This is my first week get in touch with Uniface9. I'm trying to go through the exercise materials in u9FoundationExercise.
I don't know for some reason, I followed Excercise 16 Part 1 - Sequence, I can't retrieve any data into my form.
Can anybody help me?
The question what is the name of the entity? Use for example retrieve/e "yourentname". Is that entity painted? if yes, is that entity a database entity? if yes, has the read trigger a read statement? if yes, is there a database connection...that easy to test $procError, $procErrorContext, $dataError, $dataErrorContext contains values when it go's wrong....with other words, does the used retrieve profile deliver hits?
if ($procError < 0)
message/error "%%$procErrorContext%%%, %%$dataErrorContext%%%"
if ($status = -2)
message/hint "no hits found"
Shooting from the hip: A classic mistake is having no read statement in the Read trigger...
Put a debug statement line before the retrieve, compile, test and step through the code. See what $status and $procerror tell you. I realise you are new and may not have used the debugger yet, however it is relatively straightforward to use.
Does the message frame (GOLD-M) have any messages?
Here is the material
