NotSerializableException using FormFile
I've set the scope of my form to 'session' to support a "wizard" process. The form defines a property of type org.apache.struts.upload.FormFile. This work fine until I set 'validate = true' on my action mapping. It appears that org.apache.struts.upload.CommonsMultipartRequestHandler$CommonsFormFile does not implement Serializable. Has anyone run into this and what did you do to get around it? Thanks in advance. --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).

RE: NotSerializableException using FormFile [SOLUTION]
1. Create custom MultipartRequestHandler
("MyCustomMultipartRequestHandler") by extending
org.apache.struts.upload.CommonsMultipartRequestHandler.
2. Create inner, private class in MyCustomMultipartRequestHandler that
implements FormFile and Serializable. I simple copied all the methods from
the inner class CommonsFormFile in CommonsMultipartRequestHandler.
3. Override addFileParameter(FileItem item) in
MyCustomMultipartRequestHandler to use your custom handler:
protected void addFileParameter(FileItem item) {
FormFile formFile = new MyCustomMultipartRequestHandler(item);
getFileElements().put(item.getFieldName(), formFile);
getAllElements().put(item.getFieldName(), formFile);
}
4. Add new 'controller' entry in struts-config.xml:

RE: only Strings appear to be validated by Validator [SOLUTION]
My bad...you're right...it does work. Thanks to the miracle of logging, I realized that the integers were being defaulted to zero. As a result, they were in fact passing the validation tests.

repopulating options of when validation fails
Can anyone offer a crafty method of reloading a dynamic collection of into the request scope in case form validation fails and the controller must forward to the 'input' of the action mapping?

populating form fields from request params
I am using the same form to both create and update database entities. The
following is an example of a form field:
And from my struts-config.xml:
... yada, yada, yada ...
As you can see, if this field changes the page is reloaded. Problem: if
${note.auditIdentity} returns null (which would be the case if I was
creating a new entity) the property is not being populated from form bean.
How do I specify that if value is , populate from form bean's
property?

RE: populating form fields from request params
I thought I could resolve this by specifiying:
value='${true ? param.documentStatusTypeId :

...but this did not work. Is the ternary operator not supported yet in
struts-el? (I'm using struts-el-1.1.jar)

RE: Display Mode | Edit Mode
It's not so much a feature as the way you design your Action and ActionForm. I do this with all JSP responsible for creating/editing some persistent business object. What I do: 1. Create two actions named Get[YourBusinessObject]Action and Edit[YourBusinessObject]Action. Both should extends DispatchAction. 2. Create two mappings in your struts-config: /yourbizobj/get and /yourbizobject/edit. Set 'validate' to true on /yourbizobject/edit and define a 'parameter' attribute on each action mapping (i.e. parameter="mode"). 3. Create a form-bean entry in struts-config with the necessary properties. 4. Implement two methods in each Action: add and update. The 'add' on Get[YourBusinessObject]Action is called to do any initialization before return a blank form to the user (i.e. /yourbizobject/get?mode=add). The 'update' on Get[YourBusinessObject]Action is used to retrieve the business object from persistent storage and populate the ActionForm with property values (i.e. /yourbizobject/get?mode=update). The 'add' on Edit[YourBusinessObject]Action is used to insert a new business object into persistent storage (i.e. /yourbizobject/edit?mode=add) while the 'update' used to update an already existing business object in persistent storage (i.e. /yourbizobject/get?mode=update). > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] > Sent: Wednesday, October 22, 2003 12:19 AM > To: [EMAIL PROTECTED] > Subject: Display Mode | Edit Mode > > > Does STRUTS provide any feature so that the same jsp can be used for > showing the page in Display Mode as well as Edit Mode without having to > manually code the same in JSP ? > > Regards > Sreekant G > @ 98404-65630 > > > - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

ValidatorForm losing params when validation fails
The following code fragment is used in a DispatchAction and when the
validation fails, the input form is returned unpopulated because all my form
fields lose the data that was originally sent with the request:
ActionErrors errors = form.validate(mapping, request);
if (!errors.isEmpty()) {
saveMessages(request, errors);
return mapping.getInputForward();
}
My form extends ValidatorForm and I have not overridden reset(). Why is the
form losing it's parameters? Thanks in advance.

RE: ValidatorForm losing params when validation fails
My mapping specifies 'validate="false"' because I have a method in the
DispatchAction, called refresh(mapping, form, request, response) which
adjusts the size of indexed properties in the Form and returns the user to
the same page. I do not want the form to be validated when refresh(mapping,
form, request, response) is called, but I do want validation when the other
methods (i.e. add, update) on the DispatchAction are called. Make sense?

dynamic indexed properties in Form bean
I'm having trouble populating a Form bean that has an indexed (variable
size) nested bean. I'm using an ArrayList inside the Form bean to collect
the nested properties and it's partially working. The problem is that
because the index is variable, I don't know how to correctly size the
ArrayList. As a result, the nested beans are being accessed by their index
inconsistently.I'm trying to dynamically grow it as getBean(int idx) is
called, but it's messy. Does anyone have a good solution for this? Thanks
in advance.
JSP:
Bean fragment:
public class LiabilityForm extends ValidatorForm implements MonthlyDebts,
DispatchForm {
private ArrayList borrowerLiability = new ArrayList();
... more properties...
public BorrowerLiability[] getBorrowerLiability() {
return (BorrowerLiability[]) this.borrowerLiability.toArray(new
BorrowerLiability[0]);
}
public BorrowerLiabilityImpl getBorrowerLiability(int idx) {
BorrowerLiabilityImpl bl;
if (borrowerLiability.size() <= idx) {
borrowerLiability.ensureCapacity(idx+1);
bl = new BorrowerLiabilityImpl();
borrowerLiability.add(bl);
} else
bl = (BorrowerLiabilityImpl) borrowerLiability.get(idx);
return bl;
}
...more method ...
}
