RE: Logic Iterate in Struts
I am having a problem with this tag as well. My issue it that I set a collection (List) object in the session, the list is not empty yet the result I get is cannot create an iterator... Every example i see says that you should have a bean that holds the collection so the tag uses the property attribute to retrieve the collection but I thought I could just throw a collection object into session and use it with the tag.

The easiest hack(at least in my mind a hack) is to write a

DynaActionFrom.
Then when DynaActionFormClass.newInstance() sets the
inital property values have your converter registered, and
make sure the inital property in the XML for you nested
DynaForm it set to the DynaForm you want to use. Then just
implement the converter to do
public Object convert(Class type, Object value){

DynaActionFormClass.getDynaActionFormClass((String)value).newInstance();
}
I have not tested this yet as I would like a better way
but I would call it a decent 'HACK'.

Subject: Re: Lost in beans
I was thinking about this more on my way home from work.. :) As far as
doing it as a hack I would simply implement and register the converter as
anonymous class.
form-bean
name=NestedTestForm
type=org.apache.struts.action.DynaActionForm
form-property name=value type=java.lang.String /
/form-bean
form-bean
name=TestForm
type=org.apache.struts.action.DynaActionForm
form-property name=nested
type=org.apache.struts.action.DynaActionForm initial=NestedTestForm/
/form-bean
Then in your initServlet()...
import org.apache.commons.beanutils.ConvertUtils;
import org.apache.commons.beanutils.Converter;
ConvertUtils.register(new Converter(){
public Object convert(Class type, Object value){
return
DynaActionFormClass.getDynaActionFormClass((String)value).newInstance();
}
}, DynaActionForm.Class);
Then when the app initialized DynaActionFormClass.newInstance() is called
for a TestForm it looks for a converter for the class DynaActionForm to set
the initial value an passes it the name NestedTestForm.
Like I said before though didn't have time to test this today you might run
into other problems, and it would be much better if there was a permanent
solution..

public String getBiology () { return this.biology; }
public String getChemisty () { return this.chemistry; }
public String getPhysics () { return this.physics; }
public String getEnglish () { return this.english; }
public String getMath () { return this.math; }
public void setName (String name) { this.name = name; }
public void setBiology (String grade) { this.biology = grade; }
public void setChemisty (String grade) { this.chemistry = grade; }
public void setPhysics (String grade) { this.physics = grade; }
public void setEnglish (String grade) { this.english = grade; }
public void setMath (String grade) { this.math = grade; }
}
In your struts-config.xml, define:
form-bean name=studentGradeForm
type=org.apache.struts.validator.DynaValidatorForm
form-property name=grades type=example.StudentGrades[]
size=50
/form-bean
Then, presuming that your Action populates the StudentGrades array with
the student names, in your JSP, you'd say:
html:form action=/some/action
TABLETRTDName/TDTDBiology/TDTDChemistry/TDTDPhysics/T
DTDEnglish/TDTDMath/TD/TR
logic:iterate id=student name=studentGradeForm property=grades
type=example.StudentGrades
logic:notEmpty name=student property=name
TRTDbean:write name=student property=name indexed=true//TD
TDhtml:text name=student property=biology indexed=true//TD
TDhtml:text name=student property=chimstry indexed=true//TD
TDhtml:text name=student property=physics indexed=true//TD
TDhtml:text name=student property=english indexed=true//TD
TDhtml:text name=student property=math indexed=true//TD/TR
/logic:notEmpty
/logic:iterate
/TABLE

Subject: RE: multi row / multi col input forms
I understand what he is saying about setter methods perhaps I
am not explaining the problem correctly
The exact example is I am trying to display a listing of a
dynamic number of projects with hours assigned to them by day
for a given week, the user can then update any of those
fields to make changes, some of those fields may be blank
which means the browser will not send them to the server
which puts the rows / cols out of balance.
I am using the logic iterate tag to build a row which looks like
someText someMoreText inputBox1 inputBox2 inputBox3 inputBox4
So for two rows I get
someText someMoreText inputBox1 inputBox2 inputBox3
inputBox4 someText someMoreText inputBox1 inputBox2
inputBox3 inputBox4
This means that from a vertical perspective the boxes have
the same name ( is there a better way to do the names?) If a
inputBox doesn't contain anything I can't tell which one it
really was except which column it didn't come from.
Clear as mud?

Subject: REPOST: Forcing the ActionForm to populate a field
before the
other
I would like to have a setter method called before another. What's
the best way to do that in the ActionForm
There are no guarantees on the order that the setters are
called. This is for two reasons:
* There is no rule in the HTTP or HTML specs defining the order
in which the request parameters are sent, so it's totally up
to the client. And they really do operate differently.
* There is no rule in the servlet spec saying that the input order
has to be preserved, so it's totally up to the container to decide
how to implement this. And they really do operate differently.
More fundamentally, though, the only reason that the setter
order would matter is if there are side effects (setting one
property affects the semantics of setting a different one).
Designing your form beans in this way is a very poor
architectural decision -- the whole point of a form bean is
to simply represent the input values that the user actually
entered
multi row / multi col input forms
Is there a way to get the inputs from an html form that has something like: col1col2col3 row x x x row x x x row x x x where x may or may not be entered and the input boxes are named like col1, col2, col3. So if a user enter a number in row2, col1 and row3, col1 how to tell that it was row 2 and 3 that where entered because hen inputs are named the same the parameters come back to the server as an array but there is no guarantee which order they were in especially if the first one was blank as in this case. The array looks like I had two entries in col1 but the numbers are in position 0, and 1. which they should be in position 1 and 2. Any thoughts.

RE: multi row / multi col input forms
OOPs! If I were to RTFM I would have found it, the tags have the indexed attribute. Thanks! -Original Message- From: Khalid K.
