Hi Myo,

Did you exported the strategy to your local computer ?
what is the name of the strategy file ?

Hello.

In attachment there are two files. One with Error #2030 when opening. Strategies are complex maybe, but only differences between files is couple of Calculation blocks, IFs and Assign block. Differences are grouped.

Regards

Greetings,

I managed to open and build both strategies as you can see attached.
I'm using VJF Mozilla browser and latest Java 7_65 version.
Is there any exception generated out of you console ?

Hi.
Got error with any browser (Firefox, Opera and IE), and I have latest java version (like yours).
This error happening only when try to open draft saved on server side. "Funny" thing is that same compiled file (Compiler --> Build) can normally be open!?
I think that's ok with finished strategy, but in development phase that could be annoying. But there is export option to local drive... :D

Understood now,

I managed to reproduce the bug and unfortunately this is not the first time that it happens.
We'll address it. Luckily we have the export function and I strongly recommend you to use it in a regular basis to avoid time wasting.

For such types of issues, the java console doesn't retrieve any message.
The Java console is described in here:

Thanks !

I'm glad that we understand each other.
Maybe I'm wrong but I think it is something with calculation blocks. Maybe VJF have some limitations numbers to use this kind of blocks...

Anyway, backup into HD is my 1st rule :mrgreen:
