RE: How Can I Implement a Dynamic Table?
Thanks, this a nice workaround I mean to put component.setvisible(false) depending of some parameters value. the only not convenient thing is, I belevie, that the application load anyway a lot of useless data from database. In reality I think that in the future ListView component should be just a little bit more flexible Thanks a lot indeed Andrea -Original Message- From: Peter Thomas [mailto:[EMAIL PROTECTED] Sent: 10 August 2007 15:23 To: users@wicket.apache.org Subject: Re: How Can I Implement a Dynamic Table?

RE: How Can I Implement a Dynamic Table?
Normally you put in the wicket:id of the listview component and in the single component previously added in the listview How could you manage that with two listview in the manner you indicate?? Have you ever tried that? are you sure? Anyway I guess the problem of the match between components in form object and markup do not change when you create a list view implicit you define a fix number of columns thet you add to the listview which in turn you add to the form. Please, if you can, post the code you used to solve the problem or try to sketch it. thanks -Original Message- From: Paolo Di Tommaso [mailto:[EMAIL PROTECTED] Sent: 10 August 2007 14:41 To: users@wicket.apache.org Subject: Re: How Can I Implement a Dynamic Table? There are many ways .. For example you can have two nested ListView, for example: value The first iterate over the row as usual, and the second over the columns. The problem can be reduced to have a valid model to specify the columns. This could be done, with a simple array of bean attribute names or using reflection to extract bean getter ... or some other complex way .. - Paolo (at fao.org) On 8/10/07, Pantaleoni, Andrea (KCTU) <[EMAIL PROTECTED]> wrote: > > Hello, > I have to implement a dynamic table: depending on user choices or values > of > fields in database, the number of columns could change. > e.g. In same case I can have 3 columns containing Labels or in other cases > 5 > containing Labels and form components(and so on). > To do that I'm using a ListView inside a WebMarkupContainer(I need to > implements some ajax behavior too) > The problems is that wicket require a exact match between components added > to > the form object or page and markup items inside the relative html page > Someone of you has already faced that problems? > Any suggestion? > > Many Thanks > Andrea > > - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: getting component parent
Actually I'm using use 1.2 -Original Message- From: Will Jaynes [mailto:[EMAIL PROTECTED] Sent: 10 August 2007 13:52 To: users@wicket.apache.org Subject: getting component parent Using 1.3. I have a panel which needs to create different internal components depending on who it's parent is. However, calling getParent() in the constructor gives me null. I can make a constuctor that passes in the parent. But I wonder if there is a different way. Is there some other point where I could call getParent(), get the parent, and then construct the components for the panel?

How Can I Implement a Dynamic Table?
Hello, I have to implement a dynamic table: depending on user choices or values of fields in database, the number of columns could change. e.g. In same case I can have 3 columns containing Labels or in other cases 5 containing Labels and form components(and so on). To do that I'm using a ListView inside a WebMarkupContainer(I need to implements some ajax behavior too) The problems is that wicket require a exact match between components added to the form object or page and markup items inside the relative html page Someone of you has already faced that problems? Any suggestion? Many Thanks Andrea
