multi timeframe indicator chart crash

[saltminer]

Hi guys,
I've got an indicator which can load up to 4 additional timeframes, of the same PeriodType as the chart.
The indicator works fine, but after a few times of opening the dialogue window and changing the user inputs for the periods of the additional timeframes or the number of additional timeframes, the chart seems to crash. After hitting OK that last time, the chart is blank and the menu icons are greyed-out.

Ninja is still responsive.
There is no entry in the Log tab about any error or exception.
There is no text bottom right of Control Centre about loading data.

There are no while() loops in the code to cause an infinite loop.

I've dug this out of the trace file. Can you shed any light on the situation for me?

saltminer, would it be possible to test for us with a simplied script using the same MTF structure to reproduce here? Are you seeing this on our latest version NT7 R8?

I am having the same problem. Has any cause been identified since this post was made?

There is a try catch block bracketing my Add method and it is not trapping any errors when the offending object is being ADDed.
