Try this out


function openActivity()
var oSafeURL = new SafeURL("Ecorp-Report.TestActivity");

openUrlInWindow(oSafeURL, 'popup', 'width=850,height=350,left=100,scrollbars=yes,resizable=yes,status=no,toolbar=no,menubar=no');

To call an activity using java script : 


    var bSafeURL= new SafeURL("A-B-C.ActivityName");

    pega.util.Connect.asyncRequest('GET', bSafeURL.toURL(),'');


2) var oSafeURL = new SafeURL("@baseclass.testActivity");

oSafeURL.put("ClassName", insName);
var strRuleXml = httpRequestAsynch( oSafeURL.toURL(), null, 50, 100);


apart from there there lot other ways to do it. 


Some ways that we can achive a  call to activity and open popup window / model window


1) openUrlInWindow(pxReqURI + "?pyActivity=A-B-C.ActivityName&Param1=" + value1, "InteractionData", "status=yes,toolbar=no,menubar=no,location=no,scrollbars=yes,resizable=yes,left=192,top=51.2,height=500,width=800");

pxReqURI = pxRequestor.pxReqURI value



activityURL = "<pega:reference name="pxRequestor.pxReqURI" mode="normal"/>?pyActivity=Work-myActivity&myParameterName=" + valueToPass;
windowOptions = "width:500;height:600;resizable: yes; scroll: yes; help: no";



 var strWindowName = "Popup window title";
 var objSafeUrl = new SafeURL("A-B-C.Activity Name");
 var contentWin = showModalDialog(objSafeUrl.toURL(), strWindowName , "width:500;height:600;resizable: yes; scroll: yes; help: no;");


4)   var objSafeUrl = new SafeURL("A-B-C.Activity Name");

windowOptions = "width:500;height:600;resizable: yes; scroll: yes; help: no";
openUrlInWindow(objSafeUrl .toURL(),"WINDOWNAME",windowOptions,false);

I am using below code to call the activity from javascript. And I want to receive multiple parameters back inside control. I am using show-property inside activity to take one parameter back to control. Is there anything like bSafeURL.put("param3",value3); to recive output parameter in activity back to control?

var bSafeURL= new SafeURL("A-B-C.ActivityName");

you can return mulitple values in show-property Method. you can try like

Param.ReturnValues="Value1 :"+.value1+","+"Value2 :"+.value2




AND use this Param in the show-property . In java script , you can parse CSV.

I am trying to open the work object and render the flow action on click of the url. But I am getting a blank screen. It is because the WO is opening in a different thread which is not popping up on the screen.

Hence, I am calling the below script in the section(Which is embedded in the harness; which is further refered in the portal).


<script type=text/javascript>

window.attachEvent("onload", fnName);

function fnName()

oSafeURL =null;
var oSafeUrl = new SafeURL("ClassName.TestActivity",getReqURI());


The logic in the 'TestActivity' is to do an to do an Obj-Open  by handle and call the activity 'StartNewFlow'.I am still not able to render the flow action.

Can you please advice.


Note: It is poping up hi1 and hi2.

you can try passing teh pzPrimaryPageName paramater to the safe URL. activity do not need any additional paramter. just add this paramter with the primary page name map to it.

var oSafeUrl = new SafeURL("ClassName.TestActivity",getReqURI());



when you setting the primary page value try to get it dynamically using the api methods. for ex:(tools. getPrimaryPage().getName()) or according to the context you are in the methods will vary.

tools.getActive().getPageValue().getName() if this is used in a control which use the StreamBuilderToolKit.

or if called using activity step tools.getStepPage().getName() would do.

Just give it a try this may solve the issue.

Note: i really do not exactly remember the methods name and if those are corret but this will give you some idea to find out. :)
