Hi Peter
I've been struggling with this alternating row thing for the last couple of
days and finally
cracked it this morning. Here is what I have:
[[Test.html]]
<table width="100%" cellspacing="0" cellpadding="3">
<tr valign="top">
<td class="labels"><span key="action">Action</span></td>
<td class="labels"><span key="name">Name</span></td>
<td class="labels"><span key="phone">Phone</span></td>
<td class="labels"><span key="mobile">Mobile</span></td>
<td class="labels"><span key="address">Address</span></td>
<td class="labels"><span key="notes">Notes</span></td>
</tr>
<span jwcid="@Foreach" source="ognl:clients" value="ognl:client"
index="ognl:rowIndex" element="tr" class="ognl:rowStyle">
<td><span jwcid="@Insert" value="ognl:rowIndex + 1">1</span></td>
<td><span jwcid="@Insert" value="ognl:client.name">George
Smith</span></td>
<td><span jwcid="@Insert" value="ognl:client.phone">5555
1234</span></td>
<td><span jwcid="@Insert"
value="ognl:client.mobile">0400100200</span></td>
<td><span jwcid="@Insert" value="ognl:client.address">3 Claire
Way</span></td>
<td><span jwcid="@Insert" value="ognl:client.notes">No notes</span></td>
</span>
<tr valign="top">
<td class="trailer" colspan="10">End of list</td>
</tr>
</table>
[[Test.java]]
private int rowIndex = 1;
public void setRowIndex(int rowIndex) {
this.rowIndex = rowIndex;
}
public int getRowIndex() {
return rowIndex;
}
public String getRowStyle() {
if (rowIndex%2 == 0)
return "even";
return "odd";
}
[[Application.css]]
.even {
background-color: #f0f0f0;
}
.odd {
background-color: #a0a0a0;
}
And I'm not going to say HTH as I know it will.
Cheers

PS I'm sure there is another way to do this using a bean but the above does
make sense in
Tapestry and you not only get the even/odd thing, you also get a row counter.
PPS The other bit I did was to move the content of the getRowStyle() method to
an
application class, I'm going to use this on lots of pages and if I change the
names of the
even/odd styles I want to do this in one place and not 50. So it became:
public String getRowStyle() {
return SomeApplicationClass.getRowStyle(rowIndex);
}
