This is only required if you are preventing event\npropagation.\n\nI understand that the cellEditor params exist as the props being passed to the react version of the component but I can't seem to find how to attach to onKeyDown as specified in the docs. In my constructor for my cellEditor the onKeyDown function exists and matches the onKeyDown specified in cellEditorParams inside my column definition (if it exists).\nconstructor(props) {\n super(props);\n // console.log(typeof props.onKeyDown == 'function') => 'true'\n}\n\nBut it's never reached if it simply exists in the component\nonKeyDown(event) {\n console.log('not reached');\n}\n\nIt does get invoked if I put onKeyDown={this.props.onKeyDown} inside of a top level wrapping div around my input but it still doesn't catch the "Enter" press.\nI tried listening to the cell containing my custom cell editor\nthis.props.eGridCell.addEventListener('keyup', (event) => {\n console.log(event.keyCode === 13)\n})\n\nWhich does capture the enter press but it seems to unmount when enter is pressed before I can capture the final enter press inside the field?

[ "Member variables of a object get overridden when creating another object in the object", "I have a memory issue with a class of mine. The issue occurs when I create an object in a member function of a class. It is about the class below. I removed the member functions because they aren’t necessary: \n\nclass User\n{\nprivate:\n bool locked;\n bool active;\n\n std::vector<City> * userCitys;\n UserData userData;\n Credentials credentials;\n\n\nThe problem occurs when I call this function:\n\nint User::addCity(CityData cityData) \n{\n lockUserObject(); //Everything is fine here\n\n City cityToAdd; //When this object is created, the memory of userCitys will get overridden\n cityToAdd.activate();\n userCitys->push_back(cityToAdd);\n int cityID = userCitys->size() - 1;\n\n userCitys->at(cityID).editCityData(cityData);\n\n unlockUserObject();\n return cityID;\n}\n\n\nIn the first place I created userCitys on the stack. For test purpose I placed it on the Heap. The address of userCitys get overridden by some data. I can’t find the problem. the City is just a basic class:\n\nPart of the header:\n\nclass City\n{\nprivate:\n bool active;\n Supplies supplies;\n std::vector<Building> buildings;\n std::vector<Company> companies;\n std::vector<Share> shares;\n std::vector<Troop> troops;\n CityData cityData;\n\n\nConstructor:\n\nCity::City()\n{\n active = false; \n}\n\n\nHow is it possible that userCitys get overridden? This all happens on a single Thread so that can’t be a problem. I tried a lot of thing, but I can’t get it to work. What is the best approach to find the problem?\n\nEdit:\nLock function:\n\nvoid User::lockUserObject()\n{\n for( int i = 0; locked ; i++)\n {\n crossSleep(Settings::userLockSleepInterval);\n\n if( i >= Settings::userLockMaxTimes )\n Error::addError(\"User lock is over userLockMaxTimes\",2);\n }\n\n locked = true;\n}\n\n\nI call the code here (Test function):\n\nCity * addCity(User * user)\n{\n Location location;\n location.x = 0;\n location.y = 1;\n\n CityData citydata;\n citydata.location = location;\n citydata.villagers = 0;\n citydata.cityName = \"test city\";\n\n int cityID = user->addCity(citydata); //addCity is called here\n City * city = user->cityAction(cityID);;\n\n if( city == NULL)\n Error::addError(\"Could not create a city\",2);\n\n return city;\n}\n\n\nThe add user (Test code):\n\nUser * addUser()\n{\n UserData test;\n test.name = \"testtest\";\n Credentials testc(\"testtest\",3);\n\n //Create object user\n int userID = UserControle::addUser(test,testc);\n User * user = UserControle::UserAction(userID);\n\n if( user == NULL)\n Error::addError(\"Could not create a user\",2);\n\n return user;\n}\n\n\nMy test function:\n\nvoid testCode()\n{\n User * user = addUser();\n City * city = addCity(user);\n}\n\n\nThis function in called in main:\n\nint main()\n{\n testCode();\n return 0;\n}\n\n\nHere are UserAction and addUser in UserControle:\n\nint UserControle::addUser(UserData userdata, Credentials credentials)\n{\n int insertID = -1;\n for( int i = 0; i < (int)UserControle::users.size(); i++)\n {\n if( !UserControle::users.at(i).isActive() )\n {\n insertID = i;\n break;\n } \n }\n\n User userToInsert(userdata,credentials);\n\n if( insertID != -1 )\n {\n UserControle::users.insert( UserControle::users.begin() + insertID,userToInsert);\n return insertID;\n }\n else\n {\n UserControle::users.push_back(userToInsert);\n return UserControle::users.size() - 1;\n }\n}\n\nUser* UserControle::UserAction(int userID) //check all indexes if greater then 0!\n{\n if( (int)UserControle::users.size() <= userID )\n {\n Error::addError(\"UserAction is out of range\",3);\n return NULL;\n }\n\n if( !UserControle::users.at(userID).isActive())\n {\n Error::addError(\"UserAction, the user is not active.\",3);\n return NULL;\n }\n\n return &UserControle::users[userID];\n}" ]

I followed the tutorial at https://github.com/developmentseed/jekyll-ga.\nI followed all the following steps \nSet up a service account for the Google data API\n\n-Go to https://code.google.com/apis/console/b/0/ and create a new project.\n-Turn on the Analytics API and accept the terms of service\n-Go to API Access on the left sidebar menu, create a new oauth 2.0 client ID, give your project a name, and click next.\n-Select Application type: Service account, and click Create client ID\n-note the private key's password. It will probably be notasecret unless Google changes something. You'll need to enter this value in your configuration settings.\n-Download the private key. Save this file because you can only download it once. Copy it to the root of your Jekyll repository. Safety tip: To protect this file, add its file name to your .gitignore file and to the exclude list in your _config.yml file\n-Note the Email address for the Service account. You'll need this for your configuration settings and in the next step.\n\n\nSo I have the following page in my google page (https://console.developers.google.com/iam-admin/iam/project?project=inger-analytics)\n\n\nThe last step is the following : Log into Google Analytics and add the service account email address as a user of your Google Analytics profile: From a report page, Admin > select a profile > Users > New Userhttps://analytics.google.com/analytics/web/provision/?authuser=0#provision/SignUp/) I have the following page\n\nAnd the sign up button leads me to a form where I must enter information about the site that will use for my site.
