Identifying the source of the request for an LOV

The LOV can be enabled for an attribute of a view object, and the same can be used inside a query panel or in a parameter form.
How do you identify where the LOV is displayed currently, from a View Object?

Well, you can use the following groovy expression 'adf.isCriteriaRow' to achieve the same, which may rerun true if the request is from a model driven af:query component. This is useful if you need to switch between LOV definitions based on where its displayed at run time (e.g: one LOV in search panel and a different one in parameter form for the same attribute).

Please see the following topic in Dev Guide to learn more - How to Specify Multiple LOVs for an LOV-Enabled View Object Attribute
