Developing a Bulk Editor based Component: the Product List Component
This section provides an overview of how to use the Bulk Editor and gives a description of the existing Geometrixx component based on the Bulk Editor: the Product List component.
The Product List component lets users display and edit a table of data. For example, you can use the Product List component to represent products in a catalog. The information is presented in a standard HTML table and any editing is performed in the Edit dialog box, which contains a BulkEditor widget. (This Bulk Editor is the same as the one accessible at /etc/importers/bulkeditor.html or through the Tools menu). The Product List component has been configured for specific, limited Bulk Editor functionality. Every part of the Bulk Editor (or components derived from the Bulk Editor) can be configured.
With the Bulk Editor, you can add, modify, delete, filter, and export the rows, save modifications, and import a set of rows. Every row is stored as a node under the Product List component instance itself. Every cell is a property of each node. This is a design choice and it can easily be changed, for example, you could store nodes somewhere else in the repository. The query servlet’s role is to return the list of the nodes to display; the search path is defined as a Product List instance.
The source code of the Product List component is available in the repository at /apps/geometrixx/components/productlist and is composed of several parts like all Adobe Experience Manager (AEM) components:
- HTML rendering: the rendering is done in a JSP file (https://experienceleague.adobe.com/apps/geometrixx/components/productlist/productlist.jsp?lang=en). The JSP reads the subnodes of the current Product List component and displays each of them as a row of an HTML table.
- Edit dialog, which is where you define the Bulk Editor configuration. Configure the dialog to match the needs of the component: columns available and possible actions performed on the grid or on the search. See Bulk Editor configuration properties for information on all the configuration properties.
Here is an XML representation of the dialog sub nodes:

Bulk Editor Configuration Properties
Every part of the Bulk Editor can be configured. The following table lists all the configuration properties for the Bulk Editor.
Columns Metadata Configuration
You can configure for each column:
-
display properties: html style, CSS class and read-only
-
a checkbox
-
a forced position
CSS and read-only columns
The Bulk Editor has three column configurations:
- Cell CSS class name (cellCls): a CSS class name that is added to each cell of the configured column.
- Cell style (cellStyle): an HTML style that is added to each cell of the configured column.
- Read only (readOnly): read only is set for each cell of the configured column.
The configuration must be defined as the following one:
"colsMetadata": {
"Column name": {
"cellStyle": "html style",
"cellCls": "CSS class",
"readOnly": true/false
}
}
The following example can be found in the productlist component (https://experienceleague.adobe.com/apps/geometrixx/components/productlist/dialog/items/editor/colsMetadata?lang=en):
<colsMetadata jcr:primaryType="nt:unstructured">
<Selection
jcr:primaryType="nt:unstructured"
checkbox="true"
forcedPosition="0"
headerText=""/>
<ProductId
jcr:primaryType="nt:unstructured"
cellCls="productlist-cell-productid"
headerText="Product Id"/>
<ProductName
jcr:primaryType="nt:unstructured"
cellStyle="background-color: #FFCC99;"
headerText="Product Name"/>
<CatalogCode
jcr:primaryType="nt:unstructured"
cellStyle="background-color: #EDEDED;"
headerText="Catalog Code"/>
<Color jcr:primaryType="nt:unstructured">
<editor
jcr:primaryType="nt:unstructured"
store="[Blue,Red,Yellow]"
triggerAction="all"
typeAhead="true"
xtype="combo"/>
</Color>
<SellingSku
jcr:primaryType="nt:unstructured"
headerText="Sku Id"/>
</colsMetadata>
Checkbox
If the checkbox configuration property is set to true, all the cells of the column are rendered as checkboxes. A checked box sends true to the server Save servlet, false otherwise. In the header menu, you can also select all or select none. These options are enabled if the selected header is the header of a checkbox column.
In the former example, the selection column contains only checkboxes as checkbox=“true”.
Forced position
The forced position metadata forcedPosition lets you specify where the column is placed within the grid: 0 is the first place and <number of columns>-1 is the last position. Any other value is ignored.
In the former example, the selection column is the first column as forcedPosition=“0”.
Query Servlet
By default, the Query servlet can be found at /libs/wcm/core/components/bulkeditor/json.java
. You can configure another path to retrieve the data.
The Query servlet works as follows: it receives a GQL query and the columns to return, computes the results, and sends the results back to the Bulk Editor as a JSON stream.
In the Product List component case, the two parameters sent to the Query servlet are as follows:
- query: “path:/content/geometrixx/en/customers/jcr:content/par/productlist Cube”
- cols: “Selection,ProductId,ProductName,Color,CatalogCode,SellingSku”
And the JSON stream is returned as follows:
{
"hits": [{
"jcr:path": "/content/geometrixx/en/products/jcr:content/par/productlist/1258674828905",
"ProductId": "21",
"ProductName": "Cube",
"Color": "Blue",
"CatalogCode": "43244",
"SellingSku": "32131"
}
],
"results": 1
}
Each hit corresponds to one node and its properties, and is displayed as a row in the grid.
You can extend the Query servlet to return a complex inheritance model or return nodes stored at a specific logic place. The Query servlet can be used to do any kind of complex computation. The grid can then display rows that are an aggregate of several nodes in the repository. The modification and the saving of these rows must in that case be managed by the Save Servlet.
