Multiple row selection

[trouby]

Hey,

I have created a CRUD actions for a specific entity via Seam-Gen which seems to be nice and clean using EntityHome/EntityQuery,

I would like to add to the generated list another column that has a boolean jsf tag in order to support multiple row selection,


I thought about adding a map to the EntityQuery seam component such as:

Map<MyEntity, Boolean> rowSelection;

and in my facelets code (per row):

datatable...
<column>
<h:selectBooleanCheckbox value="#{myEntityList.rowSelection[myVarOfDataTable]}" />
</column>

I was wondering if there's a better way to pass the selected rows to an java action since this way is a little bit annoying due to the fact that -all- rows are passed but only the selected entities are equal to true,
so iteration + if conditions is required, etc...



Thanks,

Asaf.

Perhaps you could try writing an EL function that takes your Map and returns a list of only the selected items?

Ye I know, that is only for facelets, just wanted to avoid constructing the map for all of these objects that were not selected,


but I'll wrap the map with a method that creates a list of the selected objects only,


thanks
