Nick Belaevski resolved RF-5592.
--------------------------------
Resolution: Rejected
Assignee: Tsikhon Kuprevich
That's not a bug. Value of input is not saved in model due to
bypassUpdates="true" thus causing rendering of old model value. ui:repeat just
do not update page content (also this won't work with ajaxSingle component), while
a4j:repeat does that. That's why ui:repeat seems to be working. Consider the following
code:
import java.util.Arrays;
import java.util.List;
public class RF5992 {
private List<String> texts = Arrays.asList(new String[] { "First" });
public List<String> getTexts() {
return texts;
}
public void setTexts(List<String> texts) {
this.texts = texts;
}
public long getTime() {
return System.currentTimeMillis();
}
}
<h:form>
<ui:repeat value="#{rf5992.texts}" rowKeyVar="index">
<h:inputText id="text" value="#{rf5992.texts[0]}">
<a4j:support ajaxSingle="true" event="onchange"
reRender="text, outputText"
bypassUpdates="true" />
</h:inputText>
<h:outputText id="outputText" value="#{rf5992.time}" />
</ui:repeat>
</h:form>
Compare value of time text when a4j:repeat and ui:repeat are used.
User is unable to update the text in the input field, if this field
is inside of <a4j:repeat> and <a4j:support> is used to re-Render that field

Key: RF-5592
URL: https://jira.jboss.org/jira/browse/RF-5592
Project: RichFaces
Issue Type: Bug
Affects Versions: 3.2.2
Reporter: Igor Dikhtyaruk
Assignee: Tsikhon Kuprevich
example:
xhtml:
<a4j:repeat value="#{myBean.texts}" rowKeyVar="index">
<h:inputText id="text" value="#{myBean.texts[index]}">
<a4j:support
ajaxSingle="true"
event="onchange"
reRender="text"
bypassUpdates="true"/>
</h:inputText>
</a4j:repeat>
Java bean:
package au.gov.austrac;
import java.util.Arrays;
import java.util.Date;
import java.util.List;
import org.jboss.seam.ScopeType;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.Scope;
@Name("myBean")
@Scope(ScopeType.SESSION)
public class MyBean {
private List<String> texts = Arrays.asList(new String[]{"First"});
public List<String> getTexts() {
return texts;
}
public void setTexts(List<String> texts) {
this.texts = texts;
}
}
BTW,
the following works well:
<ui:repeat value="#{myBean.texts}">
<h:inputText id="text" value="#{myBean.texts[0]}">
<a4j:support
ajaxSingle="true"
event="onchange"
reRender="text"
bypassUpdates="true"/>
</h:inputText>
</ui:repeat>
