Invoking a subdialogue and passing HTTP parameters

This example shows how to invoke a VoiceXML subdialogue which requires HTTP parameters.

We proceed as with Invoking a subdialogue but we define a VariableList that will contain the various parameters. Be careful as initial value for each parameter is a JavaScript expression, so don't forget relevant quoting:

Dialogue.java:

VariableList parameters = new VariableList();
parameters.addWithExpression("parameter1", "'value1'");
parameters.addWithExpression("parameter2", "'value2'");

We set those parameters in the turn as submit parameters:

Dialogue.java:

subdialogueCall.setSubmitParameters(parameters);
