I am using jQuery UI version 1.10.1, which definitely has the nested sortable fix added in 1.8.24.
However, the logic determining hasNestedSortableFix evaluates to -1, which later evaluates to false (used as !hasNestedSortableFix), since !-1 is false.
hasNestedSortableFix = version && version.indexOf("1.6.") && version.indexOf("1.7.") && (version.indexOf("1.8.") || version === "1.8.24");
As a result, I am encountering some pretty funky behavior (extra elements being added to the dom, other elements being cloned and replaced and removed after an unrelated action), and my observable data model not being updated. Setting the hasNestedSortableFix to false fixes this, since later this is negated to true.
I would request a fix in the version checking logic to allow for higher versions of jQuery UI which have the fix.
