Format Date in Visual Force page

I need Help converting 2016-01-08T19:00:00 to 01/08/2016

I want to truncate the time (19:00:00 )

This is what I wrote:
  
<apex:column headerValue="Event Date">
                           <apex:outputText value="{0,date,MM'/'dd'/'yyyy}">
                            <apex:param value="{!listMysticsmailMap[m].eventDateTime}" />
                        </apex:outputText>
                     </apex:column>



However, I get the following error: Content cannot be displayed: The value attribute on <apex:outputText> is not in a valid format. It must be a positive number, and of type Number, Date, Time, or Choice.

I then tried
  
<apex:outputText value="{0,date,MM/dd/yyyy}">



That didn't work either

Hi Gavin,

It seems that issue is not with apex:outputText. I think your map is creating problem here. I am wondering if this works with map collection in visualforce pages. Can you try this with creating a simple datetime variable in wrapper or some other way around this.

Hi Gavin,

Just a little modification in your code. 
<apex:column headerValue="Event Date">
                           <apex:outputText value="{0,date,MM/dd/yyyy}">
                            <apex:param value="{!listMysticsmailMap[m].eventDateTime}" />
                        </apex:outputText>
                     </apex:column>

Let me know if it works for you.

Regards,
Naval

Hi Naval,

Thank you for looking into my formatting challenge. I did try that and it still gave me the error "Content cannot be displayed: The value attribute on <apex:outputText> is not in a valid format. It must be a positive number, and of type Number, Date, Time, or Choice."

I think the conversion is failing because  2016-01-08T19:00:00 <-- this time element

I need to convert to MM/dd/yyyy  or truncate the T19:00:00 

Any advice on this will be greatly appreciated

You are right Naval. I have declared eventDateTime as string 

public String eventDateTime{get;set;}

So its trying to convert a string into date. So if I declare the eventDateTime Map to return a date value, would it work?

Hi Gavin,

You can give it a shot but sometimes this formatting doesn't work with Maps.

Thanks,
Naval
