Harry Ring created MYFACES-4240:
-----------------------------------
Summary: <f:websocket /> onopen eventhandler is called only the
first time
Key: MYFACES-4240
URL: https://issues.apache.org/jira/browse/MYFACES-4240
Project: MyFaces Core
Issue Type: Bug
Components: JSR-372
Affects Versions: 2.3.1
Environment: java 1.8, tomcat 9.0.8, Windows 10
Reporter: Harry Ring
I use the socket below.
_<f:websocket id="usersocket" connected="false"_
_onmessage="userSocketListener"_
_onopen="userSocketOpened"_
_onclose="userSocketClosed"_
_onerror="alert('ERROR')"_
_/>_
If I call _jsf.push.open('usersocket')_ and __ _userSocketOpened()_ is called.
Then I call __ _jsf.__push.close('usersocket')_ and __ _userSocketClosed()_
is called.
Then I call __ _jsf.push.open('usersocket')_ and __ _userSocketOpened()_ is
not called.
I looked into
myfaces-api-2.3.1-sources.jar!\META-INF\internal-resources\org.apache.myfaces.core.api\jsf.js
and found the _onopen_ eventhandler in line 283:
_socket.onopen = function(event) {_
_{color:#d04437}if (reconnectAttempts == null) {color}{_
_var clientIds = clientIdsByTokens[channelToken];_
_for (var i = clientIds.length - 1; i >= 0; i--){_
_var socketClientId = clientIds[i];_
_components[socketClientId]['onopen'](channel);_
_}_
_}_
_reconnectAttempts = 0;_
_}_
When the socket is opened the first time reconnectAttempts is null, when the
socket is opened the second time reconnectAttempts is 0, so the line should be
_if (reconnectAttempts == null || reconnectAttempts == 0)_
