Hi, Today when i tried to launch the Ignition from the Network i assigned my system ip as 192.168.0.250 and the other system ip as 192.168.0.251 and I can open the Gateway status page and Launch the Project but when i Launch the Project, after the logon page, I receive the following error, when i launch the project [color=#0080FF]

We have been unable to reproduce this issue. The underlying cause: ```auto Error trying to coerce '-1' to a class java.lang.Integer ``` … makes me wonder if there aren’t some regional settings coming into play. What operating system are the two computers using, and what regional and language settings are they set to? ---

yes they are just english and arabic settings are not enabled on them so, the problem must have been arriving from the Arabic Enabled laptops / systems um… ---

Ok, that should help us narrow it down. Never would have guessed that -1 wouldn’t be considered a number. We’ll have to use a non-regional-aware number system for the system in question. ---

Sure, that makes sense. Never would have guessed that it would mess up number parsing. ---

Trying to replicate this in-house so we can test it. I don’t even have an arabic option in my “Regional and Language Options” box - is it a windows add-on? ---

you can navigate to regional and language settings and add language / check extend support to right to left languages and under keyboard / languages select Arabic … you may have to put windows installation cd when the system prompts, for more information google it or [support.microsoft.com/kb/821080](http://support.microsoft.com/kb/821080)
