This is the same post to  this post . It achieve the same result of PPR. This is used when somehow PPR in the table isn't working properly. For instance, you have a transaction process on the selected row in a table. You select the row in the table, and click the button which will perform the transaction process, but somehow the table isn't refreshed to the updated state of the row (even though you setup the PPR declaratively). But you alway could solve this programmatically. Here I posted the snapshot of the coding snippet. You can call setSelectedRow(getSelectedRowStr()) inside the actionListener of the button which will perform the custom transaction. Another scenario: if you have a called task flow to process some transaction on the table and upon return to the calling task flow, the user wants to see the transaction changes which were performed during the called task flow. The solution is you can add a method action in the calling task flow...

I am correcting myself. I think I could not find a way to reference the value in a ADF table column using EL outside the table component. As we all know, the value in the column of ADF table is referenced by using EL " #{row. AttributeName } ", while "row" is defined in the ADF table component attribute - "Var" by default. If there is a scenario that you have to reference the value outside of the table: for example, you have a button outside of the table and will be dynamically disabled if a value in the table is null and enabled if a value is not null. The question is, how you gonna reference the column value out of the table. Using the IteratorBinding EL is not accessible, I was trying to use #{Bindings.IteratorName.AttributeName.inputValue} to reference the value but it failed, since it is not the way it should be referenced. It is a attribute of the active Iterator binds to the table so simply it should be using the attribute binding. When drag and...

It's very common that the requirement asks to handle data manipulation for a ADF table. The data manipulation could be update, create or delete the table row and change some of the attributes in a table row. User interface experience should be achieve as that once the action button/link for the data manipulation has been pressed, the changed data should be reflected right away. It's not acceptable that the user has to refresh the page or search table to render the updated data. Solution to this concern is easier to be fulfilled via declarative handling in Jdeveloper 11g. Setup the "refresh", "refresh condition" of the iterator that the table binds should be considered first to utilize the "PPR" feature of the ADF. But sometimes the declarative handling does not behave as expected, and you need to achieve this manually as a workaround. Here is how I achieve this. Assume we have a manged bean to handle the data manipulation codes. After we select...
