Power Tools generated code causing Exception #9280

TimMackey created 4 years ago

Power Tools version 2.4.0.1 was used to create the following entity and code.

using System;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
using Abp.Domain.Entities.Auditing;
using Abp.Domain.Entities;

namespace ngTTM.TtmDataModel
{
	[Table("TtmExamStates")]
    public class ExamState : Entity 
    {
		[Required]
		public virtual string Guid { get; set; }
		public virtual int ItemsProcesssed { get; set; }
		public virtual int ItemsTotal { get; set; }
		public virtual double MathNotationRenderDuration { get; set; }
    }
}

         public async Task<PagedResultDto<GetExamStateForViewDto>> GetAll(GetAllExamStatesInput input)
         {
            
            var filteredExamStates = _examStateRepository.GetAll()
                        .WhereIf(!string.IsNullOrWhiteSpace(input.Filter), e => false  || e.Guid.Contains(input.Filter))
                        .WhereIf(!string.IsNullOrWhiteSpace(input.GuidFilter),  e => e.Guid == input.GuidFilter);

            var pagedAndFilteredExamStates = filteredExamStates
                .OrderBy(input.Sorting ?? "id asc")
                .PageBy(input);

            var examStates = from o in pagedAndFilteredExamStates
                         select new GetExamStateForViewDto() {
                            ExamState = new ExamStateDto
                            {

                                MathNotationRenderDuration = o.MathNotationRenderDuration,
                                Id = o.Id
                            }
                        };

            var totalCount = await filteredExamStates.CountAsync();

            return new PagedResultDto<GetExamStateForViewDto>(
                totalCount,
                await examStates.ToListAsync()
            );
         }

The table data:

The UI appears as follows:

Clicking the columns for the integer values will sort ascending and descending as expected. Clicking the column for the string value (Guid) causes an Exception on the server. Logs.txt:

The fault occurs on this statement:

            var pagedAndFilteredExamStates = filteredExamStates
                .OrderBy(input.Sorting ?? "id asc")
                .PageBy(input);

Why is generated code not functioning without faults?
What changes need to be made to fix this?
