| I getting a very reproducible (on my side anyway) error side when attempting to access some data via ES. Other data is accessed fine. Here is the error reported to the client:
BusinessLayerException
An error occurred while refreshing the data from field 'ProjectOrganizationBO.Owner' to property 'Text' on control 'txtOwner.'
BusinessLayerException
An error occurred while refreshing property 'Text' to control 'txtOwner'
TargetInvocationException

Bad Data.

ArgumentNullException

Parameter name: graph
Source : mscorlib

Some info about what is going on:
- This error does not happen if I connect directly.
- If I step through the code, the error occurs on the line that fills the data table of the BO.
- The Owner property is actually a custom property that is doing a separate ExecuteScalar command to get that value.
- txtOwner is bound to the Owner property.
Any ideas why this isn't working with ES? |

| | One more thing...the ExecuteScalar could and is likely returning Nothing, as there is often no row found. On the client I'm checking for Nothing and DbNull.Value. |

| | Yep, this was the bug that we mentioned in class... It's not that we're testing on DBNull.Value, it's that we're not testing at all and just trying to serialize the returned value, which is nothing... Here are the DLLs that you need to fix it. Copy them to the bin\ folder of your enterprise server and either restart IIS, recycle the application pool, or stop and start the website.

| Thanks Ben! I missed that this was a current ES bug.
I copied the dlls to the server, restarted IIS. Now I'm getting bad data error. (CrypographicException).
I checked the keys and they match. Did the public tokens change on the dlls? Did I not get IIS reset enough? |

| | As a test, I turned off encryption and now I get EndOfStreamException. |

| | OK, here are all of the DLLs that are part of the server, just in case another one of them changed. [Edit: removed attachment]

| | OK, well Greg, it wasn't a problem with the ES, it was a problem with the operator... I never created the proper project configuration for the Dotfuscator project, so if I built it in debug and then built the solution, it would create the proper DLLs for you. So, I've been sending you the same version over and over again... So, here are the fixed DLLs  Give them a shot and let me know how it works...
