Are v9 pickers with 2 level association paths supported?

[John]

I’m trying to use a picker for mda:DocumentMgrItem on a form of class BatchActionCommandAttachment. The association between these two classes is values=”attachment act”. This two-level path passes validation but when saving, the server receives null for ‘attachment’.

Is there a trick to make this work?

Here’s the form

<Layout class="BatchActionCommandAttachment"> <UIActions/> <Composite name="composite"> <Table caption="idsf.ActTemplateDocumentList.DocumentManagerItems" deletePrompt=" " factory="BatchActionCommandAttachment create" mode="BatchActionCommandAttachment attachment act" name="tblDocumentManagerItems" ref="mda:DocumentMgrItem" rows="(@)" values="attachment act"> <Toolbar name="tableToolbar"> <Item action="true" caption="ids.add" event="sysPick" icon="plus_grey" name="pickDocument"/> </Toolbar> <Menu name="rowMenu"> <Item event="sysRemove" name="deleteItem"/> </Menu> <Column caption="ids.templateName" name="colType" sortable="false" values="attachment act title"/> <Column caption="ids.documentMgrItem" name="colTitle" sortable="false" values="attachment attachment fileName"/> </Table> </Composite> </Layout>

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

<Layout class="BatchActionCommandAttachment">    <UIActions/>    <Composite name="composite">       <Table caption="idsf.ActTemplateDocumentList.DocumentManagerItems" deletePrompt=" " factory="BatchActionCommandAttachment create" mode="BatchActionCommandAttachment attachment act" name="tblDocumentManagerItems" ref="mda:DocumentMgrItem" rows="(@)" values="attachment act">          <Toolbar name="tableToolbar">             <Item action="true" caption="ids.add" event="sysPick" icon="plus_grey" name="pickDocument"/>          </Toolbar>          <Menu name="rowMenu">             <Item event="sysRemove" name="deleteItem"/>          </Menu>          <Column caption="ids.templateName" name="colType" sortable="false" values="attachment act title"/>          <Column caption="ids.documentMgrItem" name="colTitle" sortable="false" values="attachment attachment fileName"/>       </Table>    </Composite> </Layout>

Hi John,

In the mean time we get someone to respond to the technical question.

Have you investigated how the Activity Plan – attachment picker is implemented? That control allows you to pick items from Document Manager. Is it similar implementation ?

Dhruv, as mentioned on slack too, the difference between that picker and this one is the 2-level path I think.  I’ve had some success using a custom non-persisted attribute and a custom create method on BatchActionCommandAttachment but run into another issue, so any details on whether this is the right path would be appreciated.

Creating a non-persisted attribute for the picker to store the value to worked. Then I customized the before create of BatchAttachmentCommandAttachment to retrieve the attachmentLink from the DocumentMgrItem
