I have a strange problem with a variable that looses text.
I made a button to load a file, and the name of the loaded file will be displayed in a variable. So far no problem, but when i press the load button, the open dialog pops up and when i choose cancel instead of a file the variable is empty. Nothing strange because i didn't pick a file. But when i try to load an other file then the loading goes good, but the text var stays blank.
I also tried to reset the variable etc. The only thing that helps is to start the application again.

What can be the problem?

displayed in a variable.

How?

More details if using TextInput object. e.g., what properties and settings?

You also do not say if using Page var... persistent/non-persistent. Etc, etc. those things matter.

This is because Opus returns a null / blank to your variable. It can be as useful as it is a pain.

The solution is to read the contents in to a tmp variable first and write it back if null / blank after the file browse action.

I thought i solved the problem but i still have the same problem when i break up an "open file" action.
What id did is:
Open file and store result in var LOAD1 (use it as a temp var) If LOAD1 is empty do nothing,
if LOAD1 contains data then set a delay of 0.3 sec. then set var LOAD1 to READ1 (the target var) but the problem stays.
How do i have to make a temp var in this case?

Post your code. Eliminate guesswork.
