AEM 6.4. Retrieve values from another dialog.

You can set all values a component needs within its own dialog and then use Sling Models and @Inject as discussed here -- Building Experience Manager Components using Granite/Coral Resource Types

Ok and what if i have 2 components and i need to render dialog A properties in component B?

It something dynamyc and i cant let author do that.

Like i have "some cards components" and i have another component that must fill itself with "these card names" when the author adds them.

From what I understand you basically want a dynamic dropdown.

Once dialog A is saved - it just becomes content so what you want in the B component is to dynamically populate your dropdown with values based on content. For that there are a lot of examples. It was just answered here: Select value in dropdown in touch ui dialog based on the value selected in editable template (You need to determine the values in Java by traversing your content and picking up those card names).

Yes - you can do that (reuse values from another dialog) or build  your component dialog that lets an author set all values required for for that component.

I personally prefer the 1-1 approach. While its true, you are setting more nodes in the JCR dialog branch, its cleaner! In the end, the component has all values as properties. Then all values can be injected into the model simply by using @Inject.

Not really. I need the component 2 renders directly the html the values from dialog 1

yes, you can reuse dialog or part of of one component into another if that is what you are looking for.

Touch UI - Reuse Dialog Field

You can achieve using parent/child concept or Comp A should know the path of Comp B either way its tightly coupled.

you need to do following steps to achieve,

1. Add dialog load listener to Comp A ( which fires when dialog loads and opens)

2. Have AJAX call to hit the sling servlet

3. Have business logic in sling servlet or service to find the parent or B component and return the value

4. Assign the value to the Comp A field.

Note : You may need to educate the author to configure in some manner and its just one of the way to retrieve the values from other component.

Thanks!

This is not what i need. Because i need the fields populated from the other one.

Hi,

Please check ​Touch UI Dialog - include part of another dialog ​

I already checked that. It works because it replicate the fields. But my need is to populate those fields dynamically from the other dialog.

I try to explain better.

I have page.

I drop my component lets say "Card". It has 5 fields in the dialog that the author can change.

Then i drop my componet called "List of cards". The author can set 1 property called "List of cards Title.

What i need to achieve now is that this "List of cards" will render atleast 1 but even more, titles of the "card components".

Structure of Card component (everything authorable)

          -Title

          -subtitle

Structure of List of cards.

/////////Title (authorable)//////

          -subtitle (dinamycally from the Card component)

So if i have 4 cards with 4 subtitles.

The list of cards component will get 4 subtitles rendered dinamycally.

I wish now is clear
