Steps to reproduce in Alloy Site

1. Change Buttonblock to use [RequiredCustom] attribute.
2. Recompile.
3. In editmode, create a new buttonblock.
4. Publish it right away,
5. Get a validation warning.
6. Enter some text to ButtonText and try to publish again.
7. The publish button is gone.

[AttributeUsage(AttributeTargets.Property | AttributeTargets.Field | AttributeTargets.Parameter, AllowMultiple = false)]
public class RequiredCustomAttribute : ValidationAttribute
{
/// <summary>
/// Gets or sets a flag indicating whether the attribute should allow empty strings.
/// </summary>
public bool AllowEmptyStrings

{ get; set; }
public override bool IsValid(object value)
{
if (value == null)
{ return false; }
// only check string length if empty strings are not allowed
var stringValue = value as string;
if (stringValue != null && !AllowEmptyStrings)
{ return stringValue.Trim().Length != 0; }
return true;
}
}
