What can I do ? I am a beginner !!!

[Fabiano Choueiri <fa...@camara.gov.br>]

 
        Hello, please I need some help here.
        It seems to be very simple but I can't find any explanation.
        This is the problem :
                When I put the @Checkbox after the three @ImageSubmits
Tapestry is ignoring if I check or uncheck it the first time I use it.
                If I put the @Checkbox before the the three
@ImageSubmits the things go right.
 
        What is happening ?
    
        Thanks for all help.        
 
 
 
HTML template 

<form jwcid="@Form">

    <input jwcid="codigo"  size="2" maxlength="2" />

    <span jwcid="@ImageSubmit" image="ognl:assets.imgSalvar"
listener="ognl:listeners.salvar" />
    <span jwcid="@ImageSubmit" image="ognl:assets.imgExcluir"
listener="ognl:listeners.excluir" />
    <span jwcid="@ImageSubmit" image="ognl:assets.imgCancelar"
listener="ognl:listeners.cancelar" />

    <span jwcid="@Checkbox" selected="ognl:myCheckbox"/>

</form>

If you are using T4 beta 8, please replace the 'listener' parameter of 
the ImageSubmits with 'action'.
For example:

<span jwcid="@ImageSubmit" image="ognl:assets.imgSalvar"
action="ognl:listeners.salvar" />

'listener' is executed immediately when the Submit is reached. Thus the checkbox component will not be invoked if it is located after the Submit.

'action' on the other hand is executed only after all of the components in the form are rewinded (a.k.a. a delayed listener). Thus the checkbox component will be invoked and will work no matter where it is located.
