After updating to v6.1 from 6.0 p:calendar does not submit selected value, throws throws NullPointerException

[nbs]

Before the application page is displayed I have initialized some items and put them in conversationscope using current request context.

Code: Select all

public void initializeParams() {
        RequestContext context = RequestContextHolder.getRequestContext();
        Date listFromDate = null;
        Date listUptoDate = null;
        String searchParam = "";  

        context.getConversationScope().asMap().put("listFromDate", listFromDate );
        context.getConversationScope().asMap().put("listUptoDate", listUptoDate );
        context.getConversationScope().asMap().put("searchParam", searchParam);
        context.getConversationScope().asMap().put("selectedBudget", null);  
        context.getConversationScope().asMap().put("costcenter", null);
    }

Code: Select all

<p:calendar value="${listFromDate}" pattern="dd/MMM/yyyy" showOn="button" size="11" style="float: right" 
                                            autocomplete="false" showButtonPanel="true" navigator="true" disabled="${searchByid}" >
<p:autoComplete id="branchCombo" value="#{costcenter}"
                                                completeMethod="${costcenterController.completeActiveCenters}"
                                                var="cc" itemLabel="#{cc.description}"
                                                itemValue="#{cc}" converter="${costcenterConverter}" 
                                                dropdown="true" forceSelection="true" scrollHeight="100" disabled="${!globalUser}">
                                            

If I select a date on the calendar and submit the form I get bellow NullPointerException error, but if I submit the form without selecting the calendar (only autocomplete selected) I don't get any error

Primefaces 6.1
Spring Webflow 2.4.7
California Theme

Can you try 6.2 instead of 6.1?

[nbs]

It still behaves the same way with 6.2

Any updates on this?

try 7.0
also the NPE is from spring, try to debug yourself and find out what happens
