Dear fellas,

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?

Cheers

Hi Harry,


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.


Regards,


Jason,

Shooting from the hip: A classic mistake is having no read statement in the Read trigger...

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? 

retrieve/e "bla"

if ($procError < 0)

message/error "%%$procErrorContext%%%, %%$dataErrorContext%%%"

endif

if ($status = -2)

message/hint "no hits found"

endif

Cheers
