Calling APIController

[ChrisChen]

Hi,

I am trying to using Angular report with ApiController OWIN server.

below is my ApiController code, the only difference between sample code and mine is the controller inherits from ApiController, not Controller

Code: Select all

    public class BalanceSheetViewerController : ApiController
    {
        private readonly IBalanceSheetLogic logic;
        private readonly ICompInfoLogic compInfoLogic;

        public BalanceSheetViewerController(
            IBalanceSheetLogic logic,
            ICompInfoLogic compInfoLogic
        )
        {
            this.logic = logic;
            this.compInfoLogic = compInfoLogic;
        }

        [System.Web.Http.HttpPost]
        [AllowCrossSiteJson]
        public ActionResult InitViewer()
        {
            var requestParams = StiAngularViewer.GetRequestParams();
            var options = new StiAngularViewerOptions();
            options.Actions.GetReport = "GetReport";
            options.Actions.ViewerEvent = "ViewerEvent";
            options.Appearance.ScrollbarsMode = true;

            return StiAngularViewer.ViewerDataResult(requestParams, options);
        }
        ......
        

everything looks good until running it. when the client angular runs receive the error from

return StiAngularViewer.ViewerDataResult(requestParams, options)

the error is

Object reference not set to an instance of an object.

and below is the call stacks

Code: Select all

   at Stimulsoft.Report.Web.StiCacheHelper.GetObject(String guid)
   at Stimulsoft.Report.Web.StiCacheHelper.GetResource(String guid)
   at Stimulsoft.Report.Web.StiViewerResourcesHelper.GetStyles(StiRequestParams requestParams)
   at Stimulsoft.Report.Angular.StiAngularViewer.ViewerDataResult(StiRequestParams requestParams, StiAngularViewerOptions options)
   at Beyond.API.Controllers.BalanceSheetViewerController.InitViewer() in BalanceSheetViewerController.cs:line 42
   at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.<>c__DisplayClass6_2.<GetExecutor>b__2(Object instance, Object[] methodParameters)
   at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ExecuteAsync(HttpControllerContext controllerContext, IDictionary`2 arguments, CancellationToken cancellationToken)

Could you help with this?
Thanks!

Hello.

Please try options.Server.CacheMode = StiServerCacheMode.StringCache;

[ChrisChen]

Hello.

Please try options.Server.CacheMode = StiServerCacheMode.StringCache;

Hi, it's still got the null reference error.

Thanks
