Re: Nested Iterate Tag and indexId problem
On an interesting note, we had to do alot of this as well where the
variable came from another tag(s).
I stumbled across this: I found it a bit cleaner
function('1','2','')

I figured out the problem.
This will not work even though the rtexprvalue is set to true in the tld.
However, this will work...
<% String onchangeCall = "function('1','2','" + variable + "');" %>
/>
I can't use a scriptlet for just a portion of the assignment. It has to
be all or nothing. In the first version it just treats everything as a
string.
In the second version it evaluates the runtime expression.

RE: Nested Iterate Tag and indexId problem
I would try changing
to
' />
Of course if 'variable' is a property of the object in the current iteration, you'd
change it to
' />
where 'x' is the value of the 'id' attribute of your .

Nested tags were available as a separate download prior to 1.1. I have
been using them quite succesfully up until now.
What I really need to do is this
I have several rows of data which are editable in individual text boxes.
For each row I have a checkbox.
When the user makes a change in any of the rows I need to set the check
box to selected.
The probblem is that I am unable to get the nested:text onchange event to
evaluate a run time expression. It just dumps my code out as it.
So this...
results in html something like this...
instead of
onchange="makeEditDirty('a','b','0');" />
I need to be able to pass in the row number to this script method.
Regards.

Re: Nested Iterate Tag and indexId problem
I don't know nested tags on version 1.02 of Struts, and perhaps it's a
stupid question, but are you sure that it is possible to use scriplet values
on the onchange parameter of the tag: is set to "true" for
this attribute, on the .tld file of the taglib ?

Re: Nested Iterate Tag and indexId problem
Perhaps I made a mistake, but nested tags are available since Struts 1.1: I
think they are not available on Struts 1.02.

RE: Nested Iterate Tag and indexId problem
The problem is an incompatiblity with javascript names and nested tags.
The nested tags create names like
property.nestedproperty
When you go to use this in javascript you do
document.forms["yourform"].property.nestedproperty.{method}.
Javascript blows up at this point.
You need to get a pointer to the form field either with 'this' or
searching through the form fields on an indexed basis till you find the
one you are interested in.
Here is my little javascript to find a field.
// determine a field from it's name
function Struts_eval(fieldName, fieldCount) {
var objWrk = null;
if (fieldName == null)
return objWrk;
if (fieldCount == null)
fieldCount = 1;
// now try the rediculous eval
var findCount;
findCount = 0;
var len;
for ( var i = 0; i < document.forms.length; i++ ) {
for (var j = 0; j < document.forms[i].elements.length; j++) {
if (document.forms[i].elements[j].name == fieldName) {
if (++findCount == fieldCount) {
objWrk = document.forms[i].elements[j];
return objWrk;
}
}
len = document.forms[i].elements[j].name.indexOf(fieldName);
if (len < 0)
continue;
if (len + fieldName.length ==
document.forms[i].elements[j].name.length) {
if (++findCount == fieldCount) {
objWrk = document.forms[i].elements[j];
return objWrk;
}
}
}
}
return objWrk;
}

Subject: Nested Iterate Tag and indexId problem
I am using the nested tags with Struts 1.02.
I want to be able to dynamically set a call to a javascript function. I
want to pass in the row number to the function.
I currently have
');"
onkeyup="return autoTab(this, 1,
event);"
/>
This does not work.
I have also tried
');"
onkeyup="return autoTab(this, 1,
event);"
/>
It does not work either.
It is looking to me like a bug with the nested tags. They sure have
been
very useful. I would hate to change all the code back at this point.
Why can I use a regular jsp <%=idx%> to get the value of the indexId
from
the iterate tag?
Thanks.
