Problem updating a column using datatable
I have a table that displays all rows as readonly. If the user clicks on the
edit button on the side, then that column is no longer readonly and they can
update the value. However when the instance gets back to the backing bean
the data for columns that were originaly readonly has not been updated. Any
idea? In the example below, only one column is read only at first. When
they click on edit, I update the column but the new data never gets back to
the backing bean. If I remove the readonly clause it works, however all the
rows are now editable. We can only permit one row to be edited at a time
because of special validations that need to be done.

Re: Problem updating a column using datatable
Posted by David Delbecq <de...@oma.be>.
Hello,
Check that
readonly="#{!(disability.id == null or
(disabilityDetail.isEditableRow and disability.id ==
disabilityDetail.instanceParamId))}"
is true, not only at render time, but also, after submission of new
value by user, at processValidation phase. If it's false at render time,
html edit box will be readonly. If it's false at processValidation time,
even if it was true at previous render, the submitted value will be
ignored by component.
regards,
David Delbecq
