Hey,
By returning "this" in the onSuccess event, a redirect happens resulting
in a new request. If you want to preserve data between requests, you
will have to save it into the http session.
If you add http session persistence, the data will be available after a
new request. <http://tapestry.apache.org/persistent-page-data.html>
Simple example for your case:
@Persist
@Property
private Set<Street> streets;||
Be careful: in this case the whole streets set is saved into the http
session and will remain there until the end of the session (or until you
remove it manually).
You could also persist the form vaues instead and then in setupRender
event fill the trees set based on these values.
Also you can make use of PersistenceConstants.FLASH to let Tapestry
remove it from the session after first access automatically.
See more info: http://tapestry.apache.org/persistent-page-data.html||
Another option is making use of AJAX where the updated grid html is sent
back in the response and updated on the client side. If you want to
achieve this you'll need to add a Zone around the grid and make your
Form submit with AJAX.
Your case:
<t:form t:zone="zoneGrid">
...
<t:zone t:id="zoneGrid" id="zoneGrid"
<t:grid source="streets" row="street">
</t:grid>
</t:zone>
<t:form>
@Inject
private AjaxResponseRenderer ajax;
@InjectComponent
private Zone zoneGrid;
void onSuccess() {
...
ajax.addRender(zoneGrid);
}
See more info: http://tapestry.apache.org/ajax-and-zones.html
Hope this helps u a bit.

Hi,
I'm trying to make a make grid update when submitting a form within the
same page.
Here is the code:

The page gets refreshed but the table/source doesn't seem to be updated.
Any help is greatly appreciated.
