[struts2] s:generator not generating output
Hello
I'm using Struts2.0.9.
I have to generate a number o inputs acording to a parameter. I tried
using the Iterator Generator Tag on the Struts2 Showcase application,
but the output for me is nothing, null.
This is my jsp code:
<s:generator val="" separator="," count="getGroupSize()">
<s:iterator value="%{top}">
<s:property />
<s:textfield name="input" size="2" value="11">
</s:iterator>
</s:generator>
getGroupSize() is a method in the action that returns an int. I tested
it and is working properly.
What could be wrong, or where what should I look for to find out why
the generator is not working for me?
Any tips appreciated.
Thanks

Well, your example only has one textfield named
"terminal", so you'd provide get/setTerminal methods.
If you want to map it to a collection then expose a
Collection named terminal.
http://struts.apache.org/2.x/docs/type-conversion.html
Towards the bottom it talks about Collection and Map
support.

By the way how do I map many input text fields with the same name on
the action side:
In this case, how do I match, this field on the action side:
<s:generator val="%{getTamanhoGrupo()}" separator=""
count="%{getTamanhoGrupo()}">
<s:iterator value="%{top}">
<s:textfield name="terminal" size="2" value="11">
</s:textfield>
</s:iterator>
</s:generator>
Thanks again!!

You'd probably just want to use the "status" attribute
of the <s:iterator...> tag and use it to build the
name of the text field, although you might want to
consider using array/map notation to clean things up
on the action side.

Yes, I realized that after I posted the question.
generator working ok now...
Thanks, just one more question:
Say I want to generate input fields and name them according to the
iterator value. How would I do that?
<s:generator val="%{getTamanhoGrupo()}" separator=""
count="%{getTamanhoGrupo()}">
<s:iterator value="%{top}">
<s:textfield name="dynaField.area" size="2" value="11">
</s:textfield>
</s:iterator>
</s:generator>
I'd like to create each field with names say area1, area2, area3.

Isn't the "val" attribute what's parsed to create the
iterator?
