Changing the rendered "state" of inputDate causes a NullPointerException
------------------------------------------------------------------------
Key: TOMAHAWK-903
URL: https://issues.apache.org/jira/browse/TOMAHAWK-903
Project: MyFaces Tomahawk
Issue Type: Bug
Components: Date
Affects Versions: 1.1.5-SNAPSHOT
Environment: Tomahawk 1.1.5 SNAPSHOT of February 19th 2007, JSF 1.2_2
RI, J2EE 1.5
Reporter: Bjørn Stenfeldt
I have a boolean checkbox, which toggles the rendered attribute on 2 inputDate
tags. When I check the "continuous" checkbox, the page refreshes and the
"begins" and "ends" inputDate tags are not rendered. But when I uncheck the
checkbox, I get an exception. I have tried to replace the inputDate tags with
inputText tags and that works just fine. Everything seems to indicate a problem
with inputDate.
Here's the code I'm using, along with the exception thrown.
My JSF:
<html:form id="myForm">
<tomahawk:selectBooleanCheckbox id="continuous"
value="#{ManagedBean.continuous}"
onclick="document.forms['myForm'].submit();"
immediate="true"/>
<html:outputText rendered="#{!ManagedBean.continuous}">
<tomahawk:inputDate id="begins" value="#{ManagedBean.begins}"
required="true"/>
<tomahawk:inputDate id="ends" value="#{ManagedBean.ends}" required="true"/>
</html:outputText>
</html:form>
My ManagedBean:
public class ManagedBean extends AbstractRequestBean {
private boolean continuous;
private Date begins;
private Date ends;
public ManagedBean() {
String value = null;
if ((value = getRequestParameter("myForm:continuous")) != null) {
continuous = value.equalsIgnoreCase("true");
}
else {
continuous = false;
}
}
public boolean getContinuous() {
return continuous;
}
public void setContinuous(boolean continuous) {
this.continuous = continuous;
}
public Date getBegins() {
return begins;
}
public void setBegins(Date begins) {
this.begins = begins;
}
public Date getEnds() {
return ends;
}
public void setEnds(Date ends) {
this.ends = ends;
}
}
Exception thrown:
java.lang.NullPointerException
