in our application we are calling a subdialog from a vxml servlet, we can successfully pass in IN parameters and we can log out the OUT parameters but we dont know how to store the OUT parameter data to a DD variable so i can use it later in the application.

here is my vxml servel code:

      out.println("<var name=\"Arg2\"/>");
      out.println("<var name=\"Arg3\"/>");
      
      out.println("<var name=\"VOAppURL\" expr=\"'http://192.168.254.189/SIC/ScriptPlayer.jsp?scriptId=9'\"/>");
      out.println("<var name=\"subprog\" expr=\"'false'\"/>");
      out.println("<var name=\"returnScript\" expr=\"'returnScript=alexbuckhurst'\"/>");
   
      out.println("<subdialog method=\"get\" name=\"VOAppSub\" namelist=\" subprog returnScript\" srcexpr=\"VOAppURL\">");

      out.println("<filled>");
      out.println("<assign expr=\"VOAppSub.returnParam1\" name=\"Arg2\"/>");
      out.println("<assign expr=\"VOAppSub.returnParam2\" name=\"Arg3\"/>");
      out.println("<log>LOG OUT TO AVP Reports:- param 1; <value expr=\"VOAppSub.returnParam1\"/> - param 2; <value expr=\"VOAppSub.returnParam2\"/></log>");
      out.println("</filled>");

      out.println("</subdialog>");



can you please let me know what i need to do to achieve this, thank you

public void markupLanguageGeneration(PrintStream out, Submit submit, SCESession mySession) {


Use the submit to add Arg2 and Arg3 to the submit list.


   submit.addToSubmitList("Arg2");

The the value of VOAppSub.returnParam1 will be submitted to the application server as Arg2. This assumes you have a variable Named "Arg2" in your DD app.

Thats great.

Thanks

I'm having a very similar problem not being able to get any data from a vxml servlet back into OD. I have a complex variable "res" that contains fields (data & action). The Java code is below. Any ideas why it doesn't work?

out.println("<subdialog name=\"res\" src=\"" + vxmlURL + "\" namelist=\"LINE ANI DNIS CALLID\">");
out.println("<param name=\"LINE\" expr=\"'" + pLINE + "'\"/>");
out.println("<param name=\"ANI\" expr=\"'" + pANI + "'\"/>");
out.println("<param name=\"DNIS\" expr=\"'" + pDNIS + "'\"/>");
out.println("<param name=\"CALLID\" expr=\"'" + pCALLID + "'\"/>");   
      
out.println("<filled>");
out.println("<var name=\"res___action\" expr=\"res.action\"/>");
out.println("<var name=\"res___data\" expr=\"res.data\"/>");
out.println("</filled>");
out.println("</subdialog>");

submit.addToSubmitList("res___action res___data");

}

have you declared the variables?

eg out.println("<var name=\"Arg2\"/>");
out.println("<var name=\"Arg3\"/>");

Only in the <filled> element although I've have tried defining them at the form level without any luck. It doesn't throw any semantic errors as it stands.

I'd also tried putting just the "res" object in the namelist but this resulted in "Not able to save posted variable" for each sub field.

Daniel,

When you say "does not work". you are positive your module is returning values. Is there any DD trace to go along with this?

Yes. I added some prompts to the end of the <filled> element and these read out the data correctly. The trace.log extract shows the markup followed by a couple of debug messages. The value of res.action is "x" which I set prior to calling the servlet.

I guess I am confused now. It seems that the value is submitted bases on the log?

can you email me a test case?

I probably wasn't very clear. The markup code generated by the servlet plays some output which proves that the values set in the subdialog have been returned. Unfortunately the values don't get back into OD. I'd expect the trace.log to include:

"Storing :res___action to complex: res:action as [runapp]"
"Storing :res___data to complex: res:data as [1234]"

Following the servlet I have a debug block that outputs the values of res:action and res:data from within OD. The value of res:action shows the "x" that was set prior to the servlet. This tells me that the servlet didn't change the value.

looking at this again you variables that you create are out of scope when the submit is processed. They are only in the scope of the filled. In the filled you should be doing an assign and declare the variables at a higher scope. Look at the way OD generated is vxml.

Thanks - that fixed it.
