Current behavior

I'm trying to interect two classes to obtain a dto like that:

export class QueryPageDto extends IntersectionType(PartialType(OmitType(CreatePageDto,['metafields','translations'])),PaginationDTO) {}

export default class PaginationDTO {
  @ApiProperty({
    minimum: 1,
    default: 1,
  })
  @IsNumber()
  @IsOptional()
  @IsInt()
  @Min(1)
  @Type(() => Number)
  readonly page?:number = 1;

  @ApiProperty({
    minimum: 1,
    maximum: 250,
    default: 50,
  })
  @IsNumber()
  @IsOptional()
  @IsInt()
  @Min(1)
  @Max(250)
  @Type(() => Number)
  readonly limit?:number = 50;

  get skip(): number {
    return (this.page - 1) * this.limit;
  }

  get take(): number {
    return this.limit;
  }
}

but when i type queryPageDto.skip (or take) also if is suggested they always returns undefined i tried that whitout IntersectionType and obviously works.

Looks like your issue is that the IntersectionType removes the getters that you have set, which I believe is the expected behavior, right @kamilmysliwiec?

[kamilmysliwiec]

That's correct @jmcdo29
