Re: Manipulate components inside a @For with DirectLink.
The solution looks quite nice. After our experimentations with For, we
realized that the state of each minimize of each TabGroup should be a part
of a List and not in the component. And that's where the TabGroupView fits
in.
Quite an eye-opener!! I always had the impression that a For loop would
render 'n' different components and not just one.

Hi,
Thanks for your reply.
Yes, I found a solution:
I created a new "wrapper"-component who does the for-loop stuff. I
called it TabGroupView. Within this component I can save the
maximize/minimize status of all my TabGroups.
This means I moved my @For loop from the Home.html into this
component. My DirectLink-Listener is now also in the TabGroupView
component so I have full control over all groups.
Some example code:
Home.html:
TabGroupView.html:
TabGroupView.java:
public void linkActionToggleGroup(IRequestCycle cycle) {
Object[] params = cycle.getListenerParameters();
int index = (Integer) params[0];
Map minMap = (Map) params[1];
Boolean oldValue = (Boolean) minMap.get(index);
minMap.put(index, !oldValue);
setMinimizedMap(minMap);
}
public boolean isMinimized() {
if (getMinimizedMap().containsKey(getIndex())) {
return getMinimizedMap().get(getIndex());
} else {
getMinimizedMap().put(getIndex(), false);
return false;
}
}
TabGroup.html:
TabGroup.java:
@Parameter(name="parameters", required=false)
public abstract Object getParameters();
@Parameter(name="listener", required=false)
public abstract IActionListener getListener();
Not sure if this is the preferred way, but it works. :)

Re: Manipulate components inside a @For with DirectLink.

public boolean isMinimized() {
if (getMinimizedMap().containsKey(getIndex())) {
return getMinimizedMap().get(getIndex());

getMinimizedMap().put(getIndex(), false);
return false;

After some discussions and experimentation with a colleague of mine, it
appears that there is only one component. that's the nature of the For
loop. We did this in the listener on the page:
Map comps = this.getComponents();
Set keyMap = comps.keySet();
for (Iterator iter = keyMap.iterator(); iter.hasNext();) {
System.out.println( comps.get(iter.next()));
}
Hence, if a For loop iterates over 'n' elements and writes out a
@Util:TabGroup, there is just one component @Util:TabGroup.
I suppose what it means is that for you to iterate over your list and
control the maximize/minimize stuff, you'll have to have this as an
attribute in the For loop's List, and accordingly use some client side
scripting to handle maximize/minimize.
Unless there is an attribute of the For loop that forces generation of one
@Util:TabGroup for every iteration. If there is some such parameter, I am
not aware of it
Good luck.

Re: Manipulate components inside a @For with DirectLink.
any luck with this issue?
After some discussions and experimentation with a colleague of mine, it
appears that there is only one component. that's the nature of the For
loop. We did this in the listener on the page:
Map comps = this.getComponents();
Set keyMap = comps.keySet();
for (Iterator iter = keyMap.iterator(); iter.hasNext();) {
System.out.println( comps.get(iter.next()));
}
Hence, if a For loop iterates over 'n' elements and writes out a
@Util:TabGroup, there is just one component @Util:TabGroup.
I suppose what it means is that for you to iterate over your list and
control the maximize/minimize stuff, you'll have to have this as an
attribute in the For loop's List, and accordingly use some client side
scripting to handle maximize/minimize.
Unless there is an attribute of the For loop that forces generation of one
@Util:TabGroup for every iteration. If there is some such parameter, I am
not aware of it
Good luck.

Re: Manipulate components inside a @For with DirectLink.
The TabGroup has a @DirectLink to change the state: minimized/maximized.
Home.html:
TabGroup.html:
TabGroup.jwc:
TabGroup.java:
public abstract class TabGroup extends BaseComponent implements
PageAttachListener, IFormComponent {
public abstract String getTitle();
@Persist("client")
public abstract boolean getMinimized();
public void lnkActionToggleGroup(boolean minimized) {
setMinimized(!minimized);
}
...
}
For example if I create 2 TabGroups *without* the @For loop they are
rendered like this:
$TabGroup
$TabGroup_0
But if I create them *with* the @For loop, I get the component twice:
$TabGroup
$TabGroup

Re: Manipulate components inside a @For with DirectLink.
I am assuming that to the @DirectLink you are passing the appropriate parameter(s) that makes it render a unique URL for each iteration? Any code snippets would help.

Re: Manipulate components inside a @For with DirectLink.
I think you will have to look at the parameters that are passed to your TabGroup component. ensure you have cache="false" on all of them in the .jwc file of TabGroup On 8/4/06, Reto Hotz <[EMAIL PROTECTED]> wrote: Hello, In T4, I have a custom component (TabGroup) in a @For loop.
