Hi Murali,

Hi Murali,

I'm having a similiar problem with one of my customers. We haven't been able to resolve it but we have found a way around it, I'd like to do more testing but my customer justs wants to get on with it now that we have a workaround. Logging a call with Microsoft can be expensive, most businesses have a finite amount of support hours so you really have to do your homework before you starting chewing those hours up.

Problem Description:

Customer created a custom list with two calculated columns and various choice, string and multi-string columns. Customer was attempting to copy and paste 128 rows of data into each column from a spreadsheet. The first (title) column successfully pasted 128 values.

Subsequent columns would paste the values but not allow the values to be committed as every row displayed the "Unable to Communicate with the Server" message, preventing the list from being saved.

Workaround:

The problem appears to be related to the number of items the customer is trying to paste during each operation and the relationship this has with the calculated columns. We found that when we pasted 70 or less items in one operation we did not receive the error. I attempted pasting 128 rows of data into a seperate list with the same columns excluding the calculated columns, and was successfully able to paste all 128 rows.

For the problem list I suggested to the customer to copy the formula's from the calculated columns, delete these columns and then trying pasting again, he didn't like the idea as he's happy to paste in 50% chunks. Based on the fact I was able to paste without any problems on a list without calculated columns I would suggest it's related.

So my questions for you are:

1. Are you trying to paste/add multiple values at once?
2. Do you have any special column types, i.e. calculated or lookup columns?
3. What columns do you have in your list?
4. Have you tried adding the entries in using form entry instead of grid entry?

Unforunately I don't know how generic this error message is, there is absolutely nothing in my ULS logs or event viewer. If this error is specific to submitting data to a list in grid view it would make it easier to diagnose, but if the error is generic in nature your problem could be as obscure as the FBA configuration.

I hope this information helps you, I will try and do some more testing.

Being +2 months I guess there is no fix for this.  I wonder (HOPE) that it might be in the October 2013 CU but I am BY NO MEANS holding my breath!  For me, when you release a product and you don't do testing like this, it is STILL in BETA and or when you want people (BUSINESS) to use it, it BETTER WORK!  To call it "QUICK" and have it be abhorently SLOW or not work AT ALL, is a HUGE Failure!  I know as a manager, I'd put my focus on this! 

Sadly I have found a LOT of problems with Microsoft's SharePoint 2013 product and it is frustrating.  You say you have a lot of good stuff but it is annoying to have them NOT work.

Did any one find an answer to this one?

I have a similar problem with a vanilla Project Timeline and the tasks behind it.  When I go to edit one of the tasks it returns the Unable to Communicate with the Server error.  The environment I'm building is meant to be a showcase of what SharePoint 2013 can do, so far (even following the authorised texts) it's turning into a "what SharePoint 2013 cannot do" showcase.

Thanks

The problem I'm experiencing appears to be related to IE11, as opening the same page via IE8 all works as expected

Although incompatibility awaiting a fix in the next IE Service Pack - I suspect.

Does running in compatiblity mode help on IE 11?

We are on IE 9 and some people are on IE 8, not sure if company will go to IE 10 any time soon.  For me, expecting IE 11 is like wanting a pay raise! :)
