Hi,
Please see this lines:
<s:property value='#parameters.eventoId'/><br/>
<s:property value='%{"hello" + #parameters.eventoId}'/><br/>
<s:property value='%{"hello" + #parameters.eventoId[0]}'/>
Let's say that parameter eventoId == 9, it outputs:
9
hello[Ljava.lang.String;@144c5bb
hello9
The funny thing is that #parameters.eventoId' is evaluated to String
when it's alone (what I expected to be), but it is evaluated to an
String array when concatenated like in "hello" + #parameters.eventoId.
As expected, taking the first array element ([0]) solves the problem.
But the question is if this is OK to be this way, am I building the
OGNL expression wrongly, or is it some bug in the OGNL evaluation
code?
