Description
In cases where a model includes an array of some smaller objects, the ChangeApplier offers no convenient way to add several more of these smaller objects to that array all in one go. For example, if the form of the model includes
{
things: [
{ thung: "foo" },
{ thung: "bar" }
]
}
If I wish to add three more 'thung's to 'things', I must fire three separate requests for a change, using the fully qualified EL path into 'things' i.e. using knowledge of how many 'thung's there already are:
applier.requestChange("things.2", newThungA);
applier.requestChange("things.3", newThungB);
applier.requestChange("things.4", newThungC);
It would be nice to be able to do it all in one request, so that only one modelChanged event is fired.
