Binding an array and accessing elements of that array in a template

[Russell John-Baptiste <rj...@yahoo.com>]

Sorry if this was answered or shown else where but i'm not seeing it.

I have an array called MonthlyBills[12] in my page class.

In my template, how can I reference each index?

<t:textfield t:id="jan" size="3" value="MonthlyBills[0]"/>
<t:textfield t:id="feb" size="3" value="MonthlyBills[1]"/>
<t:textfield t:id="mar" size="3" value="MonthlyBills[2]"/>
...etc.

does not work.

Cheers.

If you make a method in your page class

public String monthlyBill(Integer index) {
    return monthlyBill[index];
}

I think you can this in the tml file


<t:textfield t:id="jan" size="3" value="monthlyBill(0)"/>

You guys were right...[of course]...

Thanks a million.

Here's my abbreviated final solution:


JAVA:

    @Property
    private Integer index= 0;


    @Persist
    @Property
    Integer year;


    @Property
    private Integer[] funDays = new Integer[13];

    public Integer getFunDay() {
        return funDays[index];
    }

    public void setFunDay(Integer value) {
        funDays[index] = value;
    }

  public String month(Integer num) {
        String month = "invalid";
        DateFormatSymbols dfs = new DateFormatSymbols();
        String[] months = dfs.getMonths();
        if (num >= 0 && num <= 11) {
            month = months[num];
        }
        return month.substring(0, 3);
    }

    public Boolean getDisplayTr() {
        //Logic needed to format information in billableDays in a 3 by 4
table.
        return (index == 3 || index == 7);
    }


TML:

<t:form t:id="ChangeFunDays" t:autofocus="true">

    

        	
            <label for="${month(index)}">${month(index)}</label>
            <t:textfield value="funDay"/>
            <t:if test="DisplayTr">
                

            </t:if>
        
    


    

        	
            <t:submit t:id="submit" value="Save"/>
        
    

</t:form>

Also, a Loop will let you do something like:

<t:loop source="MonthlyBills" value="monthlyBill">
  <t:textfield size="3" value="monthlyBill"/>
</t:loop>

With a property:

@Property
private int /* or whatever */ monthlyBill;
