Exception saving templates

[pjsmith]

Hello,

I made a couple small changes to an indicator of mine yesterday, namely add Brush colour and Font to the configuration parameters. This all works fine, but I noticed today on startup the indicator had dissapeared from my workspace (again). I restored from the template, but my colour changes where not there (I'd not saved it again last time), so I tried to re-save the template with my new indicator colour settings. It fails with an XML error. I tried to also set the new colours as the default parameters for the indicator. Again, the xml parsing fails and NT throws an exception.

From the indicator/code point of view, all works fine, so I'm not sure I've done anything wrong (code is per examples in the official code base)

I simply added this to my settings. As I say, it works fine apart from this error in nt

Here's the exception detail from the trace log. It's seems it cannot handle the brush?

this is with 8.2 version

Hello pjsmith,

Thank you for your post.

Are you ensuring you are serializing the brush colors? I recommend using the example at the following link as a guide: http://ninjatrader.com/support/forum...43&postcount=2

[pjsmith]

Thank you. I was not.

There is no such requirement for fonts (SimpleFont) ?

[NinjaTrader_PatrickH]

pjsmith,

This would not be needed for SimpleFont.
