I�m having problems trying to render a selectManyCheckbox from inside dataTable.
After a db query I have a Collection of objects wich I render using dataTable, as follows:

With this requirenment in mind I�ve been trying to render a selectManyCheckbos given to each one the pk value from the list... it�s not working...

follows the code I�m trying to use:

any help will be appreciated.... tx in advance...

Hi Marcos,

I was trying to do that same thing a few weeks ago. With the help of some old topics, ranchers and Google, I found out that selectManyCheckbox is not such a good choice. From what I see, you want to select some 'linhaSistema' objects, right? The approach that worked for me was to add a selected (boolean) property to 'linhaSistema' and use selectBooleanCheckbox. Then you iterate over the collection again to check which objects were selected when the page is submited. Regards,

Its right to say that we can use <h:selectBooleanCheckbox />
But i am having the problem that how to generate dynamic ids for every checkbox, bacause it should be there so that we can easily differentiate that which checkbox is selected.

About checkboxes in datatables, here is a useful reference: Using datatablesSelect multiple rows.

Bauke's solution worked for me. I used h:selectManyCheckbox.
I agree. Here's the link:
