RE: multi row / multi col input forms
We are having trouble solving the same problem of updating the fields for a
DynaActionForm's indexed properties. We are running on Struts 1.1 beta2.
Should we be using the latest beta3 to get this to work?
Our configuration basically follows that of James' below.
We defined a Bean named EditFormIndexPropertyBean, which will be the
elements of the DynaActionForm's array property
The form-bean is configured as:
form-bean name=categoryIndicesEditForm
type=org.apache.struts.action.DynaActionForm
form-property name=categoryIndex
type=com.cgc.approve.struts.beans.EditFormIndexPropertyBean[]
size=10/
/form-bean
The form's iteration in the JSP look like:
logic:iterate id=categoryIndex name=categoryIndicesEditForm
property=categoryIndex
type=com.cgc.approve.struts.beans.EditFormIndexPropertyBean
indexId=index
logic:notEmpty name=categoryIndex property=name
td
html:text name=categoryIndex property=name indexed=true/
/td
/logic:notEmpty
/logic:iterate
Unlike James' example, we had to name the form-property 'name' attribute
the same as the logic:iterate 'property' attribute, in this case
categoryIndex. Otherwise the PropertyUtils could not find the DynaForm's
property by that name.
Here's what appears to be the problem: The DynaForm's array property
'categoryIndex' is not being populated with the elements of our
EditFormIndexPropertyBean. The array property is instantiated with the
correct name, however it is empty. The DynaActionForm then attempts to set
the property with name=categoryIndex at index 0 with some value:
DynaActionForm.set(String name, int index, Object value) {
DynaProperty descriptor = getDynaProperty(name);
Object prop = dynaValues.get(name);
}
This causes a null pointer exception as there are no dynaValues to retrieve
(no EditFormIndexPropertyBeans in the array property) .
We have used successfully indexed properties for DynaActionForms such as
String[] and Integer[] and other primitive type wrapper classes. How can we
get our DynaActionForm to work use a property that consists of an array of
user defined classes?
A side question for any who might know. When using a String[] property it
is not necessary to set the size attribute. Is this needed for user defined
classes?
Thanks for any help,

Here's one way to do it:
Let's say you want to be able to record the grades of some students
across a number of classes.
First define a Bean called StudentGrades:
Package example;
public StudentGrades {
private String name, biology, chemistry, physics, english, math;
public String getName () { return this.name; }
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

Re: multi row / multi col input forms
This works fine with either!
Ex:
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/basicportal/ROOT/portlets/cms/ContentApprovePortlet.jsp
Make sure you implement a collection and unit test the formbean outside
of Struts before doing any beans, including multi row.

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.
