C# SAP GUI Automation: DoubleClickNode Generates Runtime Error

Question

I'm using C# in order to automate SAP GUI 7.40 with sapfewse.ocx (inspired By How do I automate SAP GUI with c#)

I'stuck with an error on runtime when the script have to double click on leef of a tree.

private GuiApplication sapEngine { get; set; }
private GuiConnection sapConnexion { get; set; }
private GuiSession sapSession { get; set; }

sapEngine = new GuiApplication();
sapConnexion = sapEngine.OpenConnection(sapGUIConfig.EndPoint,Sync:true);
sapSession = (GuiSession)sapConnexion.Sessions.Item(0);

// ...

    GuiTree treeFilters = getTreePath("wnd[0]/usr/ssub%_SUBSCREEN_%_SUB%_CONTAINER:SAPLSSEL:2001/ssubSUBSCREEN_CONTAINER2:SAPLSSEL:2000/cntlSUB_CONTAINER/shellcont/shellcont/shell/shellcont[1]/shell");
                    treeFilters.ExpandNode("          1");
                    treeFilters.SelectNode("         16");
                    treeFilters.TopNode = "         15";
                    treeFilters.DoubleClickNode("         16");
    
                    // Crash Here after DoubleClickNode Method
    

SAP ERROR: "The SAP application had to terminate due to an ABAP runtime error."

Note :

The same automation script manage with sapRotWrapper (SapROTWr.CSapROTWrapper) works

sapROTWrapper = new SapROTWr.CSapROTWrapper();
sapGUIROT = _sapROTWrapper.GetROTEntry("SAPGUI");
//Get the reference to the Scripting Engine
sapEngine = sapGUIROT.GetType().InvokeMember("GetScriptingEngine", System.Reflection.BindingFlags.InvokeMethod, null, sapGUIROT, null);

sapConnexion = sapEngine.OpenConnection(sapGUIConfig.EndPoint);
sapSession = sapConnexion.Children(0);

// ...

sapSession.FindById("wnd[0]/usr/ssub%_SUBSCREEN_%_SUB%_CONTAINER:SAPLSSEL:2001/ssubSUBSCREEN_CONTAINER2:SAPLSSEL:2000/cntlSUB_CONTAINER/shellcont/shellcont/shell/shellcont[1]/shell").expandNode("          1");
                sapSession.FindById("wnd[0]/usr/ssub%_SUBSCREEN_%_SUB%_CONTAINER:SAPLSSEL:2001/ssubSUBSCREEN_CONTAINER2:SAPLSSEL:2000/cntlSUB_CONTAINER/shellcont/shellcont/shell/shellcont[1]/shell").selectNode("         16");
                sapSession.FindById("wnd[0]/usr/ssub%_SUBSCREEN_%_SUB%_CONTAINER:SAPLSSEL:2001/ssubSUBSCREEN_CONTAINER2:SAPLSSEL:2000/cntlSUB_CONTAINER/shellcont/shellcont/shell/shellcont[1]/shell").topNode = "         15";
                sapSession.FindById("wnd[0]/usr/ssub%_SUBSCREEN_%_SUB%_CONTAINER:SAPLSSEL:2001/ssubSUBSCREEN_CONTAINER2:SAPLSSEL:2000/cntlSUB_CONTAINER/shellcont/shellcont/shell/shellcont[1]/shell").doubleClickNode("         16");

Is there somebody can help me ?

Note : I've the same graphical troubles on screen during the execution, all components are not well displayed, There's a link ? (like in the question How to Automate SAP GUI 750 with C#)

Answer 1

Since my previous post, after a long time of experimenting unprobably solutions, I've find the way to solve this problem.

It will be resume of a mix of the different set of code i've mentionned.

The objects used to manage the connection and session must be written with sapRotWrapper (

using SAPFEWSELib;
//...
sapROTWrapper = new SapROTWr.CSapROTWrapper();
sapGUIROT = _sapROTWrapper.GetROTEntry("SAPGUI");
//Get the reference to the Scripting Engine
sapEngine = sapGUIROT.GetType().InvokeMember("GetScriptingEngine", System.Reflection.BindingFlags.InvokeMethod, null, sapGUIROT, null);

sapConnexion = sapEngine.OpenConnection(sapGUIConfig.EndPoint);
sapSession = sapConnexion.Children(0);

But The access to tree must done with the GuiTree object

GuiTree treeFilters = getTreePath("wnd[0]/usr/ssub%_SUBSCREEN_%_SUB%_CONTAINER:SAPLSSEL:2001/ssubSUBSCREEN_CONTAINER2:SAPLSSEL:2000/cntlSUB_CONTAINER/shellcont/shellcont/shell/shellcont[1]/shell");
                treeFilters.ExpandNode("          1");
                treeFilters.SelectNode("         16");
                treeFilters.TopNode = "         15";
                treeFilters.DoubleClickNode("         16");
