ActionForm String[]
Hello, I am working with a dyanmic form, that generates n checkboxes (for each row of my set). Using a String[] type in the action form, I´d been able to retrieve the data. Now, I´m trying to pre-populate these checkbox values correctly, via ActionForm reset method, but can´t figure out. Instanting a bogus vector and seting some values to it doens´t work... Can I do it without messing with my jsp?

html:link page=%= myForm.getObjectLink() %
c:url var=link url=${myForm.objectLink} /

Subject: Bean Population When Form Cancelled
Hi all,
I have a form that uses validator to check for simple validation like
making
sure that a cash amount is a double. I have the cancel button on the
form
set so that if it is pressed that validation does not take place. This
is
great except when you type a letter into the cash text box and then
press
cancel. The form gets returned along with the invalid cash amount, the
BeanUtils attempts to populate the form and the whole thing falls over
with
an exception.
Does somebody have a strategy for dealing with this situation? Is there
a
way of telling struts that if the cancel button is pressed that NO bean
population should take place?
All help appreciated.
Cheers
Tom

You could use the referer header to create an action forward based on that value.

Re: [Shale] Property in ViewController Backing Bean is null
Hi again, I tried the whole weekend, but I didn't get any results other than those mentioned in the email below. Shall I send some code to illustrate the problem or is it really so unusual, what I'm trying to do? Thanks a lot for any help! Peter Good morning Craig, thank you, I think I'm making a progress with your help. I set the immediate flag to true for my commandButton, and my method gets executed as I wanted it to do. In the edit method I set an attribute of the backing bean to its correct value (the person that should be edited in the form), and this attribute is set correctly (in the prerender method I see its correct values). But the form is not being filled with the values. I read the chapter about the lifecycle of a JSF page in the J2EE tutorial, but didn't find the information where to tweak the application to set the actual form values. In my opinion this should happen in the Update Model Values phase, and that this phase has to be executed, when no errors occurs at validating the request parameters. But it seems this is not the case. Could you please help me again and push me in the right direction? Thanks a lot, I will name my first child after you, if my wife doesn't complain. :) Have a nice weekend!

That seems to be the problem, because all of my form input fields are required fields and the messages get filled. Is there a way to skip validation on some actions? I would like to validate the form when submitting it, but not when I select one item in a list to fill the form with. Or is it standard behaviour to extract such data tables to an extra form in the .jsp? Thank you very much, what I wrote so far in this group is really excellent! The standard approach to doing this is to mark the commands you want to work this way with immediate=true. This causes the corresponding action to fire immediately :-) ... during the Apply Request Values phase of the request processing lifecycle, which comes *before* Process Validations. The most common use case for this is a Cancel button ... you don't want to have your validations executed if you're cancelling the input. But the same principle applies to your scenario. Good night! Peter Craig Craig McClanahan wrote: One thing to double check is whether some validation rules are failing, which would cause the action method call to get bypassed.

A new feature to RSA (I guess new to eclipse 3.x) is the ability to create links outside of a project. This is pretty handy for linking in source folders that are not under a project. Pull up the properties for a web project and select Java Build Path and the Source tab, and then click on the add folder button. Select the project root folder and click create new folder (only works for the root folder). Use the advanced button to link in a source folder. This is also an option for folders but it doesn't seem to work for the WebContent using just eclipse (haven't tried it under RAD). You might try adding the test source folder to your web project and then just exclude it from the build path using the source tab. Then create a test project that has links to the source in the other project. To make this work on multiple workstations I think you would need to use a link variable instead of a path. I'm sure there are several other options. You might look at the Project Reference too.

Re: memory usage

As long as you are arriving at the settings page via an action, can't you just call the getInputForward() -- the method that the validate stuff calls to return to the starting page if there were errors; this seems like it would easily work.

