how vendor list objects using suitetalk java api. tried 1 vendor object string internalid = _console.readln(); // invoke get() operation retrieve record recordref recordref = new recordref(); recordref.setinternalid(internalid); recordref.settype(recordtype.vendor); readresponse response = _port.get(recordref); vendor vendor = (vendor) response.getrecord(); but if don't know internalids, there way vendors i don't know java api well, think you'll need create search returns vendors. you'll have list can process , extract internal ids from.

how can automatically provision new machines when docker swarm detects there not enough resources schedule services? i use setup rancher , docker swarm scheduler, , if there not enough resources, service creation fails: exit status 1: creating stresstest2_workerb1_1 creating stresstest2_workerb2_1 no resources available schedule container i can poll status , call docker machine when needed, rancher not attempt re-schedule missing services. wonder if there more integrated solution, maybe hook within docker swarm can used dynamically call docker-machine create or remove machines. i'm deciding between rancher docker 1.11 + docker swarm or docker 1.12 in swarm mode, solution fine. are using new docker swarm mode came in 1.12? there isn't hook in docker swarm this. swarm mode, use docker remote api collect events trigger instead of polling.

i'm trying wrap mind arround angular components, understand components better i'm developing simple todo crud using component architecture. the problem think makes sense put operations of crud in single controller respecting single responsibility principle @ same time practice (i think) split views (one list todos , delete create/update todos). i know multiple views single controller can achieved using 2 separate components registering same controller , ng/ui-route magic, using blows encapsulation proposal components try offer. so, has figured out solution problem? i think have consider modularity, can use create service handle crud , api operations , can reused other controllers , directives. here example of how did in our project. git repo of on of partners. https://github.com/leog/epsilon
