objective c - Does an ArrayController's Selection Persist Across Tabs? -

-

i have 2 arraycontrollers in interface builder bound 2 sets of core data entities. 2 entities have parent/child relationship. have nstableview bound parent entities' arraycontroller on first tab of nstabview. second tab of nstabview has nstableview bound child entities' arraycontroller. child arraycontroller's content set bound parent arraycontroller controller key: selection , model key path: <name of child relationship>

what i'm trying allow user select entity list of parents, switch tabs , work list of children.

what's happening if start app empty storedata file, can add parents, cannot add children. if add parents, restart app, can add children. list of children, however, doesn't seem filtered parent selected on first tab.

the way can explain behavior if arraycontroller's selection not persisting across tabs, case? there else i'm missing?

it's possible. i've never done myself, sounds need experiment , see. if nothing else setting nstabviewdelegate http://developer.apple.com/library/mac/#documentation/cocoa/conceptual/tabview/tasks/usingtabviewdelegate.html , asking controller selected object before , after tab view item selected.

i curious myself , looked through documentation myself, doesn't appear describe happens views when being selected.

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
