contrib:Table, JavaScript, and DirectLinks
Tapestry users,
I am writing a Tapestry app with a summary/detail set of screens.
Clicking anywhere in a summary row (generated by contrib:Table
components) allows the user to drill down to the detail screen.
I have a _gross_ hack for this involving JavaScript and a DirectLink
component.
Here is my current solution:
<GROSS HACK>
--- In .page specification ----------------------
<component id="detailLink" type="DirectLink">
<binding name="listener" expression="listeners.DetailListener"
/></component>
--- Method (called from ognl) defined in .java page class ---
public String getDetailActionScript()
{
TableRows rows = (TableRows)getComponent("rows");
SplashMessage currentRow = (SplashMessage)rows.getTableRow();
DirectLink link = (DirectLink)getComponent("detailLink");
// set properties attribute of DirectLink so our listener can
// pick up an id in the parameter array
try {
BeanUtils.setProperty(link, "parameters",
currentRow.getId());
} catch (Exception ignore) {}
String url = link.getLink(getRequestCycle()).getURL();
return "go('" + url + "')";
}
--- In .html template ---------------------------
<script
...
function go(url) {
window.location=url;
}
</script>
...
<tr jwcid="rows@contrib:TableRows"
class="ognl:beans.evenOdd.next"
onclick="ognl:detailActionScript"
onmouseover="rowMouseOver(this)"
onmouseout="rowMouseOut(this)">
...
</tr>
</table>
<!-- To get rid of warning that component wasn't used -->
<span jwcid="detailLink" />
</GROSS HACK>
Dumping a DirectLink component into my page like this smells bad.
The code in getDetailActionScript() is also nearly un-maintainable.
Does anyone have ideas to make this all more Tapestry-like?
Thanks to all for reading,
Paul-Michael Bauer

I recently tried to do something similar. Being a tapestry newbie it
took some mucking about until I gor it to work. Anyways I've attached a
HTML-file where I jotted down how I did it. Hopefully it can give some
ideas or at least something for you veterans to laugh at :-)
Elementary question: How does component pass reference to itself when invoking IActionListener
Posted by kranga <kr...@k2d2.org>.
The actionTriggered takes a reference to the calling component, but there
doesn't seem to be any method on the request cycle that eventually makes its
way to the listener to find out who called to get a reference to the calling
component.
I know I can use the set/get Attribute() method and pass a reference, but
thats a kludge at best. What am I missing?

Did you try e-mailing Manning and see if they'll give you a discount?

good place to order many copies of Howard's book
Posted by Andrew Arrow <an...@verizon.net>.
Is there a good place to order many copies of Howard's book? My company is
thinking about getting 20 copies or so for a class on Tapestry. We were just
going to order from best price here:
http://www.shopzilla.com/12--Tapestry_in_Action_-_cat_id--8096__prod_id--11326315
unless there is a sneaky Tapestry-User-Mailing-List-Place to order from?
Thanks,
-Andrew

Re: contrib:Table, JavaScript, and DirectLinks
Posted by Derek Brown <ze...@yahoo.com>.
Hello,
I have taken the same approach. But my question is how
do I get a Integer parameter set. When i do something
like obj.getId() - This usally returns a
java.lang.Integer, but this shows up as a service
parameter sp=S(id). So now I have to use instance of
in the action to watch for both strings or integers.
How can I make sure it gets set as an Integer and not
a String?
Thanks
