Workflow PostEvent method not working

[hamidouikene]

Expected Behaviour

PostEvent from xtk:workflow to send an event to a signal in a workflow

Actual Behaviour

The SDK throws an error because it's expecting the parameters to be inside a variables entity.

Reproduce Scenario (including but not limited to)

Just use the SDK and call PostEvent method: await NLWS.xtkWorkflow.postEvent(name, 'signal', '', variables, false);

Steps to Reproduce

Platform and Version

Sample Code that illustrates the problem

The SDK throws an error when I try to use PostEvent from xtk:workflow schema. The error says that Parameters must be inside a 'variables' entity (instead of 'parameters'). I took a look at the code and it looks like the XML element name is overriden for method StartWithParameters only.

// Hack for workflow API. The C++ code checks that the name of the XML element is <variables>. When
// using xml representation at the SDK level, it's ok since the SDK caller will set that. But this does
// not work when using "BadgerFish" representation where we do not know the root element name.
if (entitySchemaId == "xtk:workflow" && methodName == "StartWithParameters" && paramName == "parameters")
    docName = "variables";

Is there a reason this hack is not implemented for the other methods? PostEvent for example?

Hi @hamidouikene, thanks for the detailed report. Indeed, this is missing. There's no particular reason for this hack not being in PostEvent, it's just a miss. I'll publish a fix ASAP.

[mkiki]

This should be fixed in build 1.1.47 The following methods will be fixed: StartWithParameters, PostEvent, SimulateWithParameters, SpawnWithParameters, and SpawnWithParametersEx

Thank you so much @mkiki!

@mkiki I can close this one if you want.
