Changing DataSourceField title on the fly

[williamy]

Hi! I'm reading my datasource using DataSource.getDataSource. The xxx.ds.xml file has all the fields setup properly (with titles assigned).

However, I need to replace one of the titles of the DataSourceFields in the datasource after a transaction.

I tried doing this by calling datasource.setFields again (with the title change on the appropriate DataSourceField) but it complained that I couldn't do it.

How can I do this change with my setup?

Hi williamy,

if I understood correctly it's easy:
title=""-tag in ds.xml files is for display purposes only. You could just use setTitle(String title) for your ListGridFields (in a ListGrid) or FormItems (in a DynamicForm) after your transaction finishes.

I'm able to populate the datasource using setTestData, then passing the datasource into a listgrid with setDataSource. By calling fetchData on the listgrid, I'm able to see my data. I'm not populating the setFields on the listgrid at all. But you're saying that I have to use setFields to override the title?

Perhaps the following works on a loaded ListGrid:
public ListGridField ListGrid.getField(java.lang.String fieldName), eg. lg.getField("yourField").setTitle("newTitle");.

Best regards,

Unfortunately, what you suggested did not work. I suspect because there are no fields set with the grid (the fields are set in the datasource).
