[infinispan-issues] [JBoss JIRA] (HRJS-3) Iterator doesn't work properly on cluster

Iterator doesn't work properly on cluster ----------------------------------------- Key: HRJS-3 URL: https://issues.jboss.org/browse/HRJS-3 Project: Infinispan Javascript client Issue Type: Bug Affects Versions: 0.2.0 Reporter: Galder Zamarreño Assignee: Galder Zamarreño Fix For: 0.3.0 While porting the tests for local mode also to cluster mode, I have faced the following issue: When calling iterator on client connected to one of the nodes of 3 node cluster, the result of iteration is not correct. You can find the test [here|https://github.com/andyuk1986/js-client/blob/ISPN-6381/spec/infinisp...]. The test run returns the following result: {code} 1) Infinispan cluster client can iterate over entries using different clients Message: Expected { done : true, key : 'it2', value : 'v2' } to equal <jasmine.objectContaining({ key : 'it1', value : 'v1', done : false })>. Stacktrace: Error: Expected { done : true, key : 'it2', value : 'v2' } to equal <jasmine.objectContaining({ key : 'it1', value : 'v1', done : false })>. at /home/amanukya/Documents/Red Hat Workspace/js-client/spec/utils/testing.js:208:43 at /home/amanukya/Documents/Red Hat Workspace/js-client/spec/utils/testing.js:413:39 at Function._.map._.collect (/home/amanukya/Documents/Red Hat Workspace/js-client/node_modules/underscore/underscore.js:172:24) at /home/amanukya/Documents/Red Hat Workspace/js-client/spec/utils/testing.js:409:7 at /home/amanukya/Documents/Red Hat Workspace/js-client/spec/utils/testing.js:362:43 at tryCallOne (/home/amanukya/Documents/Red Hat Workspace/js-client/node_modules/promise/lib/core.js:37:12) at /home/amanukya/Documents/Red Hat Workspace/js-client/node_modules/promise/lib/core.js:123:15 at flush (/home/amanukya/Documents/Red Hat Workspace/js-client/node_modules/promise/node_modules/asap/raw.js:50:29) 2) Infinispan cluster client can iterate over entries using different clients Message: Expected { done : true } to equal <jasmine.objectContaining({ key : 'it2', value : 'v2', done : false })>.
