Re: Problem assiging elements in to list
Just out of curiosity, when you say "All of this is done automatically by the
framework" do you mean if you populate from a form? or how do you mean the
framework does this automatically?

That would create a list of empty Person instances (then persist the last
empty Person, but I'm assuming that's a typo).
All of this is done automatically by the framework.

You never really state how you're expecting the list to be filled: is this
from a form with multiple Person form fields, or...?

Re: Problem assiging elements in to list
HI Vamsi,
by the time you get to the for loop I don't see the list initialized, unless
you are doing this from your jsp I don't think it will work as how you have it,
a better way would be with a normal for like this :
for (int index = 0; index < someLimit; index++) {
Person person = new Person();
persons.add(index, person);
_logger.error("Person ::" + person);
e.persist(person);
}
hope this helps.

Hi all,
I have a requirement where I need to assign a Objects to a list.
I tried the example given in showcase there is working (in the site).
But It is not assigning to that list
I am also attaching code for your refernce.

[OT] Re: A try catch and return question
The blocks you mention achieve different results. In the FIRST block you will
have to add a return statement for when an exception is thrown, this allows you
to set the theReturnedObject to a value for when an exception is thrown. In the
SECOND block if you are modifying theReturnedObject in the try block then you
will have to take into account that an exception might occur and that this
exception might affect the value of theReturnedObject.
Oh and by the way, this is a struts mailing list :-)

Oh and by the way, the logic tag is gone, IMO the struts2 guys did not want to invent the wheel again.

RE: [S2] Problem setting radio to default value from a Collection
Worked around this, putting this piece of code before
the end of my body tag
in the jsp page:
document.getElementById('answer<s:property
value="answer"/>').checked=true;
However I don't like it. According to the
documentation the radio should
check the default to the answer value, because it has
the same name as the
property in my action, but it is not working this way.
How can you set a
