BlankOption value in Select component should be configurable
------------------------------------------------------------
Key: TAPESTRY-2278
URL: https://issues.apache.org/jira/browse/TAPESTRY-2278
Project: Tapestry
Issue Type: Improvement
Components: tapestry-core
Affects Versions: 5.0.11
Reporter: Sven Homburg
Fix For: 5.0.12
i often use the option value of a select component holding id's for database
entities.
the id's type are most numeric values, so my problem is:
i attached an ajax request that sends each change from the select component.
the following method catch the event
@OnEvent(component = "inputProject", value = "change")
JSONValue projectIdChanged(long projectId)
{
.....
return mapper.toJSON(resultList);
}
if the user select the blank option
the component throws a NumberFormatException
so it were cool, if i declare the empty option value by my self.
