Reading from text fields
After some exercising with logging now it stop write into dcc.properties file and delete all values from it.
When I put in new values into dcc.properties directly and when I start app it prints this values well, but when I change them, file still have old values.
Everything was working like watch, what may happened.
I even come back with Subversion, but I didn't find any critical changes into the code, reload JDeveloper - nothing!

Yesterday everything work perfect. Why it stop reading?

Make sure you're reading and writing to the file think you are

What you mean? I have only one dcc.properties and whatever I write into this file directly appear on the screen.
Problem, as I see that this method

I even change dcc.p to dcc2.p and it's create exact copy of dcc
ASKER
I found that something wrong with recording.
If I delete any line from dcc.p and start app this field shows empty, but when I try to close app via Exit it shows:
When I cancel in force it delete whole content of dcc.p and next time I can't start.

Don't do that, it will cause the field to be null. If the field isn't found on load, you should initialize the text field to an empty string

I make like this
It shows settled value and save it into dcc, but if I change value, anyway it save in dcc old value.
Something wrong with reading after typing, it's read well settled in any way value: or from dcc.p or direct setting, but all typing are ignored.
resistance_EURUSD.setText("1.4280"); // Resistanse level
// resistance_EURUSD.setText(applicationProps.getProperty("eurusd_resist")); // Resistanse levelIt shows settled value and save it into dcc, but if I change value, anyway it save in dcc old value.

objects will be along later: he suggested doing this the hard way
ASKER
I'll attach now DCC.java
You have old one, please check what it maybe the difference.
But, as I told before, I check in Subversion, but I didn't find anything critical.

Yes, thank you, this is's work, but why it perfect works before with old construction and now stops?
no idea sorry, not sure what you changed before

just for understanding root of problem, what is the possible reason this break?

you were previously updating the variables that you were using
ASKER
@objects
please clarify
please clarify
previously you must have been updating the value oif the eurusd_support variable to be what was in the text field
ASKER
ok, anyway I think this way much straight and reliable.
Logging is not really connected with the problem most probably. You just need to ensure the the file saving method is called - why not add some logging to see what's happening?
