Re: [SunONE-JATO] Re: How to use a tiled view without a model

Question

I'm not sure what is different for you now. You still parse the string
and put it into a data structure. Before the data structure was a
vector, in JATO its just a model with a "hidden" data structure (a hash
map).
MVC only really comes into play when you talk about where your write
this code, and where the data structure is being stored. So really, JATO
takes care of half of the MVC'ness of it all (where the data is store).
You just decide where to be the code to populate the model.
Make sense?
Is there something different required of you in JATO in this scenario
that I am not grasping?

Thanks for the feedback.
The problem I was solving involved a single string, which contained
delimited subsets of information.
The string looked like
this:"time|analyst|description|time|analyst|description|..."
In ND, I parsed it apart into it's components (time vector, analyst vector,
description vector), populated the repeated.
With JATO, how would I make a model for something that doesn't have a
database component like this?
I'm pretty new to this MVC thing, so bear with me.

I guess the only thing "weird" (for lack of a better term) about what
you are doing is that your are populating the model on the "display
cycle". Typically, the cycle goes like this:
Request -> populate model -> update data store -> retrieve data to
populate model -> display data
some of the above steps are optional but hopefully you get the point I
am making.
So what you are doing is:
Request -> populate model/display data
If it works for you, then it's not necessarilly wrong. But I would
probably have my model populated before I forwarded to the target
(displaying view bean) or at a minimum, in the begin display event of
the view bean or the tiled view, but not during the iteration of the
tiled view.

Craig,
Thanks for the pointers. I ended up doing something else. I set the
models setSize() method to set the max size, and as the tiles fields
iterated, populated the value from some vectors I had the data in
already. Is this solution fraught with peril and will ultimately fail,
or should I try your way?

John,
Check out the docs for DefaultModel. There is an appendRow() method.
So get your tiledview's primary model (the tiledview's primary model
should be set to use an instance of DefaultModel), model.appendRow(),
then model.setValue("fieldname", value) for each value.
Rinse, repeat as needed.

setMaxDisplayTiles() in the beginDisplay, but it won't get down and
generate the rows.
