Passing Sling Model property from parent to child parsys component

[Giuderos1]

Hi all,

as mentioned in the title is it possible to pass a sling model property to a child component dragged in a parsys?

I want to call an intensive method only once in the parent and then pass the result to all child components dragged in the page.

Do you mean this structure?

 component 1 (which contains this intensive computation)
  |-> parsys
    |-> sub component 2 (which

 In this case it is hardly possible, because the parsys does not do that (at least that I am aware of).

When I was required to do so always in the context of a request, I used the RequestParameters and stored the result of the computation (and made sure that if the expected key was not present the computation was done again and stored in there).

Exactly, the same structure.

Maybe I found a solution which consist in setting the result of the computation in an attribute of the SlingHttpServletRequest

request.setAttribute("result", ruleList);

Then getting the attribute in the Sling Model of the child component and assigning it to a variable

String ruleList = request.getAttribute("result");

Could be a possible solution?

I used this approach succesfully.
