The most common cause of this is from what is termed 'auto-detection'
in ooDialog. A feature that I very much dislike. Read about it in
the Dialog Object chapter -> Data Attribute Methods -> Understanding
Data Attributes.
Basically what is probably happening is this: auto detection is on by
default. After initDialog() finishes, automatic data detection sets
the "value" of each control to its auto "detected" value.
Since you probably don't know about auto detection, you probably
haven't changed the value of the edit control's data attribute, and so
it gets set to blank text, after you used setText() on it.
I would advise every one to not use this feature, but once you
understand it, it might have some value for some people.
The easiest thing to do, is to turn auto detection off, in my opinion.
You can do that one of 2 ways.
1.) Use the .application object to set the default to off, rather
than on. Normally you would do this at the beginning of your program.
Add this line as the first line in your program:
.application~autoDetection(.false)
The first argument actually is optional and defaults to .false, so
this is the same thing:
.application~autoDetection
2.) Over-ride the initAutoDetection method in your dialog class. Add
this method anywhere in your dialog class
::method initAutoDetection
self~noAutoDetection
Of course, if this is not the cause of your problem I would need to
see more code. But, it is most likely what is happening.

You can control this through the Edit class. Use the setLimit()
method of the edit control. The argument to the method sets the
maximum number of characters that can be entered by the user in the
edit control.
Read about the setLimit() method in the reference at Edit Control -> setLimit
You can read more about the .application object at Utility Classes and
Objects -> .application object and also at Utility Classes and Objects
-> ApplicationManager Class. The .application object is an instance
of the ApplicationManager.
And data attributes and things related to them are explained in The
Dialog Object -> Data Attribute Methods chapter.
