How to dynamically show different components for each row in a table

[kevin_zhai <ja...@gmail.com>]

I have a  Table that has a column containing buttons for operations on each
row. Each row may have different operations applicable to it, so the buttons
for each row need to be determined dynamically based on the contents of row.

I have seen code to dynamically create buttons, but what I would like to
know is how to do this on a per-row basis, so that row 1 would might have 1
button, row 2 would have 3 buttons and so on. I would like to avoid the
solution of creating all of the possible types of buttons and hiding the
ones that do not apply to the current row.

This is probably best discussed on the users list.  The dev list is
for discussion of new components and general project coordination.

Re: How to dynamically show different components for each row in a table

I had a similar problem where I wanted to display different UI input
components depending on the type of data in the row (ie String, Date, Double
etc). I found the easiest way to do this was to add ALL the options and
select which is displayed using the rendered attribute. I also did not want
to just 'hide' the ones that did not apply, however as far as I know the
rendered attribute doesn't just hide the component, it doesn't even create
it. I needed this behaviour otherwise I would have got runtime errors eg
trying to call a String method on a Double.
Hope this helps,
Nick
