Does this make any difference? VariantCart.PARENT_VARIANT.dot(VariantInventory.PARENT_VARIANT).dot(VariantOrdered.PARENT_VARIANT).dot(VariantAvailable.PARENT_VARIANT).eq(availableVariant);
The other thing I see is you are going up 4 here, not three as you did for availableVariant. Perhaps that should be: VariantCart.PARENT_VARIANT.dot(VariantInventory.PARENT_VARIANT).dot(VariantOrdered.PARENT_VARIANT).eq(availableVariant); ?
