[Twisted-web] How to fill slots in sub-pattern

[Paul Reznicek]

Hi all,

I've one page template and would like to use different pattern in different
Page subclasses.
A snipped of the template:

# ----------------------------------------------
             <td class="main">
                 <n:invisible n:render="contentMain" n:data="contentData">
                 <table n:pattern="contentTable" n:render="sequence">
                     <tr n:pattern="header">
                         <th id="firstHeader">First Column</th>
                         <th id="secondHeader">Second Column</th></tr>
                     <tr n:pattern="item" n:render="row">
                         <td><n:slot name="first_column" />data1</td>
                         <td><n:slot name="second_column" />data2</td>
                     </tr>
                 </table>

                 <table n:pattern="otherTableData" n:render="sequence">
                     <tr n:pattern="header">
                         <th id="firstHeader">Col 1</th>
                         <th id="secondHeader">Col 2</th></tr>
                         <th id="thirdHeader">Col 3</th></tr>
                     <tr n:pattern="item" n:render="row">
                         <td><n:slot name="first_column" />data1</td>
                         <td><n:slot name="second_column" />data2</td>
                         <td><n:slot name="third_column" />data3</td>
                     </tr>
                 </table>
                 </n:invisible>
             </td>
# ----------------------------------------------

The renderer should work like this:
# ----------------------------------------------
     def render_contentMain(self, ctx, data):
         patternHere = inevow.IQ(ctx).onePattern('contentTable')
         patternHere.fillSlots('first_column', data[0])
         patternHere.fillSlots('second_column', data[1])
         return patternHere.tag
# ----------------------------------------------

But this does not work ...
Can somebody help me?

Thanks in advance,
Paul
