Error on EPCMPROXY is undefined

Hi,

I encountered an error message 'EPCMPROXY is undefined' when I have two BSP applications on the same page subscribing to the MSS teamviewer. This problem happens intermittently when I try to change the employee in the MSS teamviewer, to display detailed infomation in the two BSP applications.

In the two BSP applications, I use the following codes to subscribe to the MSS teamviewer upon change of the selected employee. I have tried to use two different procedure name for EPCMPROXY and myreceiveEvent. But the problem still exists. Anyone provide some help on this?

...

<SCRIPT src="epcfproxy.js"></SCRIPT>

<script language=javascript>

var lnDotPos = document.domain.indexOf( "." );

if (lnDotPos >= 0) document.domain = document.domain.substr( lnDotPos + 1 );

EPCMPROXY2.subscribeEvent( 'urn:com.sap.pct.hcm.orgmanagement:CurrentObject', 'objectChanged', window, 'myreceiveEvent2' );

function myreceiveEvent2( eventObj2 )

{

var dataKey2=eventObj2.dataObject;

Emp2.EmpID.value = dataKey2.substr(6,8);

Emp2.submit();

}

</script>
