Dynamically load header message in column

In backing bean I have List vrsteAktivnosti and based on kratica property in my object I want to build header so it can easily be internationalized. Plus add sufix '_kratica' to property.
If for example kratica resolves to KR in my resource bundle I have key KR_kratica.

<ui:param name="kratica_3" value="#{aktivnostBean.vrsteAktivnosti.get(3).kratica}_kratica" />
<p:column headerText="#{msg[kratica_3]}">
...

Some expression language basics:

• msg.someKey will look at message bundle for someKey
• msg['someKey'] will look at message bundle for someKey
• msg[someKey] will look at params to resolve property someKey
• msg[aktivnostBean.vrsteAktivnosti.get(3).kratica] will look at objects property kratica and then look at msg bundle
• msg[aktivnostBean.vrsteAktivnosti.get(3).kratica_kratica] will look at objects property kratica_kratica which does not exist, so use ui:param
