Responsa for Shabbat 183:3

דאיתמר המוציא פירות לרה"ר אביי אמר ביד חייב בכלי פטור ורבא אמר ביד פטור בכלי חייב

And Raba said likewise: They learnt this only of a basket full of cucumbers and gourds, but if it is full of mustard he is culpable. This proves that he holds that the tie of a vessel is not regarded as a tie. Abaye ruled: Even if it is full of mustard he is not culpable, [which] proves that he holds that the tie of a vessel is regarded as a tie. Abaye [subsequently] adopted Raba's view, while Raba adopted Abaye's view. Now Abaye is self-contradictory, and Raba likewise. For it was taught: If one carries out produce into the street, — Abaye said: If in his hand, he is culpable;<span class="x" onmousemove="('comment',' Even if his body is in the house, because the tie of his body is not a tie in this respect. ');">⁷</span> if in a vessel, he is not culpable.<span class="x" onmousemove="('comment',' If part of the utensil is within, as R. Johanan supra 91b; this contradicts Abaye's subsequent view. ');">⁸</span> But Raba ruled: If in his hand, he is not culpable;<span class="x" onmousemove="('comment',' The tie of the body is a tie. ');">⁹</span>
