T5: Removing empty valued columns from grid
Hi,
I'm looking for a piece of advice/suggestion on the best way to handle the
following.
Using Lucene i generate a searchResult list, in which each searchResult
entry contains a (Lucene)Document. These results wil be displayed in a grid.
Since i cannot determine beforehand which columns (read fields) i will be
receiving i put together my own model and conduit (as per example on the
list somewhere).
So far so good, i'm getting the results i'm looking for.
Final tweak concerns the elimination of the columns without any values.
Obviously this needs to be done prior to rendering but after the results
have been obtained.
My question is twofold:
1. Can i modify the grid model (excluding columns) after its initial
creation, and
2. If so, what would be the best place to do so?
Tia,
Fermin Da Costa Gomez

So the rendering starts where, OnPrepare or onPrepareForRender .. ?

I guess so. Makes sense to think that Grid expects to render exactly what
it received (source and model).

Hmm, mucking about in the DOM is not what i'm looking forward to ..
I my assumption correct that once the grid building has started it
*is*actually doing the rendering as such?

I guess not, but you can write a mixin to do that after the rendering,
changing the generated DOM.

We use "Obrigado desde já". :)
I didn't know that acronym. I learned something new today. :P

This i did as well.
I can get to the the model, fields etc.
The issue/challenge is the fact that only the conduit "really knows" which
fields are empty but it does its job on a per cell basis, if i'm right.
I suppose i could have a look at making sure all fields are in their final
phase before going into the conduit, but
Coming to think about it i have to rephrase my question to:
Is is possible to 'modify' the grid *after* the conduit has done its job,
ie. just prior to the actual rendering.
If a columnwas created that contained unwanted entries this would be the
only point remove whole columns ... or?

When I need to manipulate the BeanModel, I create a BeanModel
getBeanModel() method in my page class and add t:model="beanModel" in my
Grid.
