Hi,
Using the FilterBuilder, is there a way to search for Master Fields by specifying specific detail fields?
I.e. given the following DSs
and
and Code
is it possible to formulate a query like Detail field contains detail1 and detail2 and not detail3 to return corresponding Master fields?
Using the standard filter Editor (above the grid), it is possible to formulate or queries like Detail field contains detail1 or detail2 or detail3 which work without problems. Since I need more complex queries, I tried the FilterBuilder but it did not generate proper Critieria even when simulating the filter Editor.
I.e. When selecting some values in its SelectItem, the filter Editor generates
whereas the FilterBuilder (using is one of) generates criterias like
In addition, I cannot properly set the detail fields in the FilterBuilder (i.e. values are forgotten and in the field it just shows detail7, detail7 when in fact detail6, detail5 was selected; see screeshot). This all looks like a bug to me. An Eclipse project showing the issue is here (https://dl.dropboxusercontent.com/u/18305668/MasterDetailFilter.zip) for reference (LGPL libs need to be put in libs and the project needs to be compiled).
Thanks & cheers,
