Why won't this dataSource work?

22 February, 2008 - 02:35 — t4p

I've spent hours tweaking this thing, and searching the very few sources
of information about this, and found no help. I need to have a dataSource
in an "e:variable", so I can manipulate it (e.g. add/delete rows). But
the dummy data I've put in will NOT appear in the listGrid.

What am I doing wrong?

Source code is included, and the relevant part is commented.

Thanks,

‹ listgrid date sort c:load and b:populator ›

the element data (e:data) problem

22 February, 2008 - 15:29 — yudi

hi t4p,

I have reproduced your list grid for testing and the element data (e:data) has to have namespace with null value (xmlns="")to make it works with the list grid. After you add the namespace inside the data element, then it should work.

<e:variable name="variantsData">
     <e:data  xmlns="" type="text/xml">

Why won't this dataSource work?

Yes, it worked. Thanks for the help.

But now a serious question. Where would it have
been documented that this kludgy hack is required
to make this stuff work? Not in a million years
would I have properly *guessed* the solution to this
problem. I experience bugs like this constantly and
they sap away countless hours of frustration from my
time. These are things I consider bugs - what is up
with this?

Hi t4p,

I agree that this should have been well documented in the previous release. Actually,this is known bug in the documentation BB 4.1.2 and 4.1 and already been fixed for the next release BB 4.2. You'll find the fix in the next release Backbase reference ( data element example). We are working hard to improve the documentation for the next release. Specific suggestions are always welcome!

Cheers,

Yudi

Hi, Yudi,

The biggest need in the docs right now is an increase
in "cookbook"-style examples of getting various things
to work. Particularly, details about how dataSource
XML needs to be structured, and a generous collection
of "How do I..." snippets that are easy to navigate
and locate. The would help quite a bit.

Thanks,
