Subject Re: [jira] Created: (TAPESTRY-634) Cannot dynamically set the id for a Form
Date Fri, 09 Sep 2005 19:02:35 GMT
Part of the value of Tapestry is that it assigns ids.  The id of the
form will *likely* be the same as the component id of the Form. 
However, inside loops (or when using Tapestry to develop portals) the
id will vary from what you specify (to ensure uniqueness).  That's why
Tapestry has the JavaScript templates (the .script files) to create
JavaScript customized to the ids allocated by Tapestry for forms and
form fields.

> Justin's (who is a coworker of mine) real goal in that case was to be able to dynamically
create an id for a form.  We use that id for javascript functions and bug testing.  His issue
was that the framework was generating an ID as well and both were being written as attributes
in the html.  Howard's solution was to disallow informal id tags for Form components by making
"id" a reserved parameter.  I think what we were hoping for was for the framework to not write
a generated id if we specify one, so that the FormSupportImpl's render method would look like:
