AW: AW: EditableValueHolder rendering behavior / Restore View
Hi!
Happy new year :)
Here are the code snippets:
--------------
The JSF page:
--------------
...
<h:form>
...
<%-- the inputTextarea which is rendered empty again after the JSF page is
redisplayed --%>
<h:panelGroup>
<h:outputLabel for="fragetext"
value="Frage*: "

</t:inputTextarea>
<f:verbatim><br/></f:verbatim>
<h:message for="fragetext"
styleClass="error"
lang="de"
title="Fehlermeldung für das Frage Textfeld" />
</h:panelGroup>
<%-- the selectBooleanCheckbox which is rendered empty again after the JSF
page is redisplayed --%>
<h:panelGroup>
<h:outputLabel for="mussFrage" value="Antwort erforderlich: "
styleClass="formLabel"
lang="de"
title="Auswahlfeld zur Angabe, ob die Antwort erforderlich ist" />
<t:selectBooleanCheckbox id="mussFrage"

<h:outputText escape="false" value=" Ja, Frage muss beantwortet
werden"

<f:selectItems

</t:selectOneRadio>
</t:column>
<%-- the inputText which is NOT rendered empty again after the JSF page is
redisplayed (the value entered is rendered) --%>
<t:column>
<t:radio for="auswMoeglichkeitRadios" index="0" />

<f:verbatim><br/></f:verbatim>
<h:message for="anzahlSpalten"
styleClass="error"
lang="de"
title="Fehlermeldung für das Spaltenanzahl Textfeld" />
</t:column>
<t:column>
<t:radio for="auswMoeglichkeitRadios" index="1" />
</t:column>
</h:panelGrid>
<%-- the dataTable from which rows are deleted with the button below --%>
<t:dataTable id="dataTableAuswahlmoeglichkeiten"
binding="#{EinfAuswFrageBacking.dataTable}"
value="#{EinfAuswFrageBacking.auswMoeglichkeitenModel}"
var="row"
renderedIfEmpty="true"
preserveDataModel="false">
<t:column width="30">
<t:selectBooleanCheckbox binding="#{EinfAuswFrageBacking.checkbox}"
required="false"
lang="de"
title="Auswahlmoeglichkeit auswählen zum Löschen"
immediate="false" />
</t:column>
...
</t:dataTable>
<%-- the action button to delete rows with --%>
<h:commandButton value="Auswahl Entfernen"
action="#{EinfAuswFrageBacking.deleteAuswMoeglichkeiten}"
immediate="true" />
...
</h:form>
...
-----------------------------------------------------------------
The action method of the EinfAuswFrageBacking.java Backing-Bean:
-----------------------------------------------------------------
public String deleteAuswMoeglichkeiten() {
List toDelete = this.getSelectedAuswMoeglichkeiten();
Iterator it = toDelete.iterator();
while (it.hasNext()) {
this.auswMoeglichkeitenList.remove(it.next());
}
int size = this.auswMoeglichkeitenList.size();
for (int i = 0; i < size; i++) {
Auswahlmoeglichkeit am =
(Auswahlmoeglichkeit)this.auswMoeglichkeitenList
.get(i);
am.setAuswahlindex(new Integer(i + 1));
}
this.checkbox.setSelected(false);
return Constants.ACTION_SUCCESS;
}
----------------
faces-config.xml:
----------------
<navigation-rule>
<from-view-id>/Management/Fragen/EinfAuswFrage.jsp</from-view-id>
<navigation-case>
<from-action>#{EinfAuswFrageBacking.deleteAuswMoeglichkeiten}</from-action
>
<from-outcome>success</from-outcome>
<to-view-id>/Management/Fragen/EinfAuswFrage.jsp</to-view-id>
</navigation-case>
</navigation-rule>
By the way: the inputTextarea is not the only component which is rendered
empty when the page is redisplayed after submitting it non-empty - it also
happens to the selectBooleanCheckbox, and to the selectOneRadio, but not to
the inputText, which renders the value entered before submitting the page
(In my last email, I spuriously wrote that the inputText is rendered empty,
but it actually was an inputTextarea!).

Matthias

Posted by Matthias Kahlau <mk...@web.de>.

Matthias

Re: AW: AW: EditableValueHolder rendering behavior / Restore View
Posted by Volker Weber <us...@weber-oldenburg.de>.
Hi Matthias,
i think the problem is the return value of your action method.
I'm not really sure, so please correct me if the following is incorrect.
If a action method returns a value != null the navigation cames in, then
a new view is created, also if the new viewId is the same as the old
one. If the action method returns null the old view is rerendered.
The reason for persistent value in one of your components is the
component binding.
Try returning null in deleteAuswMoeglichkeiten().
Regards
Volker

Don't answer to From: address!
Mail to this account are droped if not recieved via mailinglist.
To contact me direct create the mail address by
concatenating my forename to my senders domain.
