WAD: How-to get query name and pass to URL

Hi,

The task: In a BI 7.0 web template - get the technical query name and use that to open a URL in the format http://<MYURL>&DOCUMENTATION=<QUERYNAME>. So:

1) User clicks an icon

2) Get technical name of query

3) Open the documentation for that query using a URL

How can this be done? Do I have to use the Custom Extension web item and implement a new class using the interface IF_BICS_CONS_WEBITEM_CUST_EXIT? If so, do you have an example of how this can be done? OR even better is there an easier way to accomplish this?

Thanks in advance,

Jacob
