Creating data dictionary type using custom java class

[Former Member]

Hi Experts,

I have a situation involving the TableSorter mechanism as described here:

In order to do my sorting correctly, I've created my own Java class implementing the Comparable interface. Based on this class, I need to define my own data dictionary type to be used in a context/table.

However, I cannot se how this could be achieved as standard Data Dictionary elements can only be based on simple built-in types. Any ideas?

Kind regards,

Hi,

In short, do you want to create an attribute of your type?

Hi Appapparaj,

Yes, this is exactly what I want - to create a new attribute defined of a new DD type based on my own Java class.

Hi,

have you tried to use the following steps while creating your attribute

1) Right click on the context

2) New->Attribute

3) Manually-> Provide a name for the attribute

4) Browse->Select java native type and select your class

Yes, off course!

Thank you, I've been too focused on creating my own type instead of just creating the attribute.

Thank you very much.

Kind regards,

Too fast too furious...

This actually works, however, the mechanism does not support binding the context element to a view - it seems that only built-in types are allowed here.

Any suggestions?

Hi,

Yes, an object type cannot be bound to most of the UI elements, they expects a specific data type. If you could tell the scenario where you need to bound this to a UI.

I need to create a specific data type for table sorting. It is imperative that I control how this specific column is sorted, hency creating my own class was my best idea...

Hi,

have you tried the table sorter class available to do this?

Their you can have your own comparator for columns. Hope this will help to make your own sorting logic to be implemented

Hi,

Is that u want to use dictionary types to create your context ?

if it is so u can create a structure type in the dictionary and there u can have

a simple type for each attribute .

and while creating the node u can check tyhe check box crete with structure binding .

Hi Satya,

No, this is not what I want - see reply to Ayyapparaj.
