While creating a Building Blocks strategy, when adding a condition "Indicator Compare to Value" when I start typing "ind...", I get this exception:

I was able to recreate the problem. Steps...

Drag 'Indicator Compare to Value' into a block.
Click the down-arrow on the Indicator field
Type Ind
Exception occurs

Please update the Norgate extension to Build 2 to fix this.

Thanks, Glitch. I don't know if this will help, but I've never installed Norgate.

Hi Paul, I can't duplicate your exception locally. This is Build 32?

I also wasn't able to reproduce neither in B32 which has Norgate's plugin nor in B33 which hasn't. Neither the AOOR nor the InvalidCast exceptions.

I had the Norgate installed and the upgrade to Build 2 seems to have solved it indeed.

Thank you once again!

WL 8 build is 32. It happened on my junky laptop. I had a hard time recreating it on my main machine (no Norgate there either), but finally figured out what causes it...

Create a new BB strategy with only Buy At Market and Sell At Market blocks.
Drag an 'Indicator Crosses Signal Line' into the Buy At Market block. Ok the defaults.
Drag an 'Indicator Crosses Value' into the Buy At Market block. Click on the Indicator field drop-down arrow.
Type Ind.
Exception occurs.

I was able to recreate this problem multiple times.

Hope that helps.

I can confirm what paul1986 reports. I followed his instructions and got the exception:
