startLocation for Category picker

[bimsimala]

Hi,
in share i have a data list of a custom content type. The type has property (defined through an aspect) of type d:category.

In alf Explorer->Category management i defined some categories, i.e.:

Cat A
   Cat A.B
      Cat A.B.1
      Cat A.B.2
‍‍‍‍‍‍

I want the user to be able choose from children of Cat A.B

The form options for this field are defined like this:

<field id="pi:itservicecategories" label-id="label.pi_thecategories" description="the category" set="info">
   <control template="/path/to/category.ftl">
      <control-param name="multipleSelectMode">false</control-param>
      <control-param name="startLocation">alfresco://category/root/Cat A/Cat A.B</control-param> 
      <control-param name="parentNodeRef">/Cat A/Cat A.B</control-param>
   </control>
</field>‍‍‍‍‍‍‍

How to define the startLocation and parentNodeRef correctly. I', always getting errors cannot read children of null.

I implemented this successfully. Here is the code:

<field id="CoP:topicValues" label="Product Services" set="classify" >
    <control>
        <control-param name="startLocation">/cm:categoryRoot/cm:generalclassifiable/cm:Cat_x0020_A/cm:Cat_x0020_A.B</control-param>
     </control>
</field>
‍‍‍‍‍‍‍

Note that spaces are replaced with x0020 which corresponds to ISO9075 requirement.
I did not use the parameter multipleselectnode false since I want to allow multiple options.
