Re: EGL table questions

Joe,

For point 1, you are suggesting calling an RPG program say 20 times to get
20 records. Is that faster then passing a data structure of say 20 records?

Two EGL table questions:
1. I have an array that I am loading from an RPGLE data structure
defined with 99 elements. Is it possible to get my EGL table to only
load significant data structure rows?
2. How do I trigger an event when the user clicks a table row and
retrieve the row values?

1. I don't pass data structures arrays from EGL to RPG, I simply pass a
single data structure (a record). The RPG program returns data to me
one record at a time until no more needs to be returned. After each
call I perform an appendElement to add the record to the array. So you
can either filter the data in the RPG program and only return valid
records, or you can use extra logic in your EGL to add only those
records you deem significant.

2. It depends what you mean by "event". Do you want to go to another
page (traditional JSP Model 2 style, which includes redisplaying the
current page in its entirety) or do you simply want to refresh a portion
of the current page (Ajax style)? Both are possible with EGL, although
the latter requires a little more detail work (you have to define the
individual areas that can be updated, then define events that trigger
those updates).

The first one in particular is already available in the basic tutorial
from the Jon Sayles web site. Me, I usually just create a hyperlink to
the next page using the data in the row as a parameter.