Re: [Shale] Property in ViewController Backing Bean is null
I think you may running into a simular problem that I ran into. I have the following scenario: page 1 has the user choose from a list of options. On page 2, the form saves the selected option of page 1 in a hidden field in its form. In addition the selected value from page 1 is used to populate a pull down on page 2. So the user hits the submit button on page 2 to save the changes and KA-BLAMMO, I get a NPE. What was happening was the JSF was attempting to Validate the pulldown values in the Validation phase. This was before any of the hidden fields were set. So because the hidden fields weren't set, the retrieve of the pulldown was failing. I saw 1 of 2 solutions: 1) Turn off the validation of the pulldown. Because, hey... why would I need to validate a pulldown? - it isn't like a user can mistype something. OR 2) somehow get the hidden fields to be set before any retrieval of the pulldown is made. The JSF mailing list from Sun gave no help for turning off the validator for the pulldown. So I had to do the following, for which I give myself a big Capital H for HACK. In the contructor of the backing bean, I grabbed the request parameters myself and called the setters from there for the values that were needed to get through the validation of the pulldown. Perhaps someone here can help turn off the need to retrieve the pulldown values in the validation phase. I hope this will help your situation, as well.

Re: Problem deploying older versions of my WAR in struts project
Thanks a bunch! I think JBoss probably behaves the same as Tomcat in this instance. Since my JSP files had an older timestamp, they were not being updated. That is, after all, somewhat intuitive. What had really been puzzling me was why I couldn't manually clear all my stuff out of JBoss, and then load the old archive without having to worry about touching files and timestamps. Turns out I had noticed the tmp folder, but had not realized the work folder also had to be cleared. Now, with your help, I can finally load these older versions. Thanks for helping me once again become Master of my domain well, for struts anyhow :P -Jeff B Laurie Harper wrote: I'm not too familiar with JBoss, but the Tomcat solution would be to clear the 'work' directory.

Shale: postRender method?
Hi All, I was wondering if there is an easy way to get a postRender method to be called in my Shale ViewController. Is a new Phase Listener the only / best option? Perhaps I can extend a Shale class to also call a postRender method? Here is my scenario: I have the concept of an ErrorEventCollector in the ViewController. Basically, the collector is passed around in the model calls to capture errors during the model execution. This might include errors caused by validation checks on the retrieved data from the DB, as well as any exceptions. These events can be generated in any phase - init, validation, application, or render. In my BaseViewController - I want to have the event collector checked for any events. If there are events in the collector, then I want to create FacesMessages for each event. I tried putting the check in the Shale destroy method, but the messages weren't being displayed by the JSP. So It seems I need to have this check as the last step in the render_response phase. Thanks for any help.

Ah, OK. Then the t:saveState component from MyFaces would be more
appropriate for the problem being discussed. We've used this in several
applications, with no problems. All of our beans (except maybe two of
them, that contain more static values) are request scope, but they carry
their values through multiple pages of a conversation.
All of the patterns that work for non-JSF-based webapps all work with JSF as
well -- for example:
* session scope state variables
* hidden fields in input forms
* request parameters on generated URLs
* cookies
Shale Dialogs is an instance of the first one, in that it gives you a sort
of scope longer than a request, but shorter than a session, without you
having to be responsible for cleanup. It's nice when you have your
application organized into a series of conversations with the user that
have well defined beginning and ending points.
One idea I've seen discussed, but haven't seen actually implemented yet,
would be a JSF-specific implementation of the flash concept in RoR, where
it keeps state information around for exactly *one* more request for you.
It should be easy to do this with a specialized variable resolver or
something ... I'll think about how to do that when dialogs are heavier
weight than you really need. Something along the lines of this in the
second page:
h:outputText value=#{flash.savedCustomerName}/
where savedCustomerName was stored away (until the next request) by some
TBD mechanism.

RE: [shale]Help needed for Clay

In the web.xml this file is declared: !-- Clay Configuration Full XML view Resources -- context-param param-name org.apache.shale.clay.FULLXML_CONFIG_FILES /param-name param-value classpath*:org/apache/shale/usecases/symbols/clay-tiles-config.xml /param-value /context-param This file exists in the classpath.

