Cannot assign an object to a variant array in a Web Service Request

Question

Hello,&nbsp;I have a Web Service which has a similar structure:&nbsp;&lt;Body&gt;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&lt;WebMethod1&gt;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;VariantOfObject1&gt;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;Object1&gt;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&lt;node1/&gt;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&lt;node2/&gt;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&lt;node3/&gt;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;/Object1&gt;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;Object2&gt;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&lt;node1/&gt;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&lt;node2/&gt;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&lt;node3/&gt;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;/Object2&gt;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;/ArrayOfObject1&gt;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&lt;/WebMethod1&gt;&lt;/Body&gt;&nbsp;And in order to assign an object to each Array entry, I use the following code:&nbsp;function RequestObject (){&nbsp;var TypeFactory;var Result;&nbsp;TypeFactory = WebService.MyWS.TypeFactory;Result = TypeFactory.ArrayOfObject;Result.Object = BuiltIn.CreateVariantArray(0,1);&nbsp;for (var i=0; i&lt;2;i++){Result.Object(i) = TypeFactory.Object;Result.Object(i).node1 = "a";Result.Object(i).node2 = "a"Result.Object(i).node3 = "a"}return Result;}&nbsp;With this code, the object generates just fine, but when I try to assign the generated object to an entry of the Array, I see that the array doesnt save the object in each entry and appears as a "undefined" value and and the data type is "String", instead of "(Object)". Can you guys help me out with this please? I have looked everywhere and I dont seem to find the answer nor I can find a work around. If you need extra information, I will gladly give it.

Hi,
&nbsp;
a) Objects cannot be transferred by Web Services, but only their serializations (which are usually strings);
b) Result.Object = BuiltIn.CreateVariantArray(0,1);
this creates an array with two elements (with indexes 0 and 2) but in the cycle
for (var i=0; i&lt;2;i++)
you are trying to address three elements. (BuiltIn.VarArrayLowBound() and BuiltIn.VarArrayHighBound() are recommended to avoid such mistakes);
c) Are you using the code generated by TestComplete or crafted by yourself?
&nbsp;
If you can send me (through this thread or privately) the contents of the WebServices folder of your project I will try to help you with the code.

Hi Alex,&nbsp;Thank you for your answer, now I used the code generated by test complete with the "Code" button and got the following:&nbsp;function ArrayOfProgrammeMemberActivity(){var Result;var TypeFactory;//Get the type factory for the web serviceTypeFactory = WebServices.MemberWebService.TypeFactory;Result = TypeFactory.ArrayOfProgrammeMemberActivity;//Generating the array property. Choose the lower and upper array bounds that meet your needsResult.ProgrammeMemberActivity = BuiltIn.CreateVariantArray(0, 10);var i;for(i = BuiltIn.VarArrayLowBound(Result.ProgrammeMemberActivity, 1); i &lt;= BuiltIn.VarArrayHighBound(Result.ProgrammeMemberActivity, 1); i++){Result.ProgrammeMemberActivity(i) = TypeFactory.ProgrammeMemberActivity;Result.ProgrammeMemberActivity(i).PmaType = "";Result.ProgrammeMemberActivity(i).Merged = "";Result.ProgrammeMemberActivity(i).Cancelled = "";Result.ProgrammeMemberActivity(i).RecordLocator = "";}return Result;}&nbsp;This was generated by test complete but I still get an array with "undefined" entries, the example I posted at the begging was an example based on this code, sorry if I didnt post it to begin with. I hope this helps you out more Alex in uderstanding the issue. I attach an image of what test complete gives me as a result when I run this code.

Any suggestions of what might be happening? or what am I missing?

Hi,
&nbsp;
As I said, it's not easy to provide you with the actual code without having either the service wsdl file or the contents of the WebServices subfolder of TestComplete project, but the general approach is:
-- you create the request. This gives you the request object and its parameters (first level);
-- if some of the first-level parameters are complex ones, then you must create and initialize their structure and assign the structure to the parameter.
&nbsp;
You might consider the sample from the &lt;Users&gt;\Public\Documents\TestComplete 11 Smaples\Common\Web Service Testing folder and adopt it to your case .

Hi Alex,&nbsp;I tried many options and still can't get it to work. I could provide the WSDL URL we use, where can I share with you?
