ValueChangeListener is not working.for disable property

Question

valueChangeListener is not working for disable property with following details. Requirement is to enable to date if from to date is entered.
Field 1:
<af:inputDate value="#{bindings.PrintFromDate.inputValue}"
label="#{bindings.PrintFromDate.hints.label}"
required="#{bindings.PrintFromDate.hints.mandatory}"
shortDesc="#{bindings.PrintFromDate.hints.tooltip}"
id="id2" autoSubmit="true"
*valueChangeListener="#{reprintBean.enableToDate}">*
<f:validator binding="#{bindings.PrintFromDate.validator}"/>
<af:convertDateTime pattern="#{bindings.PrintFromDate.format}"/>
</af:inputDate>
<af:inputDate value="#{bindings.PrintToDate.inputValue}"
label="#{bindings.PrintToDate.hints.label}"
required="#{bindings.PrintToDate.hints.mandatory}"
shortDesc="#{bindings.PrintToDate.hints.tooltip}"
id="id1"
*disabled="#{!requestScope.enableToDate}"*
*partialTriggers="id2"*>
<f:validator binding="#{bindings.PrintToDate.validator}"/>
<af:convertDateTime pattern="#{bindings.PrintToDate.format}"/>
</af:inputDate>
public void enableToDate(ValueChangeEvent valueChangeEvent) {
System.out.println("IN enableToDate");
if (valueChangeEvent.getNewValue() != null) {
FacesContext context = FacesContext.getCurrentInstance();
System.out.println("Enable to Date");
context.getExternalContext().getRequestMap().put("enableToDate",true);
Please suggest me what is wrong on this.

Answer 1

I still not able to achive this. (null the to date value if the FromDate has changed)
<af:inputDate value="#{bindings.PrintFromDate.inputValue}"
label="#{bindings.PrintFromDate.hints.label}"
required="#{bindings.PrintFromDate.hints.mandatory}"
shortDesc="#{bindings.PrintFromDate.hints.tooltip}"
id="id2" autoSubmit="true"
*binding="#{reprintBean.fromDate}"*
*valueChangeListener="#{reprintBean.enableToDate}"*>
<f:validator binding="#{bindings.PrintFromDate.validator}"/>
<af:convertDateTime pattern="#{bindings.PrintFromDate.format}"/>
</af:inputDate>
<af:inputDate value="#{bindings.PrintToDate.inputValue}"
label="#{bindings.PrintToDate.hints.label}"
required="#{bindings.PrintToDate.hints.mandatory}"
shortDesc="#{bindings.PrintToDate.hints.tooltip}"
id="id1"
disabled="#{bindings.PrintFromDate.inputValue eq null}"
binding="#{reprintBean.toDate}"
*partialTriggers="id2">*
<f:validator binding="#{bindings.PrintToDate.validator}"/>
<af:convertDateTime pattern="#{bindings.PrintToDate.format}"/>
</af:inputDate>
Value change method:
public void enableToDate(ValueChangeEvent valueChangeEvent) {
*setToDate(null);*
This method is not able to reset the to date value to null. Please help to find the issue here.
