Devart Forums

I get the same error in Oracle. I imagine this problem extends to all the databases.

It seems to work for some projects and not others. I haven't been able to detect a pattern yet. I will keep trying to narrow it down.

Have you selected any project in your Solution Explorer when running Upgrade Wizard? If yes, please specify the type of this project.

Yes, it is selected in the Solution Explorer of Visual Studio 2010 SP1. Project Type is WPF Application.

I know what Lazy Loading is. My point is that I'm getting different behavior between changing the LazyLoadingEnabled to false on the model and changing it programattically. It should behave the same for both.

using Devart.Data.Oracle.Entity version 6.10.141.0

I'm using some includes to use eager loading. This seems to only work when LazyLoadingEnabled is set to false in the model itself.
If the model has LayLoadingEnabled = true and I set it to false in the below code where I'm doing my queries, it doesn't work. I don't want to disable lazy loading on the model as I only want to use eager loading in a few cases. Are there any workarounds?

ctx.ObjectContext.ContextOptions.LazyLoadingEnabled = false;
var data = ctx.ObjectContext.FullyLoadedCosts.Include("FlcCategory").Include("Transportation").Where(e => regionRoles.Contains(e.Region));

I don't know if this is even feasible, but it would be really nice if we could compress the data going back and forth between Oracle. We have a number of users accessing via wireless VPN and it is slow. I've done everything I can to eliminate data that we don't need, but if it could be compressed, that would make a huge difference.

Keep up the good work.

The solution was to manually go into the license.licx file and update the version listed to the latest version and save the file. Wizards function correctly afterwards.
I would say this is definately a bug, but at least I have a work around.

I am unable to run either the devart migration wizard or the ubgrade wizard. I get the following "Unable to start wizard. No project selected."

I am running VS2010sp1 on win 7 64x

trying to upgrade to 6.10.135.0

Projects are also targetting .Net Framework 4

With the announcement that Microsoft is coming out with EF 4.1, what are devarts plans concerning this latest version?

Yes 6.10.110 worked

Looks like the 6.10.111 driver is supposed to fix this. We shall see.

On Oracle Linq I'm getting the following error trying to update a detached entity.

Getting An entity can only be attached as modified without original state if it declares a version member or does not have an update check policy.

I have set Update Check Policy to Never for all columns except the primary key, which it won't let me change.

This is with driver version 2.20.11.0 and used to work with older drivers.

I cannot add a version column as I am not allowed to change the structure of the table.

I get the following error

Generating the model took 00:00:01.5647411.
Unable to generate the model because of the following exception: 'An error occurred while executing the command definition. See the inner exception for details.
Can't found Project
'.

Could you provide an example of this. I can't find it in my file.

To resolve this, I had to create another entity class containing just the columns I wanted to import and used that. It works, though it clutters and complicates the data model.
