include , exclude methods in formgroup class deprecated in rc5 , removed in rc6. so, how supposed build conditional validation? used call include/exclude form control name. addcontrol , removecontrol alternative? in rc6 (and future versions) i've solved issue using abstractcontrol enable , disable methods. example: // before (rc5): //this.formgroup.exclude('controlname'); // after (rc6): this.formgroup.get('controlname').disable(); // before (rc5): this.formgroup.include('controlname'); // after (rc6): this.formgroup.get('controlname').enable(); hope helps you.

i've noticed there several uses of pd.dataframe.groupby followed apply implicitly assuming groupby stable - is, if a , b instances of same group, , pre-grouping, a appeared before b , a appear pre b following grouping well. i think there several answers implicitly using this, but, concrete, here one using groupby + cumsum . is there promising behavior? documentation states: group series using mapper (dict or key function, apply given function group, return result series) or series of columns. also, pandas having indices, functionality theoretically achieved without guarantee (albeit in more cumbersome way). although docs don't state internally, uses stable sort when generating groups. see: https://github.com/pydata/pandas/blob/master/pandas/core/groupby.py#l291 https://github.com/pydata/pandas/blob/master/pandas/core/groupby.py#l4356 as mentioned in comments, important if consider transform return series it's index aligned origin
