RE: does tapestry 4.2 have an iterator component
Thanks Martino but FOR does not cut it. It blindly iterates a collection from 0..N. I need a component with which I can manipulate the front end starting index and jump out break at a specified numeric index. Example: I have a list of 100 . Now I want to render trtd/td/tr and show 7 elements and iterate again to do the same until the list is exhausted. I cannot do this with FOR. ?

Re: does tapestry 4.2 have an iterator component
In fact it seems to me you should solvee your problem with some easy page method creating the list to be iterated by the for each time you reload the page. So you have your big list in one property and another method (possibly reading other properties/parameters) will slice the big list to provide for the actual list iterated by for (finally it's still a list...). Don't mix the complexity of your controller/model with the simplicity of tapestry components :-) On 10/8/07, Ken nashua [EMAIL PROTECTED] wrote: Thanks Bob but I need to span the whole list.

Re: does tapestry 4.2 have an iterator component
Ken, you're right - T4.1.2 doesn't have a Loop component
it has always had a @For component
Here's a way to turn For into Loop (adjust for JDK1.5)
public class IntIterator implements Iterator{
private int _start, _end;
public IntIterator(int start, int end) {_start=start;_end=end;}
public boolean hasNext() {return _start_end;}
public Object next() {return _start++;}
public void remove(){}
}
span jwcid=@For source=ognl:new IntIterator(1,100) ...

Example: I have a list of 100 . Now I want to render trtd/td/tr and
show 7 elements and iterate again to do the same until the list is exhausted. I cannot do this with FOR.

I would like to do some iteration like a true for loop with front, back and
computable boundaries.
Is there such a component?

Re: does tapestry 4.2 have an iterator component
The outer loop's index paramter and the inner loops index
parameter are independent. However, the property to which they are
bound in your page is up to you.
So, in your example, where both index parameters are bound to the
index property, you're going to get collision, just as you would with:
for(int i=0;i10;i++) {
for(i=5;i15;i++) {
}
}
You'll need two distinct index properties here:
.html:
span jwcid=@For source=ognl:collection
value=ognl:currentObject index=ognl:outerIndex
span jwcid=@For source=ognl: new IntIterator(1,100)
index=ognl:innerIndex
...
/span
/span
.java:
public abstract int getInnerIndex();
public abstract void setInnerIndex(int idx);
public abstract int getOuterIndex();
public absract void setOuterIndex(int idx);
