-- SORRY THERE SOMES ERRORS - 

Hi,

I have a little problem on my apps. When I want to search something, I do selection of parameters by WOPupUpButton.
But the problem is when I do the 1st search (1st fetch) there are no problem but when I want to do another search and I select another parameter in the WOPopUpButton which refresh the second one, the display page refresh all datas (do the fetch(1st search) I done before) and then update parameter of second WOPopUpButton. It makes my apps slow.

Here is exemple of codes :

in html :

<webobject name = "periode" /> Pop 1

<webobject name = "niveau" /> Pop 2, data depends to Pop1

<webobject name = "onChanges" /> WOSubmitButton hidden by css which contain method to refresh pop 2 data 


in wod :

periode : WOPopUpButton {

list = periodes;

item = currentPeriode;

displayString = currentPeriode.libelle;

noSelectionString = "Toutes";

selection = selectedPeriode;

size = "1";

class = "periode";

; action which call method bind to onChange WOSubmitButton

}


niveau : WOPopUpButton {

list = niveaux; ===>data depend to Pop 1

item = currentNiveaux;

displayString =currentNiveaux.libelle;

noSelectionString = "Tous";

selection = selectedNiveaux;

size = "1";

class = "niveau";

}


onChanges : WOSubmitButton {

name = "change";

action = onChang;

class = "hide";

value = "";

}


in Java :

public WOActionResults onChang() {

comboxNiveau(selectedPeriode);

return null;

}

protected NSArray comboxNiveau(EOVuePeriodeParam periode) {

if (periode == null) {

niveaux = EOVueNivAdm.fetchAllEOVueNivAdms(session()

.defaultEditingContext(), niveauOrderings);

} else {

  EOQualifier qual = EOQualifier.qualifierWithQualifierFormat(

"pperiode=%@", new NSArray(periode.primaryKey()));

niveaux = EOVueNivAdm.fetchEOVueNivAdms(session()

.defaultEditingContext(), qual, niveauOrderings);

}

}


...

I want to know if there another way to refresh my pop 2 data without using the _javascript_ which is obliged to submit before refresh?

Thanks
