#{backingBean.someproperty[linkBean.arg1]} basically means:
BackingBean bean = (BackingBean)elExpr.getValue();
Object someProperty = bean.getSomeproperty();
LinkBean linkBean = (LinkBean)elExpr.getValue();
Object someArg = linkBean.getArg1();
return someProperty.get(someArg);
So I have no idea why you are trying to do "String[Integer]". EL
doesn't support returning characters in a string by index. What are
you trying to do?
Best thing is to give us a little of your JSPX code and then tell us
what you want. EL is no different than Java except the syntax is
different, it isn't magic. So figure out what you want to call, then
strip out the beginning get from properties and use [] to get items
from a Map by key or items in a list by index.
