Missing ribbon on subgrid in dialog

[OndrejJuda]

Hi,

ribbon on subgrid inside a custom dialog box stopped showing. Ribbon with buttons like 'create new record', 'activate', 'delete', etc.

As I opened dialog yesterday I was expecting something like this:

But I got this instead:

As you can see the ribbon is missing and even command debugger did not work for me because it appears in the ribbon which is not there.

Do you have any idea how this could be solved?

Some info about subgrid in dialog:

There is a slight difference between subgrid in dialog and classic subgrid with related records. Subgrid in dialog has to be unbound as other dialog components so we cannot use tag. Because of this, it can't show only related records as it is and it has to be filtered using TypeScript on load of subgrid.

Classic subgrid:

<cell locklevel="0" id="{4d1b4bb5-a772-4d9b-b63e-847fbfac39de}" rowspan="1" colspan="1" showlabel="false">
  <labels>
    <label description="QUOTES" languagecode="1033" />
    <label description="NABÍDKY" languagecode="1029" />
  </labels>
  <control id="quotessubgrid" classid="{E7A81278-8635-4D9E-8D4D-59480B391C5B}" indicationOfSubgrid="true">
    <parameters>
      <TargetEntityType>talxis_salesquoteheader</TargetEntityType>
      <ViewId>{112CF9BD-E6F4-4AD8-9C5D-10E9D328DC1D}</ViewId>
      <ViewIds>{1AE61DB4-322E-4A82-A872-F129DFAD46DE},{112CF9BD-E6F4-4AD8-9C5D-10E9D328DC1D}</ViewIds>
      <EnableViewPicker>false</EnableViewPicker>
      <RelationshipName>talxis_talxis_opportunityheader_talxis_salesquoteheader_originatingopportunityheaderid</RelationshipName>
      <RecordsPerPage>10</RecordsPerPage>
      <EnableJumpBar>false</EnableJumpBar>
    </parameters>
  </control>
</cell>

Subgrid in dialog:

<cell id="{d666654d-ef9f-4965-a54f-de723b4a57cd}" showlabel="false" >
  <labels>
    <label description="QUOTES" languagecode="1033" />
    <label description="NABÍDKY" languagecode="1029" />
  </labels>
  <control id="quotessubgrid" classid="{E7A81278-8635-4D9E-8D4D-59480B391C5B}" isunbound="true" >
    <parameters>
      <TargetEntityType>talxis_salesquoteheader</TargetEntityType>
      <ViewId>{9F6AF942-7DD7-47A4-AC16-BCE54FDB2E13}</ViewId>
      <EnableViewPicker>false</EnableViewPicker>
      <EnableJumpBar>false</EnableJumpBar>
    </parameters>
  </control>
</cell>
