[Trinidad] problem with filtering a sortable table

[Gerhard Petracek <ge...@gmail.com>]

hi everybody!

is there a suggested way for filtering the data-model of a sortable table (+
ppr)?
(especially for triggering the re-indexing of the internal structures)

filtering a table works very well.
e.g. the following scenario:

there is a table and a checkbox on the same page.
the checkbox triggers (with the use of ppr) a filtering process.
this scenario works very well - the collection which is associated with a
table is filtered and redisplayed correctly.

however, after adding support for sortable columns the following problem
occurs:

sorting works well - and the internal _baseIndicesList and
_sortedIndicesList are correct (without the filtering functionality).
(to summarize: if i don't combine them, filtering and sorting work
correctly)

combining these two features causes a wrong result.
(sorting -> result is ok -> filtering -> result is wrong)

after a quick debugging session i saw, that the referenced model of the
table is ok.
however, the internal _baseIndicesList and _sortedIndicesList aren't
recalculated (they are out of sync compared to the referenced model).
so the calculation of rangeEnd results in a wrong result (e.g. 0 -> an empty
table is displayed - even though the model contains several entries)

is there a way to solve this problem without changing trinidad?

if no:
i've several ideas to solve this problem (one of them is already tested!) -
but i think this would be a topic for the dev-list.

gerhard
