Sorting field from subordinate context node

[Former Member]

Hi everybody,

I have a quite tricky problem:

I like to create a table view which displays attributes from BuilHeader and from BuilAddress.

I created therefore a context node BuildHeader in my view and BuilAddress as subordinate context node, linked together by BuilAddressRel in creation assistent von context node BuilAddress.

When I open the structures view of context nodes, then the parent- and child relationship of both context nodes is visible.

As it is not possible to insert attributes to a table view from no other context node than the directly assigned one (here BuilHeader), I created a new attribute for the address field, which I wanted do add to the table (the field "REGION"). I created the new field with assistant also and it seems to work.

Unfortunately the GET_* method of the new attribute was generated false so that I had to change the coding. I fetched the reason from the BuilAddress related entity and selected the region text for the region code. The region text has finally also been displayed but now I have the problem that I cannot sort this added atrribute column for REGION. All other columns can be sorted properly but only the one i need for sorting can't be 😞

Can anybody tell me if some kind of workarround exists to make this added column also sortable?

Thanks an best regards,

Markus

Hello Markus,

You might need to enhance the GET_P-method to make the field sortable end also eventually the EH_ONSORT-method as well.

I have created a thread about this in the past:

Hello Thomas,

I tried you recommended way but it did not work again. I deleted the attribute then and created it again as value attribute instead of a model attribute, filled the fields manually in DO_PREPARE_OUTPUT and now the sorting works without any manual adaptions of the code. So maybe it was a problem of model attribute.

Best regards,
