Re: 2nd try: ajax updating components inside a For
After the update from Jesse, the test-page I mentioned in a previous
thread behaves as expected. Thank you for the fix.
If anyone is interested the test page java+html is as follows:
package dk.atira.commonstest.pages;
import org.apache.tapestry.IRequestCycle;
import org.apache.tapestry.annotations.Persist;
import org.apache.tapestry.event.PageBeginRenderListener;
import org.apache.tapestry.event.PageEvent;
import org.apache.tapestry.html.BasePage;
public abstract class NumericPage extends BasePage implements
PageBeginRenderListener {
@Persist
public abstract String[] getRows();
public abstract void setRows(String[] rows);
public abstract String getRow();
public abstract int getTheIndex();
public void pageBeginRender(PageEvent e)
{
if (getRows() == null){
setRows(new String[] {"foo", "bar", "baz"});
}
}
public void aListener(IRequestCycle cycle, int idx)
{
getRows()[idx] = "" + (int)(Math.random()*1);
}
}
index="ognl:theIndex">
Update "value="ognl:components.therow.clientId"> "

Thanx jesse, thats great !
I guess I miss some basic understanding of how for works in ajax
context, but I still didn't manager to update a single iteration -
Currently it only works if you update the container of the for, and
still there are some issues with multiple posts (I added a jira issue).
Would you/? explain what would be the preferred way to solve this prob
(updating a form inside a single iteration)?
Cheers,
Ron

Hi all,
I have a simple For loop which iterates over some object.
the objects are all rendered to DirectLinks.
When a DirectLink-listener is called, the clicked Item should change to
"edit view" and render a Form instead of the Link.
When the form is submitted, the item should render again to the Link (
"view mode").
Now the question is, how to change the code below, to do the trick with
ajax.
When using normal http requests the page looks like this:
try ajax with list
listener="listener:doCancel"/>
value="ognl:currentObject.name">
and the class:
public abstract class Home extends BasePage
{
public Object getObjects() {
// return the list of obejcts
}
/** the value of the current iteration */
public abstract Value getCurrentObject();
@Persist
public abstract Value getEditObject();
public abstract void setEditObject( Value v );
public boolean isEditMode() {
return getEditObject() != null &&
getEditObject().equals( getCurrentObject() );
}
public void edit( Long id ) {
setEditObject( getObject( id ) );
}
public void doSubmit() {
// ... save ... and then
this.setEditObject ( null );
}
public void doCancel() {
this.setEditObject( null );
}
private Value getObject( Long id ) {
// ... return the value for the given id
}
}
Thanx in advance,
