Question

I have a dropdown that holds an account number and two date fields. I want to reset the date fields if I change the value of the dropdown. I also have a search button that make a query using these fields (account #, from date, to date).

<fieldset>
    <p:selectOneMenu id="account_search" value="#{accountHistoryBean.account}" converter="accountConverter">
        <f:attribute name="itemsList" value="#{accountHistoryBean.userAccounts}"/>
        <f:selectItems value="#{accountHistoryBean.userAccounts}" var="account" itemLabel="#{account.number}" itemValue="#{account}"/> 
        <p:ajax update="start_date_search, end_date_search" event="change" actionListener="#{accountHistoryBean.resetDates}" process="account_search"/> 
    </p:selectOneMenu>
<fieldset>

<fieldset>
    <p:calendar value="#{accountHistoryBean.fromDate}" id="start_date_search" pattern="dd/MM/yyyy"/>
</fieldset>

<fieldset>
    <p:calendar value="#{accountHistoryBean.toDate}" id="end_date_search" pattern="dd/MM/yyyy"/>
</fieldset>



<fieldset>
    <p:commandLink styleClass="regular_button" action="#{accountHistoryBean.search}" update=":search :accountHistoryList :accountHistoryList:accountHistTable" >
        <span>#{msj.search}</span>
     </p:commandLink>
 </fieldset>

If I do the following:

1. Change “from Date” and “to Date” fields
2. Change account field (dropdown with ajax).

Then the dates are resetted to their default value.

But if I do the following:

1. Change “from Date” and “to Date” fields to DATEX AND DATEY
2. Press search
3. Change “from Date” and “to Date” fields to DATEX2 AND DATEY2
4. Change account field (dropdown with ajax).

Then it changes the Date field to DATEX and DATEY (not the default values).

The methods in the Bean are the following:

public void resetDates()
{
    Calendar calendar = GregorianCalendar.getInstance();
    //By default set toDate as 3/3
    calendar.set(Calendar.MONTH, 2);
    calendar.set(Calendar.DAY_OF_MONTH, 3);
    toDate = calendar.getTime();
    //By default fromDate is one month earlier
    calendar.setTime(toDate);
    calendar.add(Calendar.MONTH, -1);
    fromDate = calendar.getTime();
}

public String search(){
    //Just update the filters
    lazyDataEntityModel.setUpdateData(true);
    return null;
}

Any help?

I changed

<p:ajax update="start_date_search, end_date_search" 
        event="change" 
        actionListener="#{accountHistoryBean.resetDates}"
        process="account_search"/> 

For

<p:ajax update="start_date_search, end_date_search" 
        event="change"
        listener="#{accountHistoryBean.resetDates}" 
        process="account_search"/> 

and it worked.

Thanks
