Hi!
Happy new year :)
Here are the code snippets:
--------------
The JSF page:
--------------
...
<h:form>

redisplayed --%>

page is redisplayed --%>
<h:panelGroup>

<%-- the dataTable from which rows are deleted with the button below --%>

var="row"
renderedIfEmpty="true"

</t:column>

<%-- 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