The jsfid is like the tiles path attribute. The page above extends basePage. This definition is in the common's config file and it's declared in the web.xml !-- Clay Common Configuration Resources -- context-param param-name org.apache.shale.clay.COMMON_CONFIG_FILES /param-name param-value /WEB-INF/clay-config.xml, /WEB-INF/clay-symbols-config.xml /param-value /context-param The basePage defines default symbol values: !-- Base layout defintion -- component jsfid=basePage extends=clay attributes set name=clayJsfid value=/symbols/layout.html / /attributes symbols set name=@title value=Default Title/ set name=@leftContent value=page3LeftPanel/ set name=@headercontent value=/symbols/header.html/ set name=@logo value=http://struts.apache.org/images/struts.gif/ set name=@bodycontent value=space/ set name=@footercontent value=footerPanel/ /symbols /component And, the base layout is a generic template: html headtitle@title/title/head body form table border=1 tr td id=leftContent rowspan=3span jsfid=clay clayJsfid=@leftContent allowBody=falseLeftbr/Content/span/td td id=headerContentspan jsfid=clay clayJsfid=@headercontent allowBody=falseHeaderbr/Content/span/td /tr tr td id=bodyContentspan jsfid=clay clayJsfid=@bodycontent allowBody=falseBodybr/Content/span/td /tr tr td id=footerContentspan jsfid=clay clayJsfid=@footercontent allowBody=falseFooterbr/Content/span/td /tr /table /form /body /html There's a view other details but that's the general ballpark.

Yes, but t:saveState requires that you get the page author involved. From
an architectural viewpoint, I don't think that's necessarily the right
answer (in many cases) where the state being saved and restored is server
side model state as opposed to view state.

[shale] Clay component definition for t:validateEqual
Hello all, I'm trying to use the tomahawk validator for making sure two fields have the same value for users entering their password. There isn't a definition in the clay-config.xml in the Shale or MyFaces JIRA tickets so I'm trying to create one. So I went ahead and created one: component jsfid=t:validateEqual componentType=??? attributes set name=for bindingType=Early / /attributes /component I wasn't sure what to use for the componentType attribute of the component. I thought I'd try setting the componentType to the fully qualified class name of the component itself, e.g org.apache.myfaces.custom.equalvalidator.EqualValidator. But that doesn't work. It blows up with the following exception: 2006-02-14 15:24:21,630 14340 ERROR [http-8443-Processor25] org.apache.shale.clay.component.chain.CreateValidatorCommand (CreateValidatorCommand.java:90) - Cannot create validator jsfid=t:validateEqual componentType=org.apache.myfaces.custom.equalvalidator.EqualValidator extends=t:validateEqual allowBody=null facetName=null javax.faces.FacesException: Unknown validator id 'org.apache.myfaces.custom.equalvalidator.EqualValidator'. at org.apache.myfaces.application.ApplicationImpl.createValidator(ApplicationImpl.java:621) at org.apache.shale.clay.component.chain.CreateValidatorCommand.execute(CreateValidatorCommand.java:87) at org.apache.commons.chain.impl.ChainBase.execute(ChainBase.java:166) The usage of the validator is simply: component jsfid=inputPassword extends=panelGroup element renderId=0 jsfid=outputLabel attributes set name=for value=password / set name=value value=Password / /attributes /element element renderId=1 jsfid=inputSecret attributes set name=id value=password / set name=value value=[EMAIL PROTECTED] / set name=size value=15 / set name=maxlength value=15 / set name=required value=true / /attributes /element element renderId=2 jsfid=inputSecret attributes set name=id value=password2 / set name=size value=15 / set name=maxlength value=15 / set name=required value=true / /attributes validator jsfid=t:validateEqual attributes set name=for value=password / /attributes /validator /element /component What am I missing?

