Temporary VO throws JBO-25058: Definition 0 of type Attribute is not found

Question

Hello,
I'm working with ADF 11.1.1.5.
I know that this error message usually indicates a misspelled attribute name.
But my code ist this:ViewObject tVO = _myApplicationModel.createViewObjectFromQueryStmt(null,
                            "select count(1) as my_count from table where other_attr = ?");
tVO.setWheresetWhereClauseParam(0, someValue);
tVO.execureQuery();
Object countReturned = tVO.first().getAttribute(0); // literal int 0 as indexThis code was working for several years. My SCM shows no differences to the last known working version.
But today it started throwing oracle.jbo.NoDefException: JBO-25058: Definition 0 of type Attribute is not found in ViewDefImpl_189_190.
     at oracle.jbo.server.ViewRowImpl.getAttribute(ViewRowImpl.java:866)
     at my.package.MyApplicationClass.methodUsingTempVo(MyApplicationClass.java:lastLineInExample)
...How can this code fail at all?
How do I solve this?
bye

I suppose you check this before:Object countReturned = tVO.first().getAttribute("my_count");
No. I did not expect this to work anyhow while accessing via index fails.
BTW:
Currently the error disapeaed.
The only thing I did was to relaunche the application. I did not change any code. Neither I recompiled.
I'm not a religious man but look's like I have sacrifice something to any good for this not happening in production. I'm thinking of an Oracle licence... ;o)
