Problem with range operator
I have a strange problem with range operator, well it is eighter that or I
dont know how to use it.
I have tried the following
<t:loop t:source="1..31" t:value="day">
//html code
</t:loop>
this works but my problem is that the number 31 needs to be dynamic so I
have a property ${lastDayInMonth}
However if I try
<t:loop t:source="1..${lastDayInMonth}" t:value="day">
//html code
</t:loop>
I get
A JSONArray text must start with '[' at character 1 of 1..31
and if I try
<t:loop t:source="[1..${lastDayInMonth}]" t:value="day">
//html code
</t:loop>
I get
Caused by: java.lang.RuntimeException: Coercion of 1..31 to type
java.lang.Integer (via String --> Long, Long --> Integer) failed: For input
string: "1..31"
So what am I dont wrong, ideas?
cheers and tnx

Good catch, Dusko. This remembers me of remembering everyone to never,
never, never ever use expansions (${xxx}) when passing parameters to
Tapestry components.

I made an oversight, try this:
<t:loop t:source="1..lastDayInMonth" t:value="day">
//html code
</t:loop>

Hm...Well it says here that it should
http://tapestry.apache.org/property-expressions.html
"The rangeOp creates a range object that will iterate between the two
values. The upper and lower bounds may be literal integers, or property
expressions"
Also the expression is evaluated properly as it returns the number, but the
conversion is wrong. :S

I don't think you can use it like that, only with fixed values.

The range operator doesn't support dynamic ranges, so the cool option you
describe doesn't exist. Just use what Dusko suggested.

Why don't you just return an array from 1 to lastDayInMonth?
.tml
t:source="rangeOfDates"
.java
public List<Integer> getRangeOfDates()
{
List<Integer> list = new LinkedList<Integer>();
for(Integer i=1; i <=lastDayInMonth; i++)
list.add(i);
return list;
}