Hi,
We are trying to implement uploading file via struts framework using
form bean. According to our requirement we have two scenarios' in which
we require uploading of our file.
1) Uploading single file (single html:file control and a single
upload button in jsp page)
2) Uploading multiple files (Multiple html:file controls on the
screen on the same form).
The problem is that these number of html:file controls on the screen is
not fixed, it is dynamic. The user can click on an Add More button to
increase dynamically the number of files he/she wants to upload.
We have implemented the first scenario by using html:file tag on the JSP
and keeping a form bean with html control as one of its member
variables. In the action class we extract the value from the bean and
then upload the file using I/O streams.
Now, for the second scenario we need to upload an indeterminate
(determined at run time) number of files but at the same time the number
of members in the bean class cannot be changed dynamically.
So we either need a way to add members to a form bean dynamically or
some other mechanism which will handle this multiple upload requirement.

how can I mak the list of FormFile in the form bean I tried implementing it but
got an exception of type mismatch
I did somthin lik this
private FormFile theFiles[];
public FormFile[] getTheFiles() {
return theFiles;
}
/**
* @param theFiles The FormFile to set.
*/
public void setTheFiles(FormFile[] theFiles) {
this.theFiles = theFiles;
}
how can I do it
plz reply soon, waiting..

RE: Passing Parameters to ActionForward from Action
Hi Gunduz,
At first place having to much session information using session.setAttribute
will make the middleware to consume lot of memory. And, In an application
where there will be more users who could be online at the same point of
time. It is design constraint not to put lot of information in session.
So, This can be done only by passing parameters to the page. But, I couldn't
understand (came across) how to pass parameters to a jsp from Action. If you
came across anything about how to pass parameters to a jsp page let me know.
Thanks you very much,
Siva

I am new to struts, there might be better ways to make this work.
You can maintain state information with session registery or http
parameters..
A working example:
struts-config.xml

AW: Re: [Shale] Property in ViewController Backing Bean is null
Hi Jason, I'm a real newbie to JSF and Shale, but maybe the tip that Craig gave me about setting the immediate flag in the commandbutton could help you. Then validation is skipped, as far as I understood it. This helped me with my first problem. Maybe you can use it, too. Then you could remove the H. :) Greetings, Peter I think you may running into a simular problem that I ran into. I have the following scenario: page 1 has the user choose from a list of options. On page 2, the form saves the selected option of page 1 in a hidden field in its form. In addition the selected value from page 1 is used to populate a pull down on page 2. So the user hits the submit button on page 2 to save the changes and KA-BLAMMO, I get a NPE. What was happening was the JSF was attempting to Validate the pulldown values in the Validation phase. This was before any of the hidden fields were set. So because the hidden fields weren't set, the retrieve of the pulldown was failing. I saw 1 of 2 solutions: 1) Turn off the validation of the pulldown. Because, hey... why would I need to validate a pulldown? - it isn't like a user can mistype something. OR 2) somehow get the hidden fields to be set before any retrieval of the pulldown is made. The JSF mailing list from Sun gave no help for turning off the validator for the pulldown. So I had to do the following, for which I give myself a big Capital H for HACK. In the contructor of the backing bean, I grabbed the request parameters myself and called the setters from there for the values that were needed to get through the validation of the pulldown. Perhaps someone here can help turn off the need to retrieve the pulldown values in the validation phase. I hope this will help your situation, as well.

Shall I send some code to illustrate the problem or is it really so unusual, what I'm trying to do? Make sure that you have a navigation rule setup to handle the immediate command button. Try adding a rule that directs you to the target viewid (sounds like the page you are submitting from). If you don't have a navigation case, I think the veiw is just restored using the submitted values. navigation-rule from-view-id/somepage.jsp/from-view-id navigation-case from-outcomeedit/from-outcome to-view-id/somepage.jsp/to-view-id /navigation-case /navigation-rule Thanks a lot for any help!

Thank you very much! Until then my action methods were void, because I didn't know that you have to have navigation to get the jsf reloaded complete. I thought Well, it's being reloaded, so everythings all right. I will try this further tonight at home, but I think that was the missing link for me to get really startet with Shale. Thanks a lot and keep up the good work here, I really start to like Shale. Peter - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
