Re: [xwiki-devs] [VOTE] Introduce BlockCollection Block wrapper

Hi devs, In many APIs we sometime want to manipulate several Block but we don't want to put them in a meaningful Block like XDOM which is supposed to mean a full document. Right now the only way to do it is to have both an API with Block and another with Collection<Block> but it's a bit more annoying for return type where you are forced to return a List<Block> even if you are in a case where you actually have only one Block to return like in macros for example. We talked a long time ago with Vincent about a BlockCollection which would not have any meaning (i.e. no corresponding event in the stream rendering API) and would just be here to be able to pass several blocks as a Block. Since UI extension is going to use it a lot I propose to introduce it now. WDYT ?

Any better idea for the name ?
