good afternoon, everyone! i'm trying figure out how map objects nested arrays, project keeps being terminated due uncaught exception. assume i'm not mapping correctly, i'm being told isn't key-value coding compliant. how map object nested array? following footprint of json i'm trying map, interface , implementation, , error that's being throw, respectively. finally, there link project on github, incase i've left out, or seeing full source helpful. json { "href": "string", "items": [ { "type": "string", "status": "string", "name": "string", "publisher": "string", "publisherid": "string", "description": "string", "url": "string", "smalllogoimageurl": "string", "tileimageurl": "string...

i using github windows on windows 7. have bash script add ssh-key ssh-agent. have setup ssh remote repo. add_key.sh #!/bin/bash cd ../ssh/ eval $(ssh-agent) ssh-add id.rsa cd ../htdocs/ execute command- ./add_key.sh it returns agent pid 5548 identity added: id.rsa (id.rsa) when git push origin master, fails. when manually cd in ssh directory, , run same ssh-related commands , cd directory htdocs , git push origin master, works. why happening? your problem script running in own shell session because running ./add_key.sh . this means variables set eval $(ssh-agent) not living beyond shell session parent session doesn't have them , cannot use agent (also might spawning new agent each time run script). the fix run "script" in current session dot-sourcing script instead of running external script. that want use . add_key.sh .
