i doing research pattern scanner came problem. the pattern scanner saw needed handler of process way i'm doing process[] p = process.getprocessesbyname("pname"); doesn't have p.handle , went msdn there says have. why mine doesn't? what difference between 2 lines of code? process p = process.getprocessesbyname("pname")[0]; process[] p = process.getprocessesbyname("pname"); this gets first process has name of "pname": process p = process.getprocessesbyname("pname")[0]; note cause "index out of bounds" exception if there aren't any. this gets list (or array, actually) of processes have name of "pname": process[] p = process.getprocessesbyname("pname"); note won't cause exception if there aren't any; it'll return empty array. with latter, can index former, if want first match: process[] p = process.getprocessesbyname("pname"); if (p.len

i have use case have list of clients. client can added or removed list, , can have different start dates, , different initial parameters. i want use airflow backfill data each client based on initial start date + rerun if fails. thinking creating subdag each client. address problem? how can dynamically create subdags based on client_id? you can create dag objects dynamically: def make_client_dag(parent_dag, client): return dag( '%s.client_%s' % (parent_dag.dag_id, client.name), start_date = client.start_date ) you use method in subdagoperator main dag: for client in clients: subdagoperator( task_id='client_%s' % client.name, dag=main_dag, subdag = make_client_dag(main_dag, client) ) this create subdag specific each member of collection clients , , each run next invocation of main dag. i'm not sure if you'll backfill behavior want.

why did this: the reason use kind of approach because want workflow wait @ node until video gets copied, @ same time want notified % of progress made while copying sent different application @ every 2s. problem faced: at random while executing workflow intermediate message catch event on boundary not registered , error first callback video copy application when tries correlate message event on boundary. their others ways making simple loop in camunda achieve same behavior but random error in case concern if 1 knows same issue or if better approach can me. the approach non-interrupted boundary event valid, maybe bit verbose. prefer on loop construct, have thought "just" updating process variable outside indicate status? not need bpmn element allow this. see example rest api on update of process variables: https://docs.camunda.org/manual/7.7/reference/rest/process-instance/variables/put-variable/ . same of course possible java api. at random while

is other android devices having leanback feature except androidtv? i want restrict app on play store android tv. so, have added manifest <uses-feature android:name="android.software.leanback" android:required="true" /> from "https://developer.android.com/training/tv/start/start.html#declare leanback support" is right way restrict androidtv on play store? declare app uses leanback user interface required android tv. if developing app runs on mobile (phones, wearables, tablets, etc.) android tv, set required attribute value false. if set required attribute value true, app run on devices use leanback ui. the way interpret this, limits app tv.
