Disable Auto Shipping Update in Magento Admin - magento-1.4

If you've used the Magento admin, then you know that when you tab between the "Shipping Address" order screen it's kind of buggy. It does an AJAX call behind the scenes anytime that any field is updated. This keeps the shipping up to date, but its very annoying when trying to key in orders. Does anyone know a good way to disable this automatic functionality, so that it could be done with a button, instead of happen "automagically"?

I can't point to anything specific at the code level, as I don't have the code handy to look at just now, but I know it won't be easy per-se.
You will need to find and rewrite (unless it's all in the templates, then you'll need a custom admin theme) the block which generates that form, strip out the calls which add the handlers to the onblur events. Theoretically, your button should be able to call the same JavaScript method which is called via the onblur of the form elements.

f.select - disabling option based on the first one selected in Rails

I have a form in which user can select two players from a list (two separate select fields). I managed to do it using options_for_select helper, but
user shouldn’t be allowed to select the same player twice - it obviously can't be something like player1 vs player1. I was experimenting with ‘disabled’ option, but without success, because list of available users should change dynamically after selecting first user, which probably can't be done in Rails?
This is a very broad question, with little details, hence my answer will be generic to cover the majority of cases.
You'll have to use JavaScript to hide the same options from the other list. Rails works server-side, therefore you should reload the page if you want Rails to re-render the list without the selected option. But this is a terrible user experience.
However, you should also perform a server-side check. Even if you add the JS in place, it will still be possible to send a crafted request where the players are the same. This is something that must ultimately be verified at server-side level, in your Rails controller or wherever you have the logic to handle the comparison.

Validation error messages disappear when Trinidad component panelAccordion is minimized or maximized

I have a form that is very long but is submitted and validated all together. I need to break it up into sections.
I have tried using the Trinidad component panelAccordion to break the form into sections.
However if I then submit and validate the form, clicking one of the panels open or closed causes the validation messages to disappear.
Is there any way to avoid this?
Or is there a better way to achieve the same result of breaking up the form?
I am using Trinidad 1.2.6 and MyFaces 2.0.
Due to corporate standards I cannot use anything else.
One way you can achieve the desired effect is by submitting the form when a user clicks on each <tr:accordionPanel>. It supports many other client side events so pick one that best suits your needs.If you submit the entire form, this will force validation to kick in for all components however, whether the user entered a value or not. This might be the quickest and simplest way but some people might be picky and not like this solution.
You can also make use of partial updates and partial triggers and submit only the components that are part of the current accordion panel based on the event you choose.

Concept for a grails app

I am working on a Grails project, its an accounting project. We have multiple clients and they can have multiple types of accounts. I have to create the 'create' page for client, there should be a way to add multiple types of account to the client.
So I was thinking of making a drop-down list with account types and few text boxes to enter account name and other info about account. Also, as a client can have multiple accounts, so I want to create a 'add' button, when clicked it would display a new row to add a new client. I have done this kind of UI before using javascript but in this case, as there is a drop-down list and other components, I think it would be very hard and may not work.
I was thinking of creating a partial view which would render each time user clicked the 'add' button with additional row, problem with this would be during validation errors, edit page and i would also have to pass all values each time user clicks 'add' button.
Is there any other for doing this?
For the template approach you must use ajax if you don't want to carry on the params that the user has already set.
It is possible to make new drop-down lists appear (or any group of elements inside a <div>) when a user clicks a button, since Grails already comes with jQuery you might want to take a look at the .clone() method.
The problem with the two listed approeaches is that it will be possible to have duplicates.
Now, another option is to use checkboxes, so you can check just the type of account you want.
But to be honest it does seems a bit odd or even inapropiate to let the user choose the type of account he wants with such freedom.

Make checkbox as a link?

I want the html.checkbox() in ASP.NET MVC to be as a link that goes to an action controller (GET and not POST).
Question:
It is possible to make the html.checkbox() to act as a "actionlink" instead of going to the FormCollection without using Javascript and JQuery or any additional plugin?
This wouldn't be possible in any framework as checkboxes are just static input elements. They have no ability to trigger any sort of action on their own, hence where javascript and event handlers comes in.
You could try making a form who's method is GET, but it would still have to go somewhere.. I guess you could make an action that handles various states of a checkbox and then routes to the correct page, however you'd still need to submit this form by having the user click a submit (again because the only way to trigger an action from clicking a checkbox is by using javascript)
You could also fake a checkbox using css and checkbox-like images.
text goes here
If you need to show it as either checked or unchecked, you would use two classes with two different checkbox-like images.
I doubt this is possible without javascript.
Except for buttons and links, no controls actually do anything but change their own value in the DOM.
It would however be rather trivial to add an onclick to your checkbox that would do whatever (including a GET request).

How to have previous and next button in the django admin (change_form)

I want to modify the django admin for a particular model to provide the following behaviour.
A user make a search on the change_list page. The the user click a specific entry and he lands on the change_form for that entry. Nothing different to the usual.
Now, what I want is a mean to navigate the former search results. Basically next and previous buttons on the edit page.
What would be the best approach to implement this feature without modifying the admin site too much?
I will need to memorize the search in the user session, then when an entry is clicked I will need to known which place it has within the results to place my "cursor" accordingly. But I'm a bit in the cloud as the implementation side.
One way is to just put the next and previous button in the template for that particular model.
This can be implemented using simple javascript.
I ended writing a fully custom admin for that.
