Hi, I try to learn Web-programming by TWebCore. In past I design vcl, only. I have a connection to the MySQL-Server and can get the data from an easy query.Server-Connection: TFDConnection TAureliusConnection TFDPhysMySQLDriverLink WebCore Project TXDataWebDataSet When I understand it r…

I tried it and I read the documentation, but I am not able to solve it, sorry! When I check the Response.ResponseText I can see, that the data are in. When I try "XDS_Abteilung.SetJsonData(TJSArray(Response.Result));" nothing happens. I wanted to check an fieldvalue by: XDS_Abteilung.Active:=true;X…

For a better understanding the whole procedure with the service all and the OnResponse procedure... procedure TFrmMain.btnAbteilungClick(Sender: TObject); procedure OnResponse(Response: TXDataClientResponse); begin showmessage(Response.ResponseText); XDS_Abteilung.SetJsonData(TJSArray…

The content of Response.Result: {"FDBS":{"Version":15,"Manager":{"UpdatesRegistry":true,"TableList":[{"class":"Table","Name":"Query_Main","SourceName":"abteilung","SourceID":1,"TabID":0,"EnforceConstraints":false,"MinimumCapacity":50,"ColumnList":[{"class":"Column","Name":"AbteilungsID","SourceName"…

Do I have to define the fields? I tried it manually without a EntitySetValue. Afterwards I got a new error-message: ERROR Uncaught TypeError: Cannot read property 'FAttributes' of null | TypeError: Cannot read property 'FAttributes' of null at Object.LoadData ( http://localhost:8000/Web_App/Web_App.…

I tried it on this way:XDS_Abteilung.Close;XDS_Abteilung.SetJsonData(TJSArray(TJSObject(Response.Result)['FDBS.Manager.TableList.RowList']));XDS_Abteilung.Open; But I get the error-message: Cannot read property 'FDBS.Manager.TableList.RowList' of null at OnResponse That is the formated JSON-Stream:{…

Your JSON contain several structures, this is how you should access the array (you can simplify this code of course using a single line, I have created several variables for better understanding: var JFDBS: TJSObject; JManager: TJSObject; JTableList: TJSObject; JRowList: TJSArray; .. J…

Hi Wagner, thanks for support! I defined the fields and changed my procedure like you descripted: procedure TFrmMain.btnAbteilungClick(Sender: TObject); procedure OnResponse(Response: TXDataClientResponse); var JFDBS: TJSObject; JManager: TJSObject; JTableList: TJSObject; …

I checked the function via swagger. May be the following message helps to understand what is happen: "Unrecognized response type; displaying content as text." The function is defined:function TData_xChangeService.Get_Abteilung: TStream;var LResult: TMemoryStream; SQL_String: string;begin LR…

First you need to make sure your server is returning correct data. Open your browser console and check the network tab to see what the server is returning when you are invoking the IData_xChangeService.Get_Abteilung method. This way we can focus either on client or server.

when I call the funtion ( http://localhost:8000/tms/xdata/Data_xChangeService/Get_Abteilung ) in the browser, taht is the result:// 20191105151638// http://localhost:8000/tms/xdata/Data_xChangeService/Get_Abteilung { "FDBS": { "Version": 15, "Manager": { "UpdatesRegistry": true, "Tabl…
