I believe that one image is more than 1000 words. That is why here goes my image:
On the left you have veeeeery simplified data structure i have now. More on the right is what i have right now (one component which is used on Page 1 used to define issues) I want this component to show categories assigned to issue. And have the button to category chooser (this is Page 2)
My main question would be - how to structure it? What should be the component parameter for example (for now it is issue)
I have no issue with displaying available categories on page2 (with backend query) The issue is, how then to navigate back from page2 to page1 with the categories selected. And how in component to show those selected categories (i have working solution with custom function JOIN and then if the parameter assigned to Text is List<string> i can use this join function to display correctly it in form: "Category1, Category2") But i suppose that this component should take issue as a parameter. And it should display Issue->IssueCategories (but how? I have issue with List of references only, not the documents itself?)
