doAction returns null using getGadgetInfo and getGadgetData in pega 7.3. What am I missing?
I have tried the functions in the following ways and all return null:
- var gadgetInfo = pega.web.api.doAction("PegaGadget", "getGadgetInfo")
- var gadgetData = pega.web.api.doAction("PegaGadget", "getGadgetData", ".pyID")
- var gadgetData = pega.web.api.doAction("PegaGadget", "getGadgetData", "[gadget/PegaGadget/.pyID]")
- var gadgetData = pega.web.api.doAction("PegaGadget", "getGadgetData", "pyWorkPage.pyID")
After tracing both with web inspector, I was able to get the information from getGadgetInfo if I change the pega.web.isWebMashup to false. But that didn't work with getGadgetData.
The function _doApiAction path uses 'postActionToGadget' instead of '_getGadgetInfo()':
if (pega.web.isWebMashup == true && this._isGadgetAction(A)) {
this._postActionToGadget(B);
return
}
...
case "getgadgetinfo":
return this._getGadgetInfo();
case "getgadgetdata":
return this._getGadgetData(B[2]);
Post action takes it to:
pega.Mashup.Communicator.send(D, B) sends information what seems to be a JSON object:
{payload: X, uid: V, src: W, target: U.target}
X = {gadgetName: "PegaGadget", name: "getGadgetInfo"}
V = "HostPage108"
W = "HostPage"
U = {target: "PegaGadgetIfr"}

U = {target: "PegaGadgetIfr"}
But there is no return of data or variable.
What am I missing?
I generated the code with pega 7.3 virtual machine from course 'Customizing the User Experience':

Thank you!

You are doing nothing wrong. In 7.2.1 we changed to window.postMessage for getting data from the PRPC content. This required us to use a callback function. I have already asked that the Mashup documentation get updated and from what I know it should be done soon. There is even an SA article I wrote thats pending a publish.
Anyway. Here is a sample solution for you trying to get pyFirstName from page OperatorID:
function getTheGadgetData(){
pega.web.api.doAction("PegaGadget", "getGadgetData", "OperatorID.pyFirstName", {callback: callBackForOperatorName});
}
function callBackForOperatorName (rtnValue)
{
alert("Current Operator First Name: " + rtnValue);
}
The proper syntax for the property is "<PageName>.<ProperyName>"
In PRPC you do not use Data Fields starting in 7.2.1. Instead you drag a text control and change the control to use "Hidden Input".

Thank you for your answer ChrisKoyl,
I did a quick test adding a hidden input and the callback but it didn't work. I haven't had time to test well, I'll post after I double check your answer.
Please let me know when you publish the SA article.

I have tried it but it did not work either.Did I miss something?
Code:
function GetID(){
pega.web.api.doAction("PegaGadget", "getGadgetData", "pyWorkPage.ID",{"callback":AAA});
}
function AAA(rtnValue)
{alert("Current Operator First Name: " + rtnValue);
}
