Allow select headerKey to be resolved to non-string objects
-----------------------------------------------------------
Key: WW-2797
URL: https://issues.apache.org/struts/browse/WW-2797
Project: Struts 2
Issue Type: Improvement
Components: Plugin - Tags
Reporter: Scott Lewis
Currently, it seems that the headerKey value always resolves to a String.
However, sometimes the list that corresponds to the rest of the select may have
keys that resolve to other objects, such as Integer. Thus, when passing in
lists of "selected values", if you use this other object type, such as a
List<Integer>, the headerKey value cannot be "pre-selected", as the types will
not match; you'd have to use a more generic List to get it to work.
It would be nice if you could have headerKey match the type of the other keys
in the list, or at least be compatible with lists of a certain type.
