I have written simple search app using Tapestry 5.0.15. User query from text
field is passed between requests via onPassivate and onActivate methods.
Here is a page class source excerpt:
public class Index
{
private String _userQuery;
private String _correctedQuery;
@ApplicationState
private NscopeDataSource _dataSource;
...
private String getByteString(String str)
{
if(str == null || str.isEmpty())
return "";
String result = "";
try
{
byte[] bytes = str.getBytes("utf-8");
for(Byte b: bytes)
result += Integer.toHexString(Math.abs(b.intValue())) + ", ";
}
catch (UnsupportedEncodingException ex) { }
return result;
}
void onActivate(String aUserQuery)
{
this._userQuery = aUserQuery;
if(_userQuery != null)
System.out.println("--- MEMBER USER QUERY ACTIVATE: " +
getByteString(_userQuery));
}
Object onPassivate()
{
if(_userQuery != null)
System.out.println("--- USER QUERY PASIVATE: " +
getByteString(_userQuery));
return (Object)_userQuery;
}
public String getUserQuery()
{
return _userQuery;
}
public void setUserQuery(String aUserQuery)
{
this._userQuery = aUserQuery;
}
...
The problem is that _userQuery with diacritic characters are messed up. It
looks like _userQuery is utf-encoded meny times. For query "miłość" (love in
polish) this code produces following output in server log:

When onPassivate method is called for the first time all characters are ok,
but in the subsequent onActivate it's not.
I don't know Tapestry very well yet, so my another question is why
onPassivate is called so many times?
BTW: if _userQuery is passed via persistent member (@Persist) everything is
ok. But it will not work for me.
This problem occured when I deployed app on linux server. On Windows
everything works fine.
Application source and output encoding is set to UTF-8.
thanks in advance for any help.
