ClassCastException error in Controller object

Question

HI folks,
I'm getting this ClassCastException error in the controller I'm extending. Basically, I'm trying to access the row values of a table which is created as OATableLayout and OARowLayout. My repeated attempts to solve this has failed. I wonder if one of you experts can figure this out. Here is the relevant runtime error message:
## Detail 0 ##
java.lang.ClassCastException: oracle.apps.fnd.framework.webui.beans.form.OAFormValueBean
     at oracle.cabo.ui.beans.layout.TableLayoutBean.getRowLayout(Unknown Source)
     at xbol.oracle.apps.hxc.selfservice.timecard.webui.XXTimecardCO.processFormRequest(XXTimecardCO.java:57)
The lines 56 & 57 is below:
OATableLayoutBean tableBean = (OATableLayoutBean)oawebbean.findChildRecursive("ConfigUIBean");
OARowLayoutBean rowBean = (OARowLayoutBean) tableBean.getRowLayout(0);
By the way, can I use TableLayoutBean instead of OATableLayoutBean, even though the original table was created as OATableLayout? The getRowLayout method is actually from TableLayoutBean.
Thanks

Let me try to start with the exception that you are getting.
The ClassCastException that you see in your first post is because the API call as below
OARowLayoutBean rowBean = (OARowLayoutBean) tableBean.getRowLayout(0);returns a FormValueBean and not a RowLayoutBean. This is the reason that you were getting this error.
I believe that the findChildRecursive(..) API exists in the Table Layout Bean. Please, check the javadoc
<JDEV_CLIENT_INSTALL_DIR>/jdevdoc/javadoc/fwk/oracle/apps/fnd/framework/webui/beans/layout/OATableLayoutBean.html#findChildRecursive(java.lang.String)
Can you please explain if you are still getting any errors even after the below code
OATableLayoutBean tableBean = (OATableLayoutBean)oawebbean.findChildRecursive("ConfigUIBean");
OARowLayoutBean rowBean = (OARowLayoutBean)tableBean.getIndexedChild(0);
