php - OXID eShop: save() in an foreach does not work / don't understand save() function -

i want create copies of articles new oxid , new oxartnum. if call function create 1 new article works.

like that:

$this->copyarticle('my_oxid'); 

but call addarticle function in foreach loop. exception, saying there duplicate primary value (oxid primary field).

exception thrown

foreach($this->getatmp() $soxid => $iexcess){     $this->copyarticle($soxid); } 

the oxid generated correctly, there no duplicate. think problem oxids save function. article oxids copy selected in form. arrays contain correct values.

the problem $oarticle->save() function.

for understanding is:

1. load article
2. modify fields
3. save article

my code:

edit: works, not , the duplicate primary exception thrown.
