Dear All,
I have one customized content fragment model called smartwidget as shown below.

************************************** END *******************************************
And I have created 2 CF by using above Model and below is the JSON
********************* First TESTING1 JSON *********************************************
{
"widgetSectionLabel": "testing1",
"actionWidget": [
{
"widgetName": "displayConditions1",
"widgetId": "display_Conditions1",
"title": "Testing1"
}
]
}
*********************** Second testwidget JSON *****************************************
{
"widgetSectionLabel": "testing1",
"actionWidget": [
{
"widgetName": "displayConditions1",
"widgetId": "display_Conditions1",
"title": "Testing1"
}
]
}
Now my requirement is that I want to merge the above 2 JSONS (means 2 content fragments) and want to make one JSON but when I am doing so I am not getting any JSON response as below

Hi @subnaik
Have you written custom servlet to get the JSON response for content fragment data ?
If yes, please check if there is any errors in logs while iterating through content fragment data
Thanks

Yes we have written custom servlet for the JSON.

Hi,
Get the jsonObject for the content fragments, and merge them like below in your custom servlet -
JSONObject Obj1 = (JSONObject) json1.get("cf1"); //jsonObject for 1st content fragment JSONObject Obj2 = (JSONObject) json2.get("cf2"); //jsonObject for 2nd content fragment JSONObject merge = new JSONObject(); merge.put("Object1", Obj1); merge.put("Object2", Obj2);
If you facing issues, please post log details if any
Thanks

Hi @subnaik
First I would say that proper wording is not that you wantvyo merge two content fragments (that is not possible) but rather you want to aggregate the JSON representation of each into a single JSOn and return that.
I have a confusion about the relationship between what I see in first picture and what Insee in second picture.
In the second picture I see you have a servlet. I assume here you have implemented a logic that looks up for the two content fragments based on the selectors you passes down to the servlet. You need to do a debug (in parallel with checking the logs) and see where it crashes. The execution chain is large so in any point you could have ommited something. Maybe you did not return properly the servlet response. Maybe you have a hidden NPE. Mayne your CFs could not be found by the code and so on.
Now about the first picture ? Do you use that to combine your CFs data? What is that? Is it a simple AEM component or another type of content fragment like an aggregetor of the first type ? Do you have a Sling model mapping on them or how do you use it to return aggregated JSON ?

Hi Please see my response in below.

@subnaik - Yes I want to merge also 2 content fragments in one content fragment by using fragment reference in the model, as shown below.
We have already written custom servlet which is coming fine without using the fragment reference in the content fragment model, as shown below.
But when I put the fragment reference in the model and trying to hit the same servlet then it is not coming fine and coming below error.

Hi @subnaik
Allow me to consider that referencing two CF in parent CF is still not the same as merging two CF. Unless you take the two JCR nodes and make one out of them, it is not called merging, but rather data aggregation. But again, this is only my view, aside from the actual issue you are raising.
As for the issue itself, now the first picture you shared makes sens. Can you share some code snippet to show how exactly are you reading the parent CF in your servlet ? Also if you have logs entries would be helpful ? The more info you provide the better help you can get. It definitely looks like a code issue as long as without references it is working, and with referencing is not.
