Re: loop inside loop

[Jan Fryblik]

I know, i only wanted to see a practical advanced usage of tapestry.  
Everywhere is a lot of basic examples, but i haven't found clear example  
of nested loop in loop.

My issue is with handler onAddRowFromTimeRangeLoop(OpeningItem  
openingItem). Parameter "openingItem" is always null, encoder of outer  
loop is not called, but I dont know why. Probably i've overlooked  
something.

.tml

<t:ajaxformloop t:id="openingItemLoop" t:source="unsavedOpeningItems"  
t:value="openingItem" t:encoder="openingItemEncoder">

    <t:ajaxformloop t:id="timeRangeLoop" source="openingItem.timeRangeList"
        t:value="timeRange" encoder="timerangeEncoder" t:context="openingItem">

        <div class="time-range-item">
                <t:cb.businesshours.timeperiod period="timeRange"/>
        </div>

    </t:ajaxformloop>

</t:ajaxformloop>


.java

    @Persist
    @Property
    private List<OpeningItem> unsavedOpeningItems;

    @Property
    private OpeningItem openingItem;
    @Property
    private TimeRange timeRange;

    @Inject
    private TypeCoercer typeCoercer;

    private ValueEncoder<OpeningItem> openingItemEncoder;

    public ValueEncoder<OpeningItem> getOpeningItemEncoder()
    {
        if (openingItemEncoder == null)
        	this.openingItemEncoder = new  
OpeningItemEncoder(unsavedOpeningItems);

        return openingItemEncoder;
    }

    public ValueEncoder<TimeRange> getTimeRangeEncoder()
    {
        return new TimeRangeListEncoder(openingItem.getListableId(),
                                        openingItem.getTimeRangeList());
    }

    @SetupRender
    public void initialize()
    {
        if (unsavedOpeningItems == null)
            unsavedOpeningItems = openingHours.getOpeningItemsList();
    }

    public OpeningItem onAddRowFromOpeningItemLoop()
    {
        OpeningItem periodicOpening =  
entityFactoryService.createOpeningItem();

        unsavedOpeningItems.add(periodicOpening);

        return periodicOpening;
    }

    public TimeRange onAddRowFromTimeRangeLoop(OpeningItem openingItem)
    {
        List<TimeRange> timeRangeList = openingItem.getTimeRangeList();
        TimeRange timeRange = entityFactoryService.createTimeRange();
        timeRangeList.add(timeRange);

        return timeRange;
    }



Thanks,
Jan

Hi guys,

could you please provide me a example how to work with AjaxFormLoop  
inside
AjaxFormLoop? Or more generaly loop inside loop. I'm stuck with it. I
guess, it's a bit advanced use of tapestry. Thanks in advance.


Best Regards,
Jan
