Hi Jeremy,
You're using the wrong method, use getInput, not getParameter.
Parameters are part of submissions.
You can also create a setTableId method in your element, and RIFE
will automatically inject the value.
HTH,

Hi All,
I have an application where I want to have an element called
DatabaseBrowser. This element will display all tables of a given
database. Each displayed table will be a link to the
DatabaseBrowser with a parameter called tableId. Here is how it
will work:
If the tableId is not present, display all tables. If the tableId
is present, display the table-specific information.
My problem comes in my site definition. I'm not sure how to pass
the data properly. Everything I've done thusfar has resulted in:
com.uwyn.rife.engine.exceptions.ParameterUnknownException: The
element 'manual:AdminDatabaseBrowser' doesn't contain parameter
'tableId' in any submission.

Here is the important portion of the site definition:
<element id="AdminDatabaseBrowser"
implementation="net.collab.extranet.sac.elements.AdminDatabaseBrowser"
url="/admin/databasebrowser">
<input name="tableId" />
<output name="tableId" />
<flowlink srcexit="AdminDatabaseBrowser"
destid="AdminDatabaseBrowser" />
<datalink srcoutput="tableId" destid="AdminDatabaseBrowser"
destinput="tableId" />
</element>
My concern is that this isn't a typical way to pass data. I've
looked through the examples and I cannot find anything specific to
what I need. I will continue looking but if anyone can help me
figure out where I'm going wrong, I would appreciate it.
Take care,
Jeremy
