OAF, used with the clausule setWhereClause display object, show the error not correctly initialized.

Hi all,

I'm new with ofa and AM mi to VO that I use to find the information that is displayed to the user on a region of the query, after the user has pressed the button go demand CO AM tho load VO both use this information to display in a popup region to display and update. the main problem is the closing of popup region it send a shipment to the server one appears the error "View object may not be correctly initialized during update."

The main page and the pop-up window uses the same AM, the initM2mVo() and initTavleVo() are called by processRequest of the main PG CO, the popup dosen´t have a CO.

This AM using PG main and in the region of popup

Thank you all.

I thing I got the problem.

I have the following configuration:

A Home Page and external RN which is call as popup in the homepage
2 VO, java code queries, one to capture information that is used to query the VO 2 that I use to update the information in the pop-up window.
01:00, this is the card only in the main Page. (Initially, I had mapped to AM even external RN as the main PG, but I take it off).

The solution was to remove the mapping of the AOS of the outer region and in the messageimput of the whole of the outer region of the instance of the view and the view attribute manually in this field (http://screencast.com/t/uDTALEedCh do not use the Wizard) that one instantiation am AM, so the problem, it seems that was that defining an AM in the outer region create a new instance , causing that he cannot see the information I manually load in the t by request it them.

in this case there is no need to use the following code, because the lines are responsibility of the query information in the java code, it must only be made when inserting a new line.

    public void initM2mVo(){
        //get a handle to the View Object that we wish to initialize
        OAViewObject vo = (OAViewObject)this.getTascTransEqInstM2mVO1();
        if (!vo.isPreparedForExecution()) {
            vo.setMaxFetchSize(0);
            vo.executeQuery();
        }
        //Create a blank Row
        Row row = vo.createRow();
        //Attach that blank row to the VO. Data will be fed into this row, when the user types into the fields
        vo.insertRow(row);
        //Set the status of the blank row to initialized. This tells OA Framework that record is blank and must not be included in DML
        //Operations until    changes are made to its underlying VO [via screen fields]
        row.setNewRowState(Row.STATUS_INITIALIZED);
    }
