TreeDataGrid grouped by enum

Support
#1

Hi, I have been trying to group information from a treeDataGrid by an enum, but it does not recognize it. Is it a feature issue, i.e. it is not possible to do it at the moment, or is it a bug?

Every time I try to activate it the information can’t be seen.

<treeDataGrid id="inventClassificationsDataGrid"
                  width="100%"
                  minHeight="20em"
                  dataContainer="inventClassificationsDc"
                      hierarchyProperty="classificationType"
                  columnReorderingAllowed="true" multiSort="true" multiSortOnShiftClickOnly="true"
                  multiSortPriority="APPEND">
            <actions>
                <action id="create" type="list_create">
                    <properties>
                        <property name="openMode" value="DIALOG"/>
                    </properties>
                </action>
                <action id="edit" type="list_edit">
                    <properties>
                        <property name="openMode" value="DIALOG"/>
                    </properties>
                </action>
                <action id="excelExport" type="grdexp_excelExport"/>
                <action id="remove" type="list_remove"/>
            </actions>
            <columns resizable="true">
                <column property="classificationType" filterable="true" frozen="true"/>
                <column property="identification" filterable="true" frozen="true"/>
                <column property="name" filterable="true" autoWidth="true"/>
                <column property="classification" filterable="true" autoWidth="true"/>
                <column property="hidden" textAlign="CENTER"/>
                <column property="tenantId" filterable="true"/>
            </columns>
        </treeDataGrid>

Best regards,

Hi!

I was able to display the enum column as a hierarchical column:

There are no software restrictions on using enumerations as a hierarchical column.
Most likely, the display breaks due to the fact that some kind of hierarchy in the entities is broken. For example, an entity doesn’t have a reference to itself or something else.
