Unable to create Table Bean advanced search criteria

Question

Hi,
I want to create new search criteria for advanced search region. The reason being new search criteria i tried to add by personalization it didnt worked may be guessing construction mode is autocustomization mode. Somewhere i have seen if resultsbased it will work. Can someone confirm on this??
I'm trying to create new bean for search criteria at the specified location under <oa:table akRegionCode="EAM_AD_ASSET_RESULTS_TABLE" but unable to do so:
Here is the part of the page

I tried several ways :
OAPageLayoutBean pageLayout = oapagecontext.getPageLayoutBean();
OAQueryBean query=(OAQueryBean)pageLayout.findChildRecursive("EamAssetQueryRegion");
OATableBean oawebbeantb = (OATableBean)query.findChildRecursive("EAM_AD_ASSET_RESULTS_TABLE");
OAMessageLovInputBean ccidbean = (OAMessageLovInputBean)oapagecontext.getWebBeanFactory().createWebBean(oapagecontext, OAWebBeanConstants.LOV_TEXT, null, "xxValidation");
if (oawebbeantb==null){                    
throw new OAException("Error this is a test!", OAException.ERROR);
oawebbeantb.addIndexedChild(ccidbean); --here it getting null
OR
OATableBean oawebbeantb = (OATableBean)oawebbean.findIndexedChildRecursive("EAM_AD_ASSET_RESULTS_TABLE");
OAMessageLovInputBean ccidbean = (OAMessageLovInputBean)oapagecontext.getWebBeanFactory().createWebBean(oapagecontext, OAWebBeanConstants.LOV_TEXT, null, "xxValidation");
oawebbeantb.addIndexedChild(ccidbean); --here it getting null
Please someone help me on this..
thanks,

Answer 1

1) Search panel textinput item should be search allowed true and prompt is need. no other property need to set.
HERE YOU DONT WANT TO SET VIEW INSTANCE AND ATTRIBUTE SINCE WE ARE DOING FOR EXTENDED VO ITEM AS SEARCH ITEM.THAT'S OK. I TRIED WITH YOUR COMMENTS FOR TEXTINPUT ITEM TOO.
Comment--
textinput item created is a simple item without any VO instance , etc.
There is no question of extended VO item, its a simple textinput item.
value in this field is going to compare with the values in result table.
2) Search mapping, only search item id and result item id need to set.
I'M DOING HERE MAPPING FOR ABOVE SEARCH ITEM ID AND RESULT ITEM ID
Comment-- Perfect !!
3) Item created in table , after you extended Vo, view instance and attribute needs to set.
WHERE DO YOU WANT THIS TO BE SET?? CAN YOU ELABORATE THIS MORE PLEASE.MAY BE I'M MISSING HERE SOMETHING.
Comment-- you must have created message styled text item in adv table bean, assign VO instance and attribute to it, right?
4) One more thing Parag, do i need to include where clause for extended VO item in view object??
for ex:
where attribute(this is extended vo item)=:4
Comment-- No need. this will be handled by point#2 above, i.e. criteria and result items.
