Re: JSF/EGL datatable positioning question

["Aaron Bartell" <albartell@xxxxxxxxx>]

So Tim, to answer your question based on Joe's response I would simply
create a state saving variable (i.e. firstResult) that maps to the "first"
attribute of the dataTable tag.  And then for each request you can alter it
to meet your need.  

Note that depending on the type of form submission, you may want to reset it
to it's initial value (i.e. 1).  For example, if the list is based on a
search you would want to reset to firstResult=1 in that case.  I got bit by
this awhile back because a search obviously has the ability to return a
small subset of records and if the value of firstResult is beyond that of
the actual results then you will see a blank dataTable list.

Does that answer your question Tim?

HTH,

The only difference between what you're writing and what EGL creates is the
fact that EGL uses the Extended Data Table from IBM's Java Widget Library.
The tag (hx:dataTableEx) has a first attribute, which, while I haven't used
it, should do the same thing the first attribute does for x:dataTable.

Here's documentation on the dataTableEx tag:
