Hi

Is it possible to set a cross-table cells and plain table cells programmatically? Is there any API?

Hi,

I'm not sure I understand your question.
The values displayed in cells are computed from your EMF semantic model using the rules in your odesign file using the "label expression".
Unless I misunderstand your question, the normal way to change the content of a cell is to modify the underlying semantic EMF model and let Sirius refresh the table's cells accordingly.

If you try to change the text of a cell by modifying Sirius's own data model (i.e. the DCell objects), your modifications will be lost on the next refresh as Sirius will overwrite your change with the result of the label expression.

Hi

Thanks for answer! We can't change a semantic model directly, because we need to implement a generic "CSV to Sirius Table" importer. And the importer doesn't "know" the metamodel.

I'm not sure that it's a right solution. At now we use the following approach:
1) Get a feature for a cell using TableHelper.getEStructuralFeature()
2) Set the cell value using TableCommandFactory.buildSetValue()

It seems to work.
