Missing Method when trying to go to page for entity with a 1-n navigation property #5703

I have a new 7.3.2 project with a new module. The module has 2 entities CustomTests and CustomTestCategory with the latter being a 1-n property on CustomTests. Whenever I try to load the CustomTests incdex page, I get an error message in the following method in the Index.cshtml.cs file.

When stepping through the code, it seems the GetCustomTestCategoryLookupAsync methos is the problem.

public async Task OnGetAsync()
{
    CustomTestCategoryLookupList.AddRange((
            await _customTestsAppService.GetCustomTestCategoryLookupAsync(new LookupRequestDto
            {
                MaxResultCount = LimitedResultRequestDto.MaxMaxResultCount
            })).Items.Select(t => new SelectListItem(t.DisplayName, t.Id.ToString())).ToList()
    );

    await Task.CompletedTask;
}

Provide us with the following info:

  • ABP Framework version: v7.3.2
  • UI Type: MVC
  • Tiered (for MVC) or Auth Server Separated (for Angular): no
  • Exception message and full stack trace:
  • Steps to reproduce the issue:
  • An unhandled exception occurred while processing the request.

    Hello chris.b@mindmill.co.uk,

    Could you please add below code and try to resolve it. After adding this code it works at my end.

    1. index.cshtml.cs 
     public async Task OnGetAsync()
    {
        CustomTestCategoryLookupList.AddRange((
                await _customTestsAppService.GetCustomTestCategoryLookupAsync(new LookupRequestDto
                {
                    MaxResultCount = LimitedResultRequestDto.MaxMaxResultCount
                })).Select(t => new SelectListItem(t.Name, t.Info)).ToList()
        );

        await Task.CompletedTask;
    }
    1. CustomTestsAppService 
    public async Task<List<CustomTestCategoryDto>> GetCustomTestCategoryLookupAsync(LookupRequestDto input)
        {
            var query = _dbContext.Set<CustomTestCategory>().AsQueryable();

            var categories = await query
                .Take(input.MaxResultCount)
                .ToListAsync();

            return categories.Select(c => new CustomTestCategoryDto
            {
                Name = c.Name,
                Info = c.Info
            }).ToList();
        }
    1. Add this line to ConfigureServices in WebModule
    context.Services.AddTransient<ICustomTestsAppService, CustomTestsAppService>();

    Please do let me know if anything else is needed.

    Thank You, Anjali

    I was able to get it working with your workaround. This however did not show the cause of the problem, so I started stepping back one change at a time.

    I removed the AddTransient code first, then I reverted back to the PagedResult return type.

    I reverted back to the old code in indexcshtml.cs and in the end I was left with the following change.

    In the end my only changes were:

    1. In my CustomTestAppService, I changed
    var lookupData = await query.PageBy(input.SkipCount, input.MaxResultCount).ToDynamicListAsync<CustomTestCategory>();

    to

    var lookupData = await query.PageBy(input.SkipCount, input.MaxResultCount).ToListAsync();

    and 2) added

    using Microsoft.EntityFrameworkCore;

    I think the issue here is around this method ToDynamicListAsync

    This became and issue after I added a Module to the solution that was originally built with 6.0.2 and upgraded to 7.3.2

    The error is resolved, but the issue still needs investigation as this will happen with any new entities created.

    Further investigation of the ToDynamicListAsync method shows the new module uses System.Linq.Dynamic.Core v 1.2.18 as opposed to the latest 1.3.4.

    Upgrading the package fixed the issue.

    This was a new module created by the latest version of ABP Suite. V1.2.18 is marked as Vulnerable. This may need to be fixed in the Project Templates.

    Thanks for reporting. We have already upgraded the package version to v1.3.3 in 7.4.0-rc.1:
