If you are using the Intake service, then you must use the intake tool
within your action class for validation. It doesn't happen automatically
per se.
1. login
2. page request made
3. intake tool used in .vm to populate field names and default values if
any, if an exception is thrown in the action class, the intake tool
can store user's submitted results so they don't have to retype them
when making corrections
4. action class called from form submit
5. action class method asks intake tool for validation of your group
-> you handle where to send the user after this.
action class code to use intake tool:
------------------------------------------------------------------------
public void doInsert(RunData data, Context context) throws Exception
{
// Test for valid intake data
IntakeTool intake = (IntakeTool) context.get("intake");
if ( !intake.isAllValid() ) {
log.info("Intake has found an error with user data");
return;
} else
{
try
{
// get the "Note" Group
Note note = new Note();
Group group = intake.get("Note", IntakeTool.DEFAULT_KEY);
group.setProperties (note);
// now note is properly populated with the form data
// save the entry
note.setNew( true );
note.save();
/*
* now we must clear the intake group or the data
* will again repopulate the next call to this form
* which we don't want in this case
*/
intake.remove( group );
}
catch ( Exception e ) {
log.error("data exception for inserting a new note occured: " +
e.toString() );
data.setMessage("An error has occured when attempting to insert a new
note: " +
e.toString() );
}
}
}
