I fear the answer is no as it was in Vision (well, it was possible, but extremely flakey and dodgy to do), but can we create bindings via script in Perspective?
The alarm status table is causing us grief (slow performance for 25k alarms) and also isn’t customisable enough to display how I want our alarms to be displayed (would be nice if we could provide a View to use for each row), so instead, I’m creating my own viewer using a flex repeater. I want read all alarms within the path filter and then read the alarm IsActive properties and want to hide them in the flex repeater if off. However to do that I have to set the
instancePosition param values which are outside of the flex’s templates. I thought that I could instead use an output param in the template View to create this and then bind the keys based on the status of the alarm, however I can’t bind to an object’s children if it’s a param, even if if it’s an output…
Actually, I will try binding the
instancePosition to a
custom.instancePosition instead. This works crisis averted
