Hello all,

I'd like to report a series of errors where I am unable to save, export, build, send to contest or do a historical test with any programs I make. Unfortunately I cannot upload an example of the system since it seems to be more related to the interface of visual jforex itself. For more details, these are the specific errors:

Save: Unresponsive
Open: Server Error
Export: Unresponsive
Historical Test: Can choose initial options but on the second box the "Run" box is unresponsive
Build: Opens "Save" box, but save button is unresponsive
Send to Contest: Opens "Save" box, but save button is unresponsive.

I've already tried updating flash, java and firefox and everything is up to date, and I have restarted my computer numerous times/relogged in multiple times. I'm not sure what else to attempt. Thank you for reading.

Greetings and thank you for the report!

In order to reproduce that we need couple of more information like environments info, which browser, version, os version + flash player version

As much details as possible would help us to identify the problem, any error message would be helpful, too.

Thank you!

Operating System: Windows 7 Premium
Internet Browser: Firefox version 27.0
Java: Version 7 Update 45 (1.7.0_51-b13)
Flash: Version 12,0,0,44

There are no error messages that have come up, just unresponsive buttons.

Edit: The same errors happen in Internet Explorer (Version 11) as well.

I have discovered the source of the problem!

In earlier drafts I was able to use the Calculation Expression Block to find the highest or lowest point of the previous candle using the historical block. I used "min(A1,A3)" with A1=LastCandleOpen, A2=LastCandleClose and A3=LastCandleLow. Now it no longer allows me to save, test, or export the program if I use this command. I also cannot delete any Calculation Expression Block which includes it.

Is my formula wrong or is there a bug that does not allow Visual JForex to use the formula?

Hi, homework527.
I found a escape way for that bugs.
Please try it.

e.g.

This Strategy(SampleA) could export file.
Image
[max(Number, Number) is OK]

But This Strategy(SampleB) could not export file.
Image
[max(Cell, Cell) is not OK]

And, I don't know why, This Strategy(SampleC) could export.
Image
[max((Cell), (Cell)) is OK]

Thanks,
