Hi totojack- I think you're right that the key property is useless now that you're using the positional index to access your list elements.
Also, the type conversion page says that using the unique id indexed approach won't allow for automatic creation of instances. The docs say the following: "Unlike Map and List element properties, if fooCollection(22) does not exist, it will not be created. If you would like it created, use the notation fooCollection.makeNew[index] where index is an integer 0, 1, and so on." I haven't been able to get makeNew to work and no one on the list responded to a previous question on it so I'm assuming that the feature is deprecated and the documentation is out of date. Which is really a shame since positional indexing of a list comes with some risks that accessing elements by unique id does not. You can write some hacks to get around this, but they lack the elegance that a web framework that really understood collections could have provided. totojack wrote: > > The problem of songs list size is solved using #stat.index.
