SpEL and collections

[bkeyser]

For a class Foo that contains a list of Bar objects

class Foo
{
List<Bar> bars;
}

class Bar
{
String str;
}

and for an SpEL expression of bars[0].str and attempting to set the string value, I am getting an UnsupportedOperationException because SpEL is setting the collection to an emptyList (I assume through Collections.emptyList).

I have set the autoGrowCollections to true.

How would one create a Bar object through SpEL that will allow it to set the value of a property?

Thanks,
Brian

I looked at the source code and didn't find anything that would assign an empty list. I took a look at my source code and I was too cute. I initialized the value to an emptyList for another purpose.

In short, no problems here.
