Parameterized magritte components again

I brought up the topic twice already. There is always a few months in between. The topic back then was the parameterization of component links when embedding them into a pier page. The first problem did Lukas already solve. If I provide a description with parameterName in my component I can get the parameterValue in my component. A MyMaComponent class>>descriptionChild ^ MAStringDescription new parameterName: 'child'; accessor: #child; label: 'Child component'; priority: 100; yourself enables me to specify +mycomponent|child=title+ on a page and the component will get the "title" value through the child: setter. That is really nice. But the origin of my problem is a step further. In my last project I had big trouble accomplishing the wanted design by using renderers and componentClasses. I wanted to have a more freely doable design. So the idea was to have a wrapper component around a MAContainerComponent that has the child description. With the child parameter I could select the child of the internal MAContainerComponent to display. Unfortunately the component mycomponent I get by doing +mycomponent|child=title+ +mycomponent|child=abstract+ are not the same on one page. Is there a way to specify that I want to use the identical component if the embedded label (mycomponent) is the same? May I did something wrong but I always get different objects and it does make sense to me . Would be nice if this would bedoable. Otherwise I guess I need to do my own component-per-page-cache. Any hints appreciated as always. Norbert
