क्या विशेष रूप से अजीब है, एक और मीटर विभाग में एक और संबंध है कि वहाँ,: जब भी मैं एक विभाग की newsItems से अधिक की गणना करने में, इस प्रकार डाटाबेस से पुनः प्राप्ति के ट्रिगर की कोशिश, मैं इस त्रुटि मिलती है n इकाई, यह सिर्फ काम करता है, और मैपिंग कैसे स्थापित किया जाता है, इसमें कोई फर्क नहीं पड़ता है, मैंने कम से कम 10 बार चेक किया है।
