Problem with Calendar if the field is null

[aleajax]

After the major problem with this component was resolved (thanks) now i see another big problem.
If the field date of calendar is null i obtain these errors:

I put everthing but probably are sufficient only the first 3 lines.

When does this error happen exactly?

[aleajax]

Everytime there is nothing on the field date.
I use postgresql as database.

The check that i put on my JSF:
<h:outputLabel id="data_scadenza1" value="#{libriController.selected.data_scadenza==null}"/>
as output said:
true

However,after see the error code on:
return tokens[0].trim() + "/" + tokens[2].trim();
i make same experiments.

public class CalendarRenderer extends CoreRenderer {
String getPageDate(String date, Calendar calendar) {
...

Before:

String[] tokens = selectedDate.split("/");
return tokens[0].trim() + "/" + tokens[2].trim();

After this change on the code:

if (!date.trim().equals("")) {
String[] tokens = selectedDate.split("/");
return tokens[0].trim() + "/" + tokens[2].trim();
} else
return null;

the problem seem gone away.

I think was a bug, if you could give a look at my solutions even using different database ...

For example i return null but i don't known if is most appropriate return something other things.

This was a quickly change because i want use this component ...

It seems like a bug yes, can you please create a ticket in our issue tracker with your description or just a link to this post so we can quickly fix this and make it available for a nightly snapshot build.

[aleajax]

I put the ticket 574

[cagatay.civici]

Great, thanks for your effort.

This will be fixed this week after replication of the issue.

[cagatay.civici]

Can you please try with latest snapshot as I can't replicate the issue now after enhancements to calendar.
