Add and delete records (Parent/Child) in POJO Based ADF TreeTable


Hello All

Previously I have posted about creating POJO based ADF TreeTable , Get Selected Record from POJO based TreeTable and Traverse POJO based TreeTable

Recently a developer asked me about adding and deleting records in POJO based TreeTable so here goes a new blog post

To add records in af:treeTable first we have to check that if user has selected any parent node then new record will be added under it and if there is no selection then new record will be added as parent node, This is the core concept of this post and all these posts uses same sample application and same 2-Level Tree

Change in Comment Section- Google+ comments removed


Hello All

I have changed comment section of this blog to old blogger comments from Google+ comments.
There are lots of problem in Google+ comments as there is nothing like comment moderation, I don't get notification about new comments, even I am not able to view all comments etc

So I decided to move to default blogger comments but in doing so I lost all valuable Google+ comments :(
It means there are no comments on posts that were made using Google+, I know it's a great loss but you know A little effort now is better than any effort later

Looking forward to your comments :)

ADF Basics: Use transient attribute to show description of selected value in case of input and combo Lov


In ADF often We apply LOV on a ID attribute to show it's Description to user, This works good in case of choice list (selectOneChoice) but if we use Input Text with List of Values (<af:inputListOfValues>) or Combo Box with List of Values (<af:inputComboboxListOfValues>) then after selection ID appears on page instead of  Description like this


So to avoid this we apply LOV on a transient attribute that shows Description and sets ID value DB attribute, See how to implement this

Open af:inputListOfValues popup by calling JavaScript programmatically


af:inputListOfValues provides option to open Lov values in a popup and allow user to search, We can open this popup by clicking on magnifying glass icon


Recently I have seen a thread on OTN forum where user wants to open lov popup on a button click after checking some conditions and also found a post by Frank Nimphius Where he used javascript to open Lov popup on double click of mouse.
So guess what I have done ? ;)
Just called that javascript fucntion programmatically on button click
