Windows 8 Visual Studio 2012 Issues

Windows 8 Visual Studio 2012 Issues

Postby RonL » Thu 08 Nov 2012 16:35

Hello Devart,

I have used the dotConnect for MySQL successfully for a year with Windows Vista / Visual Studio 2010 Dynamic Data and dotConnect for MySQL 6.60.

I just upgraded to Windows 8 / Visual Studio 2012 Dynamic Data and dotConnect for MySQL 7.20, and I'm sorry to say, I can't get it to work with inserts, updates, and deletes.

Unhandled exception at line 885, column 13 in
http://localhost:2274/ScriptResource.axd?d=UofMq0eVoygSP6BvmvJCy_GkFdqa25yw98KoKNqjZmqSUkISRNDGhJ0T6yxbA6ySAS-tca8DGXd35F5gNqO7iUziE2gkjZ4rB_YY-27s3YAGE5ZwB6v7TI2ORczCdtIgtaGngpaSDdClLENMiwgQSCGxKTJx14xsNYNlrRIDevV2YUN_BzkRHZJXlzNj94IH0&t=6119e399

0x800a139e - JavaScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Row not found or changed.

Full projects pointing to a simple table with two columns have been uploaded as Request Support tickets with dotConnect for MySQL 7.20 builds 104 and 114.

Any tips?

Sorry for the delay. These are known issues. The fix will be available in the next build of dotConnect for MySQL, which we plan to release in several days. We will inform when it is available for download.

Hi Mariial,

Thank you for the latest build. Unfortunately, I'm seeing a new error when trying to Insert / Update / Delete on Windows 8 / Visual Studio 2012 (x64 machine).

Debug is below, and a full Visual Studio project with step-by-step pictures in a Word document has been uploaded to the "Request Support" tickets.

Please advise.

Kind regards,

Ron

Thank you for the test project.
This error occurs in case the Binary Logging mode is set to STATEMENT and a transaction is started with isolation level set to READ COMMITTED. This isolation level is necessary for LINQ to SQL internal transactions. So, the solution is to set the binary logging to "ROW" or "MIXED".

For more information about binary logging please refer to http://dev.mysql.com/doc/refman/5.5/en/binary-log-formats.html

If the previous variant is not possible, you could try using explicit transactions with the necessary Isolation Level.
For example:

Code: Select all
YourDataContext context = new YourDataContext();
context.Connection.Open();
// open transaction with some IsolationLevel
context.Transaction = context.Connection.BeginTransaction(System.Data.IsolationLevel.Serializable);
....
// make inserts, updates, deletes here
....
context.SubmitChanges();

// commit transaction
context.Transaction.Commit();

For more information please refer to:
http://www.devart.com/linqconnect/docs/Transactions.html#explicit

Please notify us about the results.

Hi Mariial,

Thank you for the reply.

I was a bit confused on where to apply the following at the code level (willing to listen to more ideas), so I tried at the database level with partial success, partial failure.

The INSERTs / UPDATEs now work.

The DELETEs return the following, and the table rows have primary keys (PK).

Appreciate the progress. Any tips on DELETEs?

Ron

I was a bit confused on where to apply the following at the code level (willing to listen to more ideas), so I tried at the database level with partial success, partial failure.

To be able to make the code above working for you, you could define the partial method OnCreate() for your DevartqaDataContext class by adding this code into it (e.g. the code with opening a transaction with some IsolationLevel).
To ensure that transactions are committed after submitting changes, you could extend the virtual method SubmitChanges() with the code that will commit the transaction.

As for the "Row not found or changed" exception, it occurs because Dynamic Data runtime fails to set the 'Id' property, as no setter method is defined. We will investigate it and inform you about the results.
To avoid it, please clear the "Read Only" check box for the "Id" property of the "DevartListTable" entity.

Please tell us if this helps.

Hi Mariial,

Thank you for the replies.

A new Visual Studio 2012 Dynamic Data project using 7.2.122 has been uploaded into the "Request Support" area.

* To correct my earlier reply, it's the UPDATEs and DELETEs that are producing the "Row not found or changed".

This new project is using a new MySQL database with the desired Binary Logging mode and the appropriate properties for the Id column.

Any tips?

Kind regards,

Ron

Thank you for the sample project. As we have said earlier, the "Row not found or changed" exception occurs because Dynamic Data runtime fails to set the 'TestTableId' property, as no setter method is defined.
To avoid it, please clear the "Read Only" check box for the "TestTableId" property of the "TestTable" entity in your model (in the window, opened by double-clicking the "TestTableId" property).
JIC: we couldn't reproduce this issue after we have cleared the "Read Only" check box for the "TestTableId" property in your sample project.

Please tell us about the results.

Hi Mariial,

Thank you for the reply.

* UPDATEs / DELETEs now work, after manually clearing the "Read Only" check box (or Read Only = False) for the primary key.

The surprise is that the "Read Only" is checked by default in 7.2.122 via "Entity Developer: Create Model Wizard" (with "Database First" checked) and "Update Model From Database..." (with "Recreate Model" checked).

My Devart request is hopefully a simple one:

* Would Devart be willing to uncheck the "Read Only" by default via "Entity Developer: Create Model Wizard" (with "Database First" checked) and "Update Model From Database..." (with "Recreate Model" checked) for primary keys? [Such would match the Windows Vista / Visual Studio 2010 Dynamic Data and dotConnect for MySQL 6.60 behavior.]

Kind regards,

Ron

Please make sure that after clearing the "Read Only" check box for the primary key ('TestTableId' property) you are saving the changes to the model and the code for it is re-generated.

As for the setting "Read Only" to 'true' for the auto generated values, this is the correct behavior for MySQL. The "Read Only" is always set to 'true' for autoincrement fields when creating a new model or updating an existing one with the "Recreate Model" option.
Please use the 'Update Model From Database' wizard without selecting the "Recreate Model" check box to retain manual changes you have made to your model and to select only the necessary changes to be applied.

Hi Mariial,

Thank you for all your replies.

I consider this issue as successfully closed with the 7.2.122 release.

As for a future design request:

* The default behavior prevents DELETEs and UPDATEs with the Visual Studio 2012 "Entity Developer: Create Model Wizard" (with "Database First" checked) and "Update Model From Database..." (with "Recreate Model" checked). As a request, would Devart consider changing the default behavior to allow DELETEs and UPDATEs (setting Primary Keys to Read Only = False).

From a developer perspective, the Dynamic Data capabilities are really cool when they work. I was a bit lost on why the DELETEs and UPDATEs didn't work by default with 7.2.122 until your post.

Thank you again for all your replies.

Kind regards,

Ron

We have changed the behavior with setting autoincrement primary keys to Read Only = True by default. It will be included in the next build of dotConnect for MySQL. We will inform you when it is available for download.
As a workaround, you could clear the 'Read Only' check box for your autoincrement primary keys manually in the model.
