Hi Werner
If I understand it correctly what you suggest will perform a NESTED loop
which means that if I have j values for property x and k values for property
y then the LOOP will produce j*k lines and I don't want it to behave like
that. The properties have the same number of elements t and I want the LOOP
to produce only t lines.
Class Bean {
Vector numbers;
Vector strings;
Integer getNumbers(int index ) {
return numbers.elementAt(indesx);
}
String getStrings(int index) {
return strings.elementAt(indesx);
}
}
I want my dynamic page to display lines which contain a number and matching
string on each line.

Subject: AW: Loops on multiple properties
Hi Arie,
why don't you want to use two nested loops on the same bean?
since they use different properties they wouldn't interfere with each other
and create those properties' cross product (creating all inner values for
every
outer iteration) - I asume that is what you seek.
<LOOP PROPERTY=beanA:prop1 PROPERTYELEMENT=x>
<LOOP PROPERTY=beanA:prop2 PROPERTYELEMENT=y>
x = <display PROPERTY=x> / y = <display PROPERTY=y>
</LOOP >
</LOOP >
providing a specific language construct within JSP for exactly the same
result would just
would just increase the JSP-Handler's complexity, risk for bugs, effort to
learn....
bye, Werner
