Re: Seaside+Bootstrap and callbacks

The #callback: as you're using it in the button doesn't render HTML to the
page. It just tells seaside to change something in the image and then
re-render. 

Because of that your #action: method, if it ran, wouldn't change the page.  

When Seaside re-renders your app, depending on what you do in the callback,
it might re-render the page with some changes or another page.

It looks like you want to open a modal over the current page when the button
is clicked.  Right? 

If so, two ways that come to mind to do that are to either, after the button
is clicked,

 - re-draw the page with the modal dialog HTML code rendered in it and set
to open on load,

or 

 - load the modal dialog HTML code into the existing page with
Javascript/Ajax and open the modal.



The first way:

MyBootstrap>>initialize.

super initialize.
showModal:=false.

MyBootstrap>>renderContentOn: html
self renderMyButton: html
self renderMyModal: html.

MyBootstrap>>renderMyButton: html
html anchor 
class:'btn btn-primary';
callback: [self showModal];
with: 'Show modal'.

html anchor 
class:'btn btn-default';
callback: [self hideModal];
with: 'Hide modal'.

MyBootstrap>>showModal
showModal := true.

MyBootstrap>>hideModal
showModal := false.

My Bootstrap>>renderMyModal: html
showModal ifTrue:[
 html tbsModal 
     id: 'myModal'; 
     attributeAt: 'data-show' put: true; "<--- opens the modal when rendered
on the new page"
     with: [ html 
              tbsModalDialog: [ html 
                      tbsModalContent: [ html 
etc, etc... 
].


Another approach could be to use jQuery to load the modal into the page and
open it when the button is clicked.  


If so I'd do it like this:


renderContentOn: html
html tbsButton
bePrimary;
onClick: ((html jQuery id: 'myModalContainer') load html:[:h | self action:
h]; onComplete:((html jQuery id: 'myModal') call: 'modal' with: 'show');
with: 'Modal'.

html div id:'myModalContainer'.



And keep your #action: method as you have it now.
