Developer Resource - Filter Overrides
Customizing a filter specification doesn't mean you have to write rewrite the existing ones when you take advantage of filter overrides. You can write a config file just describing the customizations you need for each filter specification. These XML config override files live in source\Web\Filters\custom\
.
An example overrides file is provided that demonstrates the capabilities of filter overrides.
It is located at source\Web\Filters\custom\cases.overrides.example.filter.config
<filter overrides="">>
<removeFacet key="" />
<removeField key="" />
<removeCategory value="" />
<removeColumn key="" />
<!-- all inherited attributes are available, here are the additions -->
<query>
<addFacet label="" />
<addField label="" />
</query>
<columns>
<addColumn index="" />
</columns>
</filter>
Example Filter Config File
<filter overrides="Cases">
<removeFacet key="priority" />
<removeColumn key="priority" />
<removeColumn key="contact" />
<query>
<addJoin relationship="case_reporter2contact">
<addField key="case_reporter2contact" field="objid" dataType="int"/>
</addJoin>
</query>
<columns>
<addColumn key="contact" template="entityLink" entity="Contact" idField="case_reporter2contact" index="-3" width="200">
<sorts>
<addSort key="contactLastName" />
<addSort key="contactFirstName" />
</sorts>
</addColumn>
</columns>
</filter>
One important thing to note is that when re-adding in columns, facets or fields you must pay attention to whether or not you want to re-implement the child elements of what you've removed. In this example we removed the column key contact
and had to re-add the sorts children to maintain our desired functionality.

This attribute is used to change or add a label to your new facet or field. For example the facet label appears in the dropdown listing of available facets. |
<addColumn>
Attribute Name |
Description |
index |
Instead of duplicating the existing column elements you can specify the position of your added column. The columns are 0 indexed. A setting of 7 would place this element in the 9th visible column since it comes after the inherited column's index. You can also use negative numbers here to force a column towards the left most position. |
