Playing with a test ECMA2 MA, I've run into a strange problem: after I configure the MA with the "Create Management Agent" dialog, after I configure the last page, the dialog instead of closing and creating the MA goes back to the "Capabilities" page.

I've made a video showing this problem: http://espace.cern.ch/idm/resources/ecma2-capabilities-problem.mp4

I'm getting no error message, and I see nothing in the event log.

Has anyone seen this behavior?

Any suggestion on how to troubleshoot

Hi Paolo,

Are you using any string validation on any of the parameters that you are setting? I would assume that the ParameterValidationResult would be returned when you hit the next button on that screen, but that's at least something to look at.

Thanks,

Mark

Hi Mark,

Thanks for the hint...

It's something related to parameters for sure... it looks like this behavior is triggered by Capabilities parameters.

I have a parameter with validation (not in the capabilities page), but if it fails validation I get (correctly) an error message immediately.

I'll continue the investigation on Monday.

I noticed in your video that you are implementing the IMAExtensible2GetCapabilitiesEX. I've never tried to use that. Is there a specific feature that you need that is not implemented by IMAExtensible2GetCapabilities? If not, you could try the standard capabilities to see if the issue goes away.

Thanks,

Mark

The issues pops up with IMAExtensible2GetCapabilitiesEx, as soon as I define a configuration parameter in the "Capabilities" page. I've tested this on 2 different installations, with the same result (FIM version = 4.1.3510.0).

This is a very simple piece of code that allows reproducing the problem.

Could someone please try to reproduce this?

            MACapabilities myCapabilities = new MACapabilities();
            // configParam.Value == "1"
            // myCapabilities.SupportHierarchy = Convert.ToBoolean(configParameters["SupportHierarchy"].Value);

            throw new NotImplementedException();

    }
}

Everything compiles fine but when I click the refresh interfaces button during the MA creation I get the following error:

If I just press ok, I do get a list of interfaces that looks correct and I am able to successfully create the MA. Editing the MA and selecting refresh interfaces return the same error.

My lab is version 4.1.3559.0

Thanks,

Mark

Looks like my screen cap did not work. It looked fine in the reply window.

Here's the error:

"Unable to retrieve configuration parameters from the extension: Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))

Mark

That's the same error I'm getting after I updated to 4.1.3634.0

I'll try with the non-Ex GetCapabilities interface and see what happens...

With IMAExtensible2GetCapabilities instead of IMAExtensible2GetCapabilitiesEx I get exactly the same error message.

It really looks like something is broken here...

it seems to want some connectivity parameters. If I change your getconfigparameters to this:

IList<ConfigParameterDefinition> GetConfigParameters(KeyedCollection<string, ConfigParameter> configParameters,

ConfigParameterPagepage)

List<ConfigParameterDefinition> configParametersDefinitions = newList<ConfigParameterDefinition>();

switch(page)

caseConfigParameterPage.Capabilities:

ConfigParameterDefinition.CreateCheckBoxParameter("SupportHierarchy", false));

break;

caseConfigParameterPage.Connectivity:

ConfigParameterDefinition.CreateStringParameter("UserID", ""));

ConfigParameterDefinition.CreateEncryptedStringParameter("Password", ""));

ConfigParameterDefinition.CreateStringParameter("Domain", ""));

break;

returnconfigParametersDefinitions;

Many thanks for your help, Mark.

To summarize, it looks like the looping to the Capabilities page was a bug in version 4.1.3510.0.

Updating to the latest hotfix solved the problem, but apparently there's another bug that causes a "catastrophic failure" message to pop up if no Connectivity parameters are provided.

I still think that ECMA2 Management Agents development is quite painful.
