I'm sorry if this has been posted before but I cannot find the answer to this problem
in the existing messages...
I have a repeated that has fields that are bound to a dataobject. When the dataobject
select executes and no rows are retrieved I am getting a blank row in the HTML. This
behavior is explained in the documentation. However when I try to get the value of the
textfields in the onBeforeRowDisplay to skip the display of the row I am getting
results that I do not understand. I'm also using this event to gather information used
to calculate a value for a statictext that is displayed on the same row.
For the first row of the repeated my results are always blank. Not NULL, but blank.
Am I doing something wrong here. Below is a snippet of code showing what I'm doing,
The commented out code shows what I'm trying to accomplish when the row is truly
blank.
If anyone could help out with a code sample that works I would greatly appreciate it.
I've been messing with this off and on for the past week and it's really irritating me.
Thanks!
