I have dynamic view panel and I am using a customizer bean to hide columns based on column names. However, I need to:
Why I need this: in my application I am dealing with document mappings. I want to create a column for mapped document details. as there can be different document types mapped, there can be multiple columns.
The work of seeing which view you're working with and generating the column defs (normally the same as the ones in the view, but you could add others) is done via the ViewFactory object that is returned by #getViewFactory in the customizer bean. You can see an example of overriding the method and returning a customized factory here. You can also find the source of the default one in the ExtLib here for another example. The job of the ViewFactory is to emit a ViewDef containing a series of ColumnDefs - basically, an abstract representation of the view design. That will cover 1 and 3.
Getting a handle on the document in question for number 2 is a bit more indirect. Since the customizer bean executes only during the initialization of the view, it has no direct hook to the process of rendering each row (which is where you can get the document). You can, however, set properties or content to method/value bindings that, themselves, access the document, so that they're executed per row. I do this in order to get color columns working: I create an SSJS binding for the style property that can then see the viewEntry object. If you modify that code, you could write some SSJS like #{javascript:var doc = viewEntry.getDocument(); ...other stuff here...}. If you do that, you should make sure to either always use "viewEntry" as the var name in the view or use panel.getVar() to find the variable name dynamically.
