ADF LOV Auto Suggest Functionality

ADF Faces LOV component can be easily enabled with auto suggest functionality. This is really powerful feature and should save time for user to search for required list values.

Auto suggest can be configured to be invoked only when certain number of characters is entered. I have configured Job ID list to trigger auto suggest, when two or more characters are entered. No auto suggest with single character:

Two or more characters entered - auto suggest displays filtered LOV values. What is nice about it - it automatically shows all these attributes included into LOV list:

In the background ADF BC executes SQL with bind variable from auto suggest:

LOV is defined on attribute in standard way, nothing special here:

To enable auto suggest behaviour, enough to drag and drop ADF af:autoSuggestBehavior tag into ADF Faces LOV component. Point suggestItems property to LOV binding suggestItems expression. Number of characters when to start auto suggest search is configure through minChars property:

Hi Andrejus,

If input LOV is a column in table, then I am not getting suggestItems from bindings corresponds to particular row.
Th code will be like this for inputLOV inside table:

Could you please help, how to get the suggested list of items inside table.?

Thanks in advance,

Hello Andrejus,
Do you know if, in 12c, something additional is required? Because following these steps does not work. And to see the binding, I see that method is empty and it does nothing.
Thanks for your answer.
Best regards

This sample is based on 12c.

Is there a way to restrict auto suggest trigger based on number of char entered?
Like I want to trigger auto suggest only for 3 or more char entered.

Yes, I think there is out of the box property for this.
