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
