[1.1.0] IDE: problems with scripts having an image file with size 0 byte (however this happened ;-)

[sgfit]

Sikuli 1.1.0, Windows 7 x64.

When attempting to save a .sikuli in the IDE, instead of saving, the contents of the .sikuli folder are deleted and the IDE returns the error message "[error] EditorPane: read returned null". The contents of the previous .sikuli script are still present in a tab labelled 'Untitled'.

When attempting to save the tab labelled untitled, the IDE returns this error message, and the .sikuli folder is not generated:
"[error] EditorPane: read returned null"

Restarting the IDE then returns:
"[error] EditorPane: read returned null"
"[error] IDE: restoreScriptFromSession: Can't load: C:\Users\username\Documents\Sikuli\project\win7.sikuli"

Permissions for the folders in question allow reading and writing, so doubt it is a file permissions issue.

Steps to reproduce:
1. Create a large script (>200 images, >1000 lines)
2. Attempt to save.

I think I found how to fix it in my case, but not the ultimate cause.

When I saved a new screenshot from sikuliide, the resulting file was saved as a 0-byte file. Attempting to save or open the .sikuli from then on caused the 'read returned null' error mentioned before.

I haven't tracked down why the screenshot was saved as a 0-byte file, but if this error comes up for anyone else, that's probably the cause.

thanks for tracking this down. Lets see what I can do.

I got the same bug : I can't open a sikuli folder. I was able to open it the past days but I am not able to do it now. "EditorPane: read returned null"

I reinstalled Java, nothing happened.

I have cleared the 0-byte screenshot and my problem is still there.

One thing that can be nice to know is that even if the sikuli folder is "rejected" by the IDE, I can't delete the *.py file of my project/sikuli folder. Maybe it can lead you somewhere.
