Bugfix

Detail

#27402

setting the value of an ordered association may lead to NullPointerException

LiveList

The following command sequence results in a NullPointerException:

Setting the values of an association using a "live" tl:OrderedLinkQuery (See AbstractWrapper#setOrderedValue(TLObject, OrderedLinkQuery, List)).
Request the "live" list (See AbstractWrapper#resolveLinks(TLObject, AbstractAssociationQuery)).
Changing the values of this association as above.

=> A NullPointerException occurs.

Cause

When converting the values, the orders are set to the links one by one. When the order is set to the first link, the association cache tries to adjust the position of the link in the list due to the change. For this purpose, this link is searched with respect to the order comparator. This cannot handle the fact that an order (namely the order of all later links) is zero.

Solution

The method must not be called with "live" queries.

Test

No test.
