Difference between version 10 and version 4:

At line 25 changed 1 line.
Now, struts will not set a Date object on your form (even if you apply the datePatten dd/MM/yyyy).
Now, struts will not set a Date object directly from your form (even if you apply the datePatten dd/MM/yyyy).
At line 27 changed 1 line.
So you need a field to capture the string input:
So you need a field to capture the string input of the dob field, so now your Form looks like this:
At line 30 changed 1 line.
private String dobString;
public MyForm {
java.util.Date dob;
String dobString;
}
At line 33 changed 1 line.
Struts only seems to be able to set the date property as a java.lang.String... you will of course need getters and setters on these as well.
You will of course need getters and setters on these as well.
At line 54 changed 1 line.
return this.datetimeOfOffence;
return this.dob;
At line 67 changed 6 lines.
if (getDob() != null) {
StringBuffer date = new StringBuffer();
dateTime.append(getDobString());
return dateTime.toString();
}
return null;
return this.dobString;
At line 75 changed 1 line.
}}}
public void setDobString(String dobString) {
this.dobString = dobString;
}
At line 77 removed 3 lines.
Now, when you convert the form back to a POJO, the DateConverter (utils), will
convert the string back to a Date object (you need to check the DateConverter is applying the
correct datePattern in the SimpleDateFormat to map to your datePattern)
At line 81 changed 2 lines.
Q) What happens if you have 2 dates in your form, and they have different datePatterns?
A) I guess you would have to dynamically assign the correct converter (unregister DateConverter?)

At line 80 added 2 lines.
Now, when you convert the form back to a POJO, the Converters will call getDob() which will convert the dob string into a Date and return that (so it is working in the same way that getAddressForm() getAddress() works inside the UserForm... doing a type conversion... (you need to check the DateConverter is applying the correct datePattern in the SimpleDateFormat to map to your datePattern)
At line 86 added 32 lines.
Here are the DateConverter methods:
{{{
private static SimpleDateFormat standardDateFormat = new SimpleDateFormat(
"dd/MM/yyyy");
public static Date convertDateStringToDate(String dateStr) {
try {
return standardDateFormat.parse(dateStr);
} catch (ParseException pe) {
return null;
}
}
public static String convertDateToDateString(Date date) {
return standardDateFormat.format(date);
}
}}}
Finally, you should validate your date string input, so in your struts validation.xml file you should
have an entry that looks like:
{{{
<form name="myForm">
<field property="dobString" depends="required,date" >
<arg0 key='dob.message.key'/>
<var><var-name>datePattern</var-name><var-value>dd/MM/yyyy</var-value></var>
</field>
</form>
}}}
