FacesCtrlListBinding getInputValue ADFv: error while reactivating a reg

Question

Jdev. 11.1.1.4
Trying to apply this in my application:
http://one-size-doesnt-fit-all.blogspot.com.es/2011/06/jdev-111140-afshowdetailitems-and_20.html
I'm getting this error while trying to programmatically reactivate my region after having deactivate it.
This is a piece of degub listing of one execution of my application:
<JUCtrlValueBinding> <startEvents> [8534] NumeroCopias: IGNORING Start events as it is not in active/push mode
<ADFLogger> <begin> Get LOV list
<JUMetaObjectManager> <getControlDefinitionFactory> [8535] JUMOM - CTRL_DEF_FACTORY not found: [ACTIVE] ExecuteThread: '1' for queue: 'weblogic.kernel.Default (self-tuning)'

<DCIteratorBinding> <refresh> [8540] Executing and syncing on IteratorBinding.refresh from :SvSolicitudesServicioAtrView2Iterator
Error translated to english:
*<FacesCtrlListBinding> <getInputValue> ADFv: Selected element of value 3 has not been found with type: oracle.jbo.domain.Number in the LOV.*
The first time I display the region this error doesn't happen. Then it is deactivated (finalizing the task flow) and when activating again (initializing the task flow again) the error appears just when displaying the first jsf page. The error is due to a soc field in the page. If I remove it, then it doesn't give any error.

Frank,
I have already found the problem.
You are right. What I am really doing is conditionally activating the region (with properties "activation" and "active"). I think this is ok.
The problem that I have found is due to that page had the iterator defined as ChangeEventPolicy=ppr. Previously to executing the page, in the task flow I do a CreateInsert operation on that iterator. The first time I acceess the page it executes ok and handles the new record as the current record. When deactivating and reactivating (or as you prefer to call it) the region, afeter executing the ceratInsert, when the page is executed the ChangeEventPolicy=ppr erexecuets de iterator and the "new" row (that was not posted nor committed to the database) is lost.
I have removed the ppr and now it seems to work better.
Is this the behaviour of the iterator PPR ?
