Re: T5 Best way to omit part of result page in output

[Daniel Jue]

Hi, I would try blocks of components at the end of your template, and
a delegate component.

The delegate refers to a method in your page or component class the
template it for.  It returns an Object, which is actually one of the
component blocks. It can also return null and nothing will be rendered
where the delegate tag was.

Alternatively, you could wrap a section of code in an If component.



For instance, to delegate:

<div xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd";>
<tr>
        <td><t:selectdaterangetype /></td>
</tr>
<tr>
        <td><t:delegate to="typeOfDateRange" /></td>
</tr>

<t:block>
        <t:selectmonth />
        <t:selectmonthrange />
        <t:selectquarter />
        <t:selectquarterrange />
</t:block></div>


--------------------------------
The java:

        @Component(id = "daterangetypeSelector")
        private SelectDateRangeType selectdaterangetype;

        @Component
        private SelectMonth selectmonth;

        @Component
        private SelectMonthRange selectmonthrange;

        @Component
        private SelectQuarter selectquarter;

        @Component
        private SelectQuarterRange selectquarterrange;

        public Object getTypeOfDateRange() {
                DateRangeType drt = selectdaterangetype.getSelected();
                if (drt.equals(DateRangeTypeEnum.DR_ENTIRE_FISCAL_YEAR)) {
                        return null;
                } else if (drt.equals(DateRangeTypeEnum.DR_MONTH_SINGLE)) {
                        return selectmonth;
                } else if (drt.equals(DateRangeTypeEnum.DR_MONTH_RANGE)) {
                        return selectmonthrange;
                } else if (drt.equals(DateRangeTypeEnum.DR_QUARTER_SINGLE)) {
                        return selectquarter;
                } else {
                        logger.debug("getTypeOfDateRange() DRT is unknown to 
me, drt="
                                        + drt.toDisplay());
                        return null;
                }
        }
