Proposed improvement to x:dataTable

[Herbrand Hofker]

Hello guys,

 

You are working on this <x:columns> extension:

 

I have such a solution working in sun's JSF.

 

I could not get the  "c" core taglibrary working with myfaces and Tomcat (why?)  so still working on getting all running with MyFaces.

 

It is part of a much bigger approach so sending more, needs much more explanation.

I put a lot in the colum and in a domain object:

 

Here is a snapshot of classes that I use:

 

public class Column extends SuperColumn {
    final Domain domain;
    final String defValue;
    final String checkStmnt;

    final Integer indexno; //here if this a primary /secondary key

   (can be used for further user interface refinement)
....

}

 

and

 

public class Domain {
    final Integer id;
    final String name;
    final Datatype datatype;
    final String inputType;   //here it can be selectBoolean etc.
    final Integer size;
    final Integer maxLength;
    final String defValue;
    final Boolean mandatory;
    final String checkStmnt;
    final String domainValidatorId;
    final String inputValues;
...

}

 

I hope to have time this weekend to join your efforts.

Neal,

Please report back here about what you learn and how you make out. We
are in the process of investigating this too.
