An error occurred when processing your submitted information - Custom Controller

I have a page like this

 

<apex:page controller="My_Controller">
  <apex:form >
      <apex:inputField  value="{!foo.bar__c }"/>
       <apex:commandButton value="Search" action="{!search} />
  </apex:form >
</apex:page>

 

 

And my controller

 

public class My_Controller
{
    public Foo__c foo {get; set;}

    public My_Controller()
    {
        foo = new foo__c();
    }

     public PageReference search()
    {
       return null;
    }

}

 

I cannot seem to make a lookup field work on the page.  THe page displays ok, the look up field works.  But when I press the command button I get the error

 An error occurred when processing your submitted information

Does it work if you remove the whitespace after bar__c:

{!foo.bar__c }

Unbelievable - yes it now works

1) I cannot believe I did not try this myself
2) I cannot believe visualforce doesn't trim the string automatically for me.

Unbelievable, I had same problem and wasted a few hours on it. Eventually found the answer here.

I too cannot understand why a trailing space at the end of the expression makes a difference. Why doesnt the compiler trim this?

Out of this world! I have been searching for this solution for hours and it was a space before the end Quote mark for me. Thank you for pointing out the obvious, yet amazingly easy to miss, resolution.
