

columnFormat.put (COLUMN_DATA_FORMAT_KEY, ICON_BUTTON_FORMAT);

Implement the value bound to the Image of the State

OAImageBean = statusImageBean

(OAImageBean) table.findIndexedChildRecursive ("EmpStatus");

If (statusImageBean == null) {}

[] Tokens = MessageToken

{new MessageToken ("parameter", "EmpStatus") ;}}

throw new OAException ("AK", "FWK_TBX_OBJECT_NOT_FOUND", chips);

}

Set the directory of OA Framework images

ImageDirectory = FixedBoundValue

new FixedBoundValue (APPS_MEDIA_DIRECTORY);

Set a binding between the grain of the image and the attribute of VO

It will make reference to get the name of the .gif image value.

Note that the values of the corresponding attributes are obtained using a

Decode() in the view of QueryVO object.

OADataBoundValueViewObject = statusBinding

new OADataBoundValueViewObject (statusImageBean, "EmployeeStatus");

Concatenate to the images directory with the name of the actual image

(as comes from the statement attribute VO decode())

ConcatBoundValue = statusCBV

ConcatBoundValue (new [] {imageDirectory BoundValue news

statusBinding});

Tell the bean image where to find the source attribute of the image

statusImageBean.setAttributeValue (SOURCE_ATTR, statusCBV);

For accessibility compliance, you specify the replacement text

for an image. Note that you must never use static text as shown

(always source translatable dictionary messages when

display text set values programmatically) and, ideally,.

the replacement text must in this case should clearly

the status of the image represents. Generally, we recommend that

you use a blender as described for the column remove easily

display different images, with a text alternative associated, but we

wanted to show how to use a bound value also in this workshop.

statusImageBean.setAttributeValue (SHORT_DESC_ATTR,

"Flag State employee");

And it's the exception error:
