Zdenek Sochor updated TOMAHAWK-903:
-----------------------------------
Status: Patch Available (was: Open)
> 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
> Attachments: HtmlInputDate.patch
>
>
> 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
