Raise a BPM 7.6 flag without needing client side components

Hi, this is my first post and I'm a real newbie with regards to BPM.

I've been pointed to some example code that should allow us to effectively invoke a flag, passing in the required parameters etc.  This all goes into a SOAP call and posted to http://metastorm.org/eWorkTransaction.

I am struggling to find any documentation at all with regards to this.

All of the details of the SOAP call look ok as I can confirm this via the tpWebService.asmx.  The issue is that of the content I must supply.  As stated before, there appears to be no documentation on the structure and format of this.

I've used the example code and have played around with it, but all I get is an exception "The Parameter Is Incorrect".

The snipped of code in use is:

tpRequest =""       

ForEach flagParam In flagParams

            tpRequest = tpRequest & "<![CDATA[" & flagParam & "]]>"

Next

tpRequest = tpRequest & ""

Can anyone give me any pointers, as it suprises me that you don't seem to even have to give the associated map id ?

Thanks in advance!
