I have gone through Pawel's example and it is not working for me.
Here is the iterator:
<s:iterator value="allCustomers" id="iter" status="table_stat">
I created three methods in my action class:
public boolean getCanEditCustomer()
{
return false ;
}
public boolean getCanEditCustomer(Integer anInt)
{
return false ;
}
public boolean getCanEditCustomer(Customer aCustomer)
{
return false ;
}
These are dummy methods just to see if everything will work. I set an Eclipse
breakpoint on each return statement. So in theory, Eclipse should stop on one
of the statements whether I pass in nothing, an integer, or a Customer object.
The results are:
<s:if test="canEditCustomer"> (This stops in the first method)
<s:if test="canEditCustomer()"> (This never stops)
<s:if test="canEditCustomer(5)"> (This never stops)
<s:if test="canEditCustomer(iter)"> (This never stops)
So it seems like no parameters are being passed in; in fact when I use the
braces to indicate no parameter, that doesn't work either.

Subject: Re: Question about 'if' tag
In addition to what Pawel is saying, be careful that you also check
the 'canEditCustomer(target)' call in the target action since there is
nothing to stop someone from figuring out the URL pattern and editing
people they weren't intended to edit.
