Link sevhist object to method toolbar

Hello,
I've putted all my sevhist objects into a grouped hierachy to have the operator find them fast without going trough all the different objects. This gives my a problem having the sevhist objects correctly linked in the method toolbar.

Is there a way to link them so that the sevhist objects can be opened from the toolbar without having the sevhist objects directly as a sibling unther the logged value?

Hi jds,

The History method will look for an attribute with name 'DefHist' of type AttrRef that points to the SevHist. If this doesn't exist it will look for a child object of type SevHist or SevObject. DefHist doesn't exist in the Component object so normally is will not be found, but if you create such an attribute in you class you can point it to the SevHist object.

Claes,
it isn't fully clear to me what typeref I need to fill in, nor am I not very shure if I use the correct flags (in this case "class".
 

Hi jds,

The name should be DefHist, not DevHist.
TypeRef should be pwrs:Type-$AttrRef.
Flags should be 0.

Idd,
in the meantime I found out the switch between F and V and looked a bit further than my nose long (copy paste DefTrend).
The icon shows up, but the hist doesn't open.
For ex. I've made a sevhist object in the hierachy plant-hist-tstlog. The DefHist attribute is filled in with "plant-hist-tstlog"

There is a bug here. The filtering function that decides whether the icon should be visible or not looks for 'DefHist' while the opening function looks for 'DefHistory'. As a work around you could define both attributes in your class.
