Thanks Patrick. I don't know what I'm looking at yet there, but I
have both Howard's and Kent's books, so I know what to look FOR...
This actually doesn't do what you want. This takes a list of elements
(the source) and prints each one in a separate cell in a single long
row.
You wanted a way to introduce new rows each n elements. You'd do that
like this in your .html file:
<table>
<tr>
<span jwcid="@Foreach" source="ognl:list" value="ognl:currentValue"
index="ognl:i">
<span jwcid="@Conditional" condition="ognl:i + 1 % n == 0">
</tr><tr>
</span>
<td>
<span jwcid="@Insert" value="ognl:currentValue.displayValue" />
</td>
</tr>
</span>
In your .page file, you need:
<property-specification name="list" type="java.util.List" />
<property-specification name="currentValue"
type="your.package.ClassName" />
<property-specification name="i" type="int" />
So, what this does is creates a table and a row and loops over each
of the values in the list, setting currentValue to each one in turn
and updating the index variable i.
The @Conditional checks to see if i + 1 % n (you should stick in some
real number there or have another property for n) is 0, and ends the
current row and starts a new one if that's the case. (I think this is
buggy. You may get a blank row at the end.)
The @Insert replaces itself with the output of the getDisplayValue()
method of the currentValue object which is, by virtue of the two
tags, the contents of a table cell.
Given all of that, it may be easier to use the ContribTable
component, where you can specify the size of the table and which
element should go where, but it's do-able.
