i have a form with 2 buttons let say A & B.
The required fields are depending on the button pressed.
Im using actually a DataBinder allowing me to specify requiredFields but for all actions.
How can i customize the required fields that will be depending on the button pressed ?
Thanks in advance
If you use <input type="submit" name="button1" value="Click me!" /> you can check for that button1 value in your form and then use different validation rules within your validator. You just have to extend your binding model according to these button names and to give your two buttons different names. Note that this doesn't work with <button type="submit"> in most IE versions and therefor input[type=submit] is the better choice here :-)

I am facing an issue that is really hard to debug. I have a JSP page that has some form elements on it that submit to a Struts2 action. I also have a XML form validation file to perform some validation on the submitted fields. The file has the naming convention 'actionName-validation.xml'
This works fine, but when I add a drop down box, outside of the form, the validation now fails. Instead it redirects to a blank page and my breakpoint in my action class is not hit.
Is there a way to turn on some kind of debugging or logging for the validation? Why would adding a tag outside of a form cause this to happen?
Here is the code on the JSP page:
<s:select id="dataSource" name="selectedDataSource" theme="simple" listValue="top"
headerKey="" headerValue="Choose Data" list="dataSources" size="1" />
<div id="forms">
<s:form method="post" action="MyAction" theme="simple">
<p>
<label class="input" for="name"
<span style="color:red;">*</span>
<span>Name</span><br>
<s:textfield theme="simple" name="name" maxlength="11" size="11" />
<br>
<s:fielderror theme="plain"><s:param value="'name'" /</s:fielderror></label>
</p>
<s:submit value="Create New" theme="simple" cssStyle="display: block; clear: left;"/>
</s:form>
</div>
If I remove the <s:select> tag, it works.
Any help would be greatly appreciated it.
EDIT2: I found the problem. I needed a get method for the list that is used to populate the select drop down inside the action that the form submits to.
I had one for the action that initially is called for the page, but when the validation fails and it re-loads that page from the form action class, it tries to re-populate the select drop down and needs a getter there. I feel silly for not finding that sooner. Would be nice if there were some type of logging or messaging of these types of issues.
thanks.
The error you are encountering is not a validation error (handled by the Validation Interceptor), but an error occurred when setting the parameters (raised by the Parameters Interceptor) and for which the Conversion Error Interceptor added a fieldError, which you are not seeing because
your INPUT result lands on a blank page and
you are using theme="simple" on the textfield, which forces you to add <s:fielderror fieldName="dataSource" /> to show it (or <s:fielderror /> to show them all).
Read how the INPUT result works, set your page as the INPUT page, print the errors, then you will discover the problem, that is most likely related to the fact that you've not specified a listKey attribute in your select, that is sending the description instead of the code of the datasource to selectedDataSource, which is probably an Integer.

I'm trying to cover my project with test and faced with problem.
The "press" method of TestCase fails with 'InvalidArgumentException: Unreachable field ""'
However the "see" method sees the needed button
Besides another form on another page tests fine
Hours of debug show me that the issue might be in the fact that the problem form has multiple (with this brackets []) inputs
Test code that fails
$this->type($params['from'], 'from[]');
$this->type($params['event'], 'event[]');
$this->type($params['class'], 'class[]');
$this->type($params['method'], 'method[]');
$this->press('save_handlers');
With form and button everythings is okey
Button:
<button type="submit" class="btn btn-primary btn-block" name="save_handlers">Save</button>
And of course button is in the form tag
Indeed, the problem is linked with the fact that there are attributes with brackets[].
I just had the same problem. I'm using a form with multiple checkboxes, and all of them have the same name (but different id) : codes[]. I'm doing this in order to retrieve them later (in a controller) simply as an array of values.
<input id="perm-0" type="checkbox" name="codes[]" value="perm-0" />
<input id="perm-1" type="checkbox" name="codes[]" value="perm-1" />
<input id="perm-2" type="checkbox" name="codes[]" value="perm-2" />
My friend var_dump() told me that the Symfony component which parses the form inputs doesn't like it when I'm using codes[] with nothing inside the brackets. It is seen as two fields : "codes" and "" instead of codes[]. That's causing the Unreachable field "" error.
A simple solution I found is to simply add an explicit index for the codes[] array :
<input id="perm-0" type="checkbox" name="codes[0]" value="perm-0" />
<input id="perm-1" type="checkbox" name="codes[1]" value="perm-1" />
<input id="perm-2" type="checkbox" name="codes[2]" value="perm-2" />
This way each checkbox is distinct from others, and the method press() does not cause the error any more.
It seems that this doesn't affect the processing of the resulting array in my controller.
This seems rather confusing seeing as the docs state this:
"Press" a button with the given text or name.
While the docblock above the actual press method states the following:
Submit a form using the button with the given text value.
So instead of using the value of the name attribute (save_handler) use the actual text (Save).
$this->press('Save');
I wanted to ask just what title says:
say we have a inputtext and a button. Well, I wanted to submit an ajax request in the inputtext when button is clicked.
for example, from the inputtext perspective, I want to achive something like this:
<h:inputtext>
<a4j:support event="button.onclick"/>
<h:inputtext>
<h:button id="button">
or, from the button perspective:
<h:inputtext id="input"/>
<h:button id="button">
<a4j:support event="onclick" action="input.submit"/>
</h:button>
Don't know if there exist an easy way to get this done.
thanks in advance!!
If you just want a simple form submit, I think both approach are wrong, as long as you put your inputtext and button properly in a form, the form will automatically submit whatever you have in this form including user's input in inputtext when you click the button. There is no need to do something like input.submit yourself. (and it's not correct, either)
For the following case, you will see the setInputValue() of managed bean being invoked when you click your button.
<h:inputtext id="input" value=#{bean.inputValue}/>
public void setInputValue(String inputValue){
this.inputValue = inputValue;
}
Try using
Richfaces Region component to limit your request to diffrent regions.

