Hi everyone,
I have been tried to get Tapestry to display radio buttons in two columns
like below. The radio buttons are dynamically generated from a collection.
Naturally, I tried using a ForEach component looping through the collection.
At first, I tried having the ForEach component step through 2 at a time but
that didn't work. Unless I am wrong, ForEach does not have an "increment by
n" option. Finally, I tried simply checking whether it is the first or
second radio button. If it is the first one, then I put in the <tr> tag.
If it is the second, I put in the </tr> tag. The problem is I cannot seem
to get Tapestry to take it. Apparently, you cannot just stick a closing tag
</tr> within a <span> tag without the <tr> tag.
That's true...
But, you can do a simple hack.
In the first conditional span, include
<span jwcid="@Insert" raw="true" value="ognl:trOpen"/>
, in the second
<span jwcid="@Insert" raw="true" value="ognl:trClose"/>
and in the java source add
public String getTrOpen() { return "<tr>";}
public String getTrClose() { return "</tr>";}
It's a bit ugly, I know, but it works...
My non-working code is as
follows:
<table>
<form jwcid="@Form">
<span jwcid="@RadioGroup" selected="selectedRejectedReasonCode">
<span jwcid="@Foreach" source="rejectedReasons"
value="rejectedReason">
<span jwcid="@Conditional"
condition="ognl:isOddRejectedReasonIndex()">
<tr>
</span>
<td>
<input type="radio" jwcid="rejectedReasonRadio"/><span
jwcid="rejectedReasonRadioDescription"> Previously Approved</span><br/>
</td>
<span jwcid="@Conditional"
condition="ognl:isOddRejectedReasonIndex()">
</tr>
</span>
</span>
</span>
</form>
</table>
Anybody has a better recommendation as to how to do something like this. I
am sure most of you have done this a million times before, but for the life
of me, I cannot figure it out.
Thanks,
Ben Wong
