Re: Forcing all @If to evaluate to True on Form Submit

Javascript runs on the client browser, the @If is evaluated on the server What are you trying to accomplish ?!?!?!?!? -Original Message- From: Karthik N [mailto:[EMAIL PROTECTED] Sent: Freitag, 4.

Re: Forcing all @If to evaluate to True on Form Submit
Bear with me it's a long description I want to use Dojo's TabContainer. But I want to implement lazy tab loading. by that I mean that all contents of all tabs will not be loaded. Here is the approach I follow: 1) I have two forms. The first Form encompasses the TabContainer and has a Submit button to save all details for all tabs 2) The Second Form has one AjaxSubmit button, for each Tab. The responsibility of the Ajax submit button is to update the Tab it corresponds to in Form 1. Hence the updateComponents of each AjaxSubmit button corresponds to each div tag for each Tab. Of course I make all this invisible so the user doesn't see it. 3) I use dojo's event system to intercept tab.show and fire off an ajax submit via a javascript click on the corresponding AjaxSubmit button for Form 2. Tacos updateComponents takes care of partial refresh of only that Tab. 4) Why do I have two forms? I want to avoid the Rewind cycle for Form 1. So a Form 2 submit will not cause Form 1 data to rewind. That way dirty Form 1 Data will not make its way to the server. 5) Why do I need @If - I use an @If to stifle the render - so if I am refreshing Tab 3, the @If for Tab 1, Tab 2 etc. will be False. That way I make the render also lazy, or rather selective 6) Why do I need all @If to be true finally? When I submit Form 1, I want the complete Rewind Cycle to kick in for the entire Form, so that all properties are set On 8/4/06, Jesse Kuhnert [EMAIL PROTECTED] wrote: Perhaps we could be more helpful if you told us what the general purpose of your logic is?

Re: Forcing all @If to evaluate to True on Form Submit
Yes I meant changing the values of the hidden @If from 'F' to 'T' - rather ugly.

Re: Forcing all @If to evaluate to True on Form Submit
But still more efficient than TRUE/FALSE for rendering. They aren't typically (hidden input fields) meant to be human friendly so I appreciate the length of statements.

Re: Forcing all @If to evaluate to True on Form Submit
Actually, the idea of Tapestry providing additional js functions that would interact with the html it renders is pretty interesting. Another (more usual) example of this is for replacing (or even including) direct link parameters on the client by tweeking the generated urls. I guess you could log a JIRA request for something like this... Karthik N wrote: Yes I meant changing the values of the hidden @If from 'F' to 'T' - rather ugly.

Re: Forcing all @If to evaluate to True on Form Submit
By ugly I was alluding to my approach, and not the formatting of the hidden fields. :-) I would ideally like not to manipulate the html using js to set a F to T, even if i know i can do it.
