Value 'Mon Sep 30 00:00:00 GMT 2013' cannot be converted from Text to com.force.swag.soap.DateOnlyWrapper

Question

I am trying to update a task from a visualforce page that I made but kept getting this error below:

"Value 'Mon Sep 30 00:00:00 GMT 2013' cannot be converted from Text to com.force.swag.soap.DateOnlyWrapper."

Anyone knows how to solve it?

Hi Jason,

This is a known error of salesforce. Refer the below link and the possible workaround for it (suggested by salesforce)

Summary

apex:inputHidden can not handle Date(and Datatime) type variable correctly.

Repro

1) Create the following Apex class

public class W2947254 {

public Date dateValue { get; set; }

public W2947254() {

dateValue = Date.today();

}

public PageReference doTest() {

return null;

}

2) Create the following Visualforce page:

Name : W2947254

<apex:page controller="W2947254">

<apex:pageMessages ></apex:pageMessages>

<apex:form >

<apex:inputHidden value="{!dateValue}" />

<apex:commandButton value="TEST" action="{!doTest}"/>

</apex:form>

</apex:page>

3) Access to the above VF page. You will see "TEST" button.

4) Click "TEST" button. You will see the following error message

Error:

Value 'Thu Feb 25 00:00:00 GMT 2016' cannot be converted from Text to com.force.swag.soap.DateOnlyWrapper

This is unexpected.

Workaround:

Use converted string value from Date type for apex:inputHidden instead of using Date type directly

OR

If using SObject's Date type field, this behavior can be avoided by using apex:inputField instead as follows:

<apex:inputField value="{!case.Today__c}" id="hiddenField" style="display: none" showDatePicker="false"/>

Please mark this as best answer if it helps.
