Hi,
we are trying to get OData work offline. It works fine online, but we get exception on oDataStore.Open. It stops with "Unknown network error occured" or in Windows "Exception calling native with command :: OData :: openOfflineStore ::exception=TypeError: Die Eigenschaft "OfflineStore" eines undefinierten oder Nullverweises kann nicht abgerufen werden." But there is no error for createOfflineStore.
Sample code:
var data = {
languageID: getLanguageId(),
hostName: "localhost", // host
port: 8090, // port
odataOnline: "/odata", // serviceRoot online requests
odataOffline: "/odata_offline", // serviceRoot offline requests
odataOfflineRequests: { // offline requests: definingRequests
"LGNTINITAnrede_ODataVIEW" : "/LGNTINITAnrede_ODataVIEW"
}
};
var getODataStore = function (complete, error) {
Log.call(Log.l.trace, "appSettings.");
var deferred = $q.defer();
if (oDataStore) {
Log.print(Log.l.trace, "oDataStore already opened");
complete(oDataStore);
deferred.resolve();
} else if (sap && sap.OData &&
typeof sap.OData.createOfflineStore === "function") {
window.setTimeout(function () {
Log.call(Log.l.trace, "appSettings.getODataStore.setTimeout");
var properties = {
name: "LeadSuccess",
host: data.hostName,
port: data.port,
serviceRoot: data.odataOffline,
definingRequests: data.odataOfflineRequests
}
oDataStore = sap.OData.createOfflineStore(properties);
if (oDataStore &&
typeof oDataStore.open === "function") {
Log.print(Log.l.trace, "createOfflineStore success! calling oDataStore.open()");
oDataStore.open(function () {
Log.call(Log.l.trace, "appSettings.oDataStore.open", "success!");
Log.print(Log.l.trace, "applyHttpClient() calling...");
sap.OData.applyHttpClient();
Log.print(Log.l.trace, "applyHttpClient() returned");
complete(oDataStore);
deferred.resolve();
Log.ret(Log.l.trace);
}, function (e) {
Log.call(Log.l.error, "appSettings.oDataStore.open", "oDataStore.open() failed!");
if (typeof e === "string") {
error({ status: 500, statusText: "open offline store failed with error:\r\n" + e });
} else {
error(e);
}
deferred.reject();
Log.ret(Log.l.error);
});
} else {
Log.print(Log.l.error, "createOfflineStore() failed!");
error({ status: 500, statusText: "Creating offline store failed" });
deferred.reject();
}
Log.ret(Log.l.trace);
});
} else {
Log.print(Log.l.error, "sap.OData missing!");
error({ status: 501, statusText: "OData offline store functionality not implemented" });
deferred.reject();
}
Log.ret(Log.l.trace);
return deferred.promise;
};
thanks for help or suggestions
