Second issue is when applied Required attribute on the block type property, I dragged shared block into content area and filled the rest of fields but not that required field, after I clicked done, it still closed windows without showing me up the errors before I published the changes. 

anyone encounter the same issue??

Hello,

I believe that the first issue you described is how they meant it to work.

The editor is presented with the required fields only. Hence, the title "Enter the required information bellow". Before this is entered, the editor can't save and publish. I am not sure why this bothers you, perhaps you see the reason why this is a bad idea? I would just say it works differently than in previous EPi versions. This is the view I am seeing: http://img255.imageshack.us/img255/9681/enterrequiredcontent.jpg

As for the second issue, I could not reproduce this, I am getting the error and I can't save and publish new block that doesn't have a required field filled.

Hi Marija

Thanks for your response. Maybe my initial post and page type didn't make quite sense and wasn't able to help you recreate the problem. Let me dive into more details to explain my problem.

This time I add more properties to my previous page type. In my page type (StandardPage), the 2nd and 3rd title properties are not required.

Firstly I used this page type to create a new page instance, in the edit mode, the 2nd and 3rd titles did not show in the editor which is very confused, check this screenshot http://i46.tinypic.com/2evcj0w.jpg.

Secondly, the whole cms editor css was broken (I can't see the done button at the bottom) because of this page type contains more properties now, that's why you can't reproduce this issue by using the initial post page type. 

Finally, after I created this page instance by hitting the "tab" key to get to "done" button, the 2nd and 3rd title reappeared.

 [ContentType(GUID = "4f654133-7024-4a96-b469-80c5edee06e7")]
    public class StandardPage : PageData
    {
        [Display(
    GroupName = SystemTabNames.Content,
    Order = 300)]
        [CultureSpecific]
        [Required]
        public virtual string Title { get; set; }

        [Display(
    GroupName = SystemTabNames.Content,
    Order = 301)]
        [CultureSpecific]
        public virtual string Title2 { get; set; }

        [Display(
    GroupName = SystemTabNames.Content,
    Order = 302)]
        [CultureSpecific]
        public virtual string Title3 { get; set; }

        [Display(
    GroupName = SystemTabNames.Content,
    Order = 303)]
        [CultureSpecific]
        [Required]
        public virtual string Title4 { get; set; }

        [Display(
    GroupName = SystemTabNames.Content,
    Order = 304)]
        [CultureSpecific]
        [Required]
        public virtual string Title5 { get; set; }

        [Display(
   GroupName = SystemTabNames.Content,
   Order = 305)]
        [CultureSpecific]
        [Required]
        public virtual string Title6 { get; set; }

        [Display(
            GroupName = SystemTabNames.Content,
            Order = 308)]
        [CultureSpecific]
        [Required]
        public virtual XhtmlString ShortDesc { get; set; }


        [Display(
            GroupName = SystemTabNames.Content,
            Order = 310)]
        [CultureSpecific]
        [Required]
        public virtual XhtmlString MainBody { get; set; }

        [Display(
            GroupName = SystemTabNames.Content,
            Order = 320)]
        public virtual ContentArea MainContentArea { get; set; }

        [Display(
          GroupName = SystemTabNames.Content,
          Order = 330)]
        public virtual SimpleBlock SimpleBlock { get; set; }

    }

Hi, sorry for the long answer, I hope you fixed this in the meantime, but if not:

I believe this is a bug in IE.

I can reproduce it, but I could get to work:

Click on the MainBody and press tab a couple of times -> the button and the scroll bar will appear.

Perhaps this should be reported to EPi as a bug.
