smack - Issue with obtaining the offline messages using openfire server -


offline messages not delivering user when person avails.

delayinformation info = (delayinformation)message.getextension("x","jabber:x:delay");

returns null.

when iterate collection of message.getextensions() , delay urn:xmpp:delay.

can explain on this. i'm using smack , smackx.jar. though smackx.jar has smack.providers it's not taken account.

some suggested use urn:xmpp:delay ,which results in class cast exception.

delayinformation inf = (delayinformation)message.getextension("delay","urn:xmpp:delay");

exception: java.lang.classcastexception: org.jivesoftware.smack.packet.defaultpacketextension

if android using smack library try this:

extensionelement delay = message.getextension("urn:xmpp:delay"); if(message.getextension("urn:xmpp:delay") != null){      log.i("recveived", "delay 1: " + delay.toxml());     log.i("recveived", "delay 2: " + delay.getnamespace());     log.i("recveived", "delay 3: " + delay.getelementname()); }


log output:

i/recveived: delay 1: <delay xmlns='urn:xmpp:delay' stamp='2017-07-31t04:09:23.224+00:00' from='81.89.100.197'></delay>  i/recveived: delay 2: urn:xmpp:delay  i/recveived: delay 3: delay

this possibillity:

delayinformation delayinformation = delayinformation.from(message); if (delayinformation != null) {      log.i("recveived", "delay 1 : " + delayinformation.getstamp());     log.i("recveived", "delay 2 : " + delayinformation.getstamp().gettime()); }

log output: 

i/recveived: delay 1: mon jul 31 06:08:58 gmt+02:00 2017 i/recveived: delay 2: 1501474138319

good luck

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
