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:
<span jwcid="@Util:TabGroupView" source="ognl:items"/>
TabGroupView.html:
<span jwcid="@For" source="ognl:source" index="ognl:index" value="ognl:group">
<span jwcid="@TabGroup" title="ognl:group.title"
minimized="ognl:minimized" parameters="ognl:new
java.lang.Object[]{index, minimizedMap}"
listener="ognl:listeners.linkActionToggleGroup"/>
</span>
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:
<a jwcid="@DirectLink" parameters="ognl:parameters" listener="ognl:listener">
<span jwcid="@Insert" value="ognl:title"/>
</a>
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. :)
Greetings

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.