I finally get this done by means of <a4j:jsFunction>

please tell me where the actions in a joomla 2.5 controller written. in joomla 1.5 i remember we use to write the actions like add, edit, remove, cancel etc in the only controller. but i am puzzled in joomla 2.5 because i find three controller even for helloworld component. and i also don't find the functions for actions defined in the controller. i saw only display function in the main controller.
then i also wanna know how each JToolbar button is mapped to an action in the controller.
First of all those methods are not shows in the controller that means its in library section.
For your requirement you can create new or same methods in any of the controller If you use same methods like save(), delete() cancel() etc its will override the Joomla's default functions.
In your toolbar section you can have mention the function name as well.
JToolBarHelper::title('Yor custom component', 'head vmicon48'); //set title
JToolBarHelper::apply('saveConfig'); //when the apply button click its will call the saveConfig function the controller.
JToolBarHelper::cancel();
For some toolbar button argument order may different you can find here.
Also if you have more than one controller from your form you can mention the controller like as follows.
<input type="hidden" name="option" value="com_helloworld" />
<input type="hidden" name="view" value="yourview" />
<input type="hidden" name="task" value="my_controller_fun" />
<input type="hidden" value="your_controller_file_name" name="controller">
Hope you will get some idea !
I am using the MvcContrib Grid to display a table on the page. I am using a custom column to produce a checkbox on the table so that the user can select multiple rows and submit the form.
I don't want the form to submit unless at least one checkbox has been selected. I could easily write this Javascript myself to enforce the validation, but I wanted to know how I could fit it in with the unobtrusive library supplied with MVC3.
I imagine I just need to set my inputs with the proper classes and attributes and then the scripts (validate and validate.unobtrusive) on the page should pick them up and mark them as needing validation, but I haven't been able to get the right combination thus far.
Here is the input that I am currently generating:
<input type="checkbox"
name="foo"
value="#item.foo"
class="input-validation-error"
data-val-required="Please select an option."
data-val="true" />
Try setting the data-val attributes on the item, then you have to tell jQuery you have new content to re-parse the form via something like:
$.validator.unobtrusive.parse($('#yourForm'));
where form is of course a reference to your form element.
There is also this great posting and jQuery has a few internal adapters you can call:
from http://www.devtrends.co.uk/blog/the-complete-guide-to-validation-in-asp.net-mvc-3-part-2
jQuery.validator.unobtrusive.adapters.addSingleVal("notequalto", "otherproperty", "mynotequaltofunction")
From my experience, a commonly overlooked mistake with displaying client-side validation is putting a Html.ValidationMessageFor(lambda) on the page.
Without that, no client-side validation will fire to prevent the form submit and/or display the message that is generated using annotations on the client-side.
Hope this helps.
<div class="editor-field">
<input class="text-box single-line"
data-val="true" data-val-number="The field Qty Available must be a number."
data-val-range="The field Qty Available must be between 0 and 120."
data-val-range-max="120" data-val-range-min="0"
data-val-required="The Qty Available field is required."
id="QtyOnHand" name="QtyOnHand" type="text" value="12" />
<span class="field-validation-valid" data-valmsg-for="QtyOnHand"
data-valmsg-replace="true"></span>
</div>
The tie-in between the data model annotations and the data-val-* attributes should be clear after reading the above code, but it's where the client side validation ties in might not be so obvious. Open the \Scripts\jquery.validate.unobtrusive.js file and search for "data-val". Right away you'll see that the JavaScript uses the data-val-, input- and field-* CSS classes to display/hide validation messages on the client.
