RE: Handling Multipart forms (sort of Wizard)
Hi, I'm working on the documentation now and feel it would only be fair to contribute some of these diagrams back to the struts community. It will probably take me a couple of days to get it sorted though. I hate documentation, grg. Cheers, Andy S p.s. I think it has more to do with my style of writing than your lack of smartness - did I mention that I hate documentation?

It works on the principle of page numbers and has only one action per wizard regardless of the number of pages involved. There is a base class form which has a validate method that can validate any form in a generic method, validating only the fields on the current page, and after completion of the wizard does a "finalValidate" check to make sure nothing remained unvalidated (this is necassary due to the dynamic way in which the page by page validation is executed). In our system we have a data dictionary most fields represent a field in the data dictionary - this link to the data dictionary which performs the validation for that particular type of field e.g. a PostCode validator. The data dictionary also returns the possible values for fields which are of a select variety - the labels are then looked up based on the current language, the field type and the value. If a field is not representing a data dictionary member a localValidator must be written in the form object name e.g. validatePostCode. CrossFieldValidations are executed in a similar manner and we have added functionality to ensure crossFieldValidations are run at the correct time (one of the tough bits!). The base class Form (which extends ActionForm) is then subclassed, one per wizard, the member field objects are defined in the initialise method, the fields have objects which have attributes and methods as necassary to complete the functionality. The getters and setters in the wizard form fetch the correct field from the collection and set/get the value to return to the struts tag libraries/other code. Each form is then sublassed once per channel (Wap, HTML and iDTV - all of which we have working). The subclass specifies to the field objects which page each field is on for that particular channel, this enables the validation to work correctly and also means business validation errors from the EJB container after wizard completion and submission can be directed to the correct page for display. The sublassed channel specific form can add extra fields and specify which page they lie on (or set a field to be internal). An example of this is that the base class of a transaction may contain a single date field. On the Web channel this is actually 3 fields (day, month, year) on the Wap channel this is just a selection of today/tomorrow etc. As each page is submitted a method on the channel specific sublass called mapData is called - in the Web channel this maps the 3 fields into the 1 date field, on the Wap channel it maps todays date or tomorrows date into the base class single date field. The validation is then run and any errors are displayed by including the error tag to the base class date field (although a mapError method could be called to map it to the year field in the web channel etc.). When a form is prepopulated from stored records before the user begins to complete it a mapInitialData method is called - in the web channel this would pre-populate the day/month/year fields based upon the date value in the base class - the reverse of mapData. We have many more obscure mappings as well as simple date ones. There is an ActionMapping per channel for each transaction and as well as having keys for when the Action has completed such as success, home, error also have entries, one per page of the wizard like this . Using this we have host of methods on the form (although these might be better located on an ActionMapping sublass) which are all used in a completely generic and centralised way (in the ActionClass we created by extending the Action class) page flow is controlled using methods such as getCurrentPage, getNextPage, isLastPage, getNextPageActionForward, etc etc. The benefits of this design are that no matter what channel is running, you can be sure tha

After going thru the suggested options, I think the 2nd option is better. This is because, since it is a wizrd, so there is back and next buttons to correct the data in different JSPs before saving. If we need to handle this using child-mother beans then we need to keep child beans also in the session scope. This is because each child bean is associated with one form so to get the entered data after forwarding 2-3 pages , if we again want to come back to the 1'st page, data should be preserved. Although, we can do it by copying mother bean properties back in the child bean..

Re: removing request parameters before action forward
I have a similar question which perhaps could be asked at the same time. I have a JSP that submits to an Action with a certain set of parameters, the ActionClass then forwards to another ".do" if succesful, when this ".do" is called the corresponding form bean is created and populated with request data. However the data in the request object was never meant for that form bean it was only for the form bean belonging to the original ".do". A side affect is that if the 2nd bean has any matching data names to the first it will get populated with data. I understand you could make sure that all the names were different but that rather detracts from the atomicity of the two ".do" actions. Am I looking through something obvious? Anyone solved this before?

What I'am trying to do: A jsp page displays some items. If one clicks an item, the same page shows again with an incremented item count. The -tag includes the item id as an url parameter. The perform method of the action class looks for this url parameter, increments the corresponding item count in the action form and forwards back to the jsp page. Everything works fine, but the url parameter (the complete url) is also forwarded to the jsp page. Sometimes this doesn't matter (or even should be like that), but in this case, pushing the reload button increments the item count again. Could anyone give me a hint or even a solution?

RE: Can an Action forward to another Action?
I've been doing this and it works fine except for one thing, and maybe someone can help. When you go to the next action, the request object is still in scope and has not been cleaned. Therefore any data from the request that happens to have a setter in the 2nd form bean gets auto-filled into the form belonging to the 2nd action as well as the first. Any ideas of how to clear the request object or tell struts not to autopopulate after an action forward?

Subject: AW: Getting hold of the session
Hi Andrew,
why don?t you populate your beans before you call your jsp (where i asume
your getter methods are being called). i.e. let your ActionClass gather all
customer information, prepare your bean, drop it in the session and access
it in your jsp.
If you want to directly populate your ActionForm check the mailing list.
The
topic was discussed a few times.

Betreff: Getting hold of the session
Hi,
One of my getter methods (called by struts) needs to get hold of an object
in the Session so that it can populate the values of a drop down box based
upon a call to the "customer" object which is stored in the session.
Unfortunatley struts does not pass my method the request or the session
object and neither does it pass either of these to the form constructor so
I can't store a local reference to it in the form.
This problem must have been encountered and solved by others already, does
anyone have any suggestions?

You can set the transactional token in your edit Action class with

adding an ActionError in the Action
Hi, If I form validates itself OK but subsequently the Action needs to raise an input error to the user, in my case security failed, how is it possible to add an ActionError for the errors tag to pick up. The only way to give struts a collection of ActionErrors is by returing it from the ActionForm.validate() method. I presume if I know the name of the ActionErrors bean which the error tag accesses I could manually create it in the Action and add it to the correct scope so that the errors tag could pick it up.

This is the behaviour as I understood it and it leaves no way to tell if a user has left a checkbox selection blank without knowing specifically that you were exepecting it on that page, something my current design dosen't enforce with other types of input (nice and dynamic). I may be able to extend the Form tag to include some onSubmit csjavascript that searches through fields and makes sure a blank string is submitted if it has been left unchecked. We shall see.

null or empty string
Hi, I have written a dynamic validation routine which is based upon only validating the fields that have been submitted and then "mopping up" later. This only works because you can tell the difference between a field being submitted and left blank (value = "") and a field not being present in the request (value = null). This is true for input type="text" but is not true for input type="checkbox", has anyone come accross this problem before? any solutions ideas? Cheers, Andy S
