ERROR deep link code (UrlHelper.UrlGenerator()) in DataEntity.postLoad()

Hello,

I want to populate a deep link to a certain record (in my example SalesTable) via a data entity. Therefore I created an unmapped field (/deepLink/) on the entity and tried to fill it in the /postLoad()/ method:

This is a display method on a custom table creating the deep link URL, which returns the correct value (tested via Form):

public display str getDeepLinkSalesTable()    {        str deepLink;        // gets the generator instance        var generator     = new Microsoft.Dynamics.AX.Framework.Utilities.UrlHelper.UrlGenerator();        var currentHost   = new System.Uri(UrlUtility::getUrl());        generator.HostUrl = currentHost.GetLeftPart(System.UriPartial::Authority);        generator.Company = curext();        generator.MenuItemName = menuItemDisplayStr(SalesTable);        generator.Partition = getCurrentPartition();        // repeat this segment for each datasource to filter        var requestQueryParameterCollection = generator.RequestQueryParameterCollection;        requestQueryParameterCollection.AddRequestQueryParameter(formDataSourceStr(SalesTable, SalesTable), fieldStr(SalesTable, SalesId), this.SalesId);        System.Uri fullURI = generator.GenerateFullUrl();        // to get the encoded URI, use the following code        if (fullURI.AbsoluteUri != //)            deepLink = fullURI.AbsoluteUri;        return deepLink;    }

It is called in the postLoad of a data entity:

public void postLoad()    {        super();        this.DeepLinkSalesTable = CustomTable::find(this.SalesId).getDeepLinkSalesTable();    }

The code compiles well but when running an ODATA GET against the entity I get an CLR error:

Any help would be appreciated.

Thanks in advance

Sebastian

I see that an exception was thrown, but not where and what the error message says. Please use the debugger to get this information. Resolving a problem without enough information is difficult, as you've already found.

Hi Martin,

thanks for the reply. Unfortunatly I'm struggling with the debugger on my image (always "closed unexpectly..."). Therefore I could not extract a detailed error message. The error arises when executing the following line:

Resolve a problem is very difficult without knowing what the problem is.

Can you tell us more about your problem with debugging? Your description isn't clear to me. Are you saying that your breakpoints in postLoad() are ignored? If so, which process did you attach the debugger to? Do you have debugging enabled for the module? Are you able to use debugger for your other code?

These are my debugging options:

My debugging is attatched to "w3wp.exe" and the debugger loads the breakpoint correctly but as soon as I do a ODATA call to the DataEntity via POSTMAN, the debugger crashes:

Unfortunatly, I didn't figured out to get my debugger working. Nevertheless the solution was to use "EnvironmentFactory" instead of "UrlUtility" to get the correct environment URL:

IApplicationEnvironment env = EnvironmentFactory::GetApplicationEnvironment(); str currentUrl = env.Infrastructure.HostUrl; System.Uri currentHostUrl = new System.Uri(currentUrl); UrlGenerator urlGenerator = new UrlGenerator(); urlGenerator.HostUrl = currentHostUrl.GetLeftPart(System.UriPartial::Authority);
