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;i<10;i++) {
for(i=5;i<15;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);

Andy, I will give that IntIterator a try... but I have a parameter
in OGNL called tableSize. How do I pass this into the IntIterator
constructor?
source="ognl:new IntIterator(1,ognl:tableSize)"
?
thanks for helping

tassle component LOOP is for 3.0.
No indicator it is for T-4.1.2
Still blue in the face,.,.,.

All I am looking for is a Loop component.
Tap-4.1.2 has none.
Unless someone wants to point it out and skip all the heck.

Thanks Bob but I need to span the whole list.
Thanks Andy but I how do I cause a for loop to iterate N iterations
independent of any collection?
I guess I am looking for static iteration independent of any
collection. I am inheriting from baseComponent so I am not inclined
to do this as a pure java widget. I need to operate off the template.
Would @Deletagor be an option?

I can whip off a solution in JSP while I am typing...
<span jwcid="[EMAIL PROTECTED]" source="ognl:collection"
value="ognl:currentObject" index="ognl:index">
<%
for ( int i = 0; i < 3; i++)
spit out <TR><TD>...</TD></TR>
%>
</span>
Why is it so hard to do such a fundamental thing in tapestry?

martino I am already using the FOR component on my list.
I have a select component that sets a tableSize at the top of page
for a list==100.
If tableSize = 10, then I want to render 10 items within a <TR></TR>
And continue until the list is exhausted.
Then I will see 10 rows. Right?
FOR does not permit this to happen. It is blind.

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 <tr><td></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?
