action “send to app” not working
-
Klaus794 years ago #19824
I do not get a channel from following code snippet.
var oChannel = getChannel(this, sChannelId);
if (!oChannel) {
// no channel
if (Log.isLoggable(Log.Level.DEBUG, “sap.ui.core.EventBus”)) {
Log.debug(“Failed to publish into channel ‘” + sChannelId + “‘.” + ” No such channel.”, sChannelId, “sap.ui.core.EventBus”);
}
return;
}Problem is following line: getChannel(this, sChannelId);
getChannel returns ‘undefined’.
sChannelId = Password_ModulToApp
which channel/data is missing?

sap.ui.getCore().getEventBus().publish(this.getModuleName() + “ToApp”, “statusMessage”, adataForstatusMessage);
the generated code “this.getModuleName() + “ToApp” creates in my oppinion the wrong channel name <modul_name>+”ToApp” (results in my example in: “Password_ModulToApp”
But if i change it to “Screen_StatusDialog” (channel will be found now) I get another error “no event is registered” (see Simplifier code below).
var aEventListeners will be ‘undefined’.
var aEventListeners = EventProvider.getEventList(oChannel)[sEventId];
if (Array.isArray(aEventListeners)) {
// this ensures no ‘concurrent modification exception’ occurs (e.g. an event listener deregisters itself).
aEventListeners = aEventListeners.slice();
var oInfo;
for (var i = 0, iL = aEventListeners.length; i < iL; i++) {
oInfo = aEventListeners[i];
this._callListener(oInfo.fFunction, oInfo.oListener || this, sChannelId, sEventId, oData);
}
} else if (Log.isLoggable(Log.Level.DEBUG, “sap.ui.core.EventBus”)) {
// no listeners
Log.debug(“Failed to publish Event ‘” + sEventId + “‘ in ‘” + sChannelId + “‘.” + ” No listeners found.”, sChannelId + “#” + sEventId, “sap.ui.core.EventBus”);
