I have ported my app from 1.4.18 to 1.5.1 (I haven't used 1.5.3 yet).
As part of my porting, I had to adjust the use of page parameters. I would
like to mention my changes for parameter extraction and existence
determination below, in case someone can mention a cleaner way to do these
things...
import org.apache.wicket.util.string.StringValue;
Replace
if (params.containsKey([Param name]))
{
String sValue = params.getString([Param name]);
...
}
with
List<StringValue> liSVs = params.getValues([Param name]);
if ((liSVs != null) && !liSVs.isEmpty())
{
StringValue svValue = liSVs.get(0);
String sValue = svValue.toOptionalString();
...
}
and replace
String sUserName = params.getString([Key name], [Empty default string]);
if (!sUserName.isEmpty())
...
with
List<StringValue> liSVs = params.getValues([Param name]);
if ((liSVs != null) && !liSVs.isEmpty())
...
