Customer Validator - List always empty

[Marc Huber]

Hi,

I have two Array-Lists. One Array-List (VersorgDataEntryListCompare) contains only data from database; the other (VersorgDataEntryList) is filled with data from database, too. The data of VersorgDataEntryList are shown by h:dataTable e.g.


If the user press the button "Speichern", the data from the inputfields are load into VersorgDataEntryList (the old values are deleted before)


The problem:

I want to proof, if the date from VERSORGUNG_VON is after the date of VERSORGUNG_BIS and if the inputvalues are not the same as in database.

For example:

Correct:
VERSORGUNG_VON.........VERSORGUNG_BIS
22.10.2000......................30.11.2004

Wrong
VERSORGUNG_VON........VERSORGUNG_BIS
12.10.2006.....................30.11.2004

Also wrong
VERSORGUNG_VON (database).....VERSORGUNG_VON (inputfield)
12.10.2006...................................12.10.2006


So i have written my own Validator.

I use the id-number of the component to know the number of fields and to know, from which field the value come from.

But my two list's are empty in this method. If I write a "normal" method (not a validator-method) to test, but there the list's are filled.
Why are both list's in the validator-method empty?

	public void dateValidate(FacesContext ctx, UIComponent comp,
		    Object value) throws ValidatorException {
		Date d = (Date)value;
		String[] sid = comp.getClientId().split(":");
		Integer id = Integer.valueOf(sid[1]);	

		
		if(versorgData.getVersorgDataEntryList().get(id).getVersorg_Von().
				equals(versorgDataCompare.getVersorgDataEntryListCompare().get(id).getVersorg_Von())
			&&
			versorgData.getVersorgDataEntryList().get(id).getVersorg_Bis().
			equals(versorgDataCompare.getVersorgDataEntryListCompare().get(id).getVersorg_Bis()))
			
			{
		      throw new ValidatorException(
		              new FacesMessage("Bitte Werte ändern; Werte sind unverändert", null));
			}
		else if (versorgData.getVersorgDataEntryList().get(id).getVersorg_Von().
				after(versorgData.getVersorgDataEntryList().get(id).getVersorg_Bis()))
		{
		      throw new ValidatorException(
		              new FacesMessage("Zeit Von ist nach Bis Zeit", null));
		}
		
	}

Or is there a better way to compare two fields?


Thank you
