Working with a Simple Matrix

The Simple Matrix requires that you have an Association Type defined between the two Object Types you want to show.

Simple Matrix can only be used on an Object Page, where one object is therefore the focus.

It creates a table which shows Associated Objects for the object in question as column headings, and then within the cells shows other objects that are also associated to those Associated Objects.

For example, if your Object Page was focused on a Process, you could use the Simple Matrix to show which Risk objects your Process is associated to, and then beneath each Risk also show which other Processes are also associated to those Risks.

When you use a Simple Matrix, the first level of Associated Objects are listed as columns in the table - consequently the more you show, the wider the table will be.

We therefore recommend that you restrict the number of Associated Objects displayed in the Matrix or it may become unusable.

To display a Simple Matrix in your Object Page:

These instructions assume that you are adding your Simple Matrix to a Tab on an existing Object Page, and that the new Tab node already exists.

  1. Right-click the Tab you want to add the Simple Matrix to, and choose New Association > [object-type] > [association-type]

This is to choose the Association Type you want to use to populate the column headings

An Association Type node is added.

  1. Expand the Association Type node and switch the Layout to Empty.

To do this: Right-click the Layout and choose Switch Layout > CW > Empty

  1. Right-click the Layout Empty node and choose Add Behaviors > Matrix > Matrix (Simple)

  2. Right-click the Association Type node created at step 1 and choose New Association > [object-type] > [association-type]

This is to choose the Association Type you want to use to find out which other objects are associated to each Associated Object returned by the parent node.

An Association Type node is added.

  1. Save your Site.

Please ensure you use unique Object Group IDs for the Association Type nodes.

If you have IDs which are the same as ones you have used elsewhere, you will see an error reported when attempting to Deploy the Site.
