-----------------------------
Summary: Repopulating Field upon conversion Error does not work
when doing localization
Key: WW-3833
URL: https://issues.apache.org/jira/browse/WW-3833
Project: Struts 2
Issue Type: Bug
Affects Versions: 2.3.4, 2.3.3
Reporter: J. Garcia
Fix For: 2.3.5
In the documentation, there is a way to repopulate a field with the original
user input when there is a conversion error:
http://struts.apache.org/2.3.3/docs/conversion-validator.html
However, this does not work if you try to apply l10n to user input: integers,
dates, real numbers.
Current workaround:
In jsp:
<s:textfield key="user.born"
value="%{getFormatted('format.number','user.born')}" />
In BaseAction:
public String getFormatted(String key, String expr) {
Map<String, Object> conversionErrors =
ActionContext.getContext().getConversionErrors();
if (conversionErrors.containsKey(expr)) {
String[] vals = (String[]) conversionErrors.get(expr);
return vals[0];
} else {
final ValueStack valueStack =
ActionContext.getContext().getValueStack();
final Object val = valueStack.findValue(expr);
List<Object> valList = new ArrayList<Object>();
valList.add(val);
return getText(key, valList);
}
}
