extending a form in Servoy 6

Classic Servoy
1

I am trying to create a form that extends a template form (done in the designer: name is contained in template_frm).
In the following snippet child_frm is a string, servername and tableName are strings and all are valid.

var child_frm = template_frm + '_sub';
var subForm = solutionModel.newForm(child_frm, serverName, tableName, null, false, 0, 0);//ignore width and height 
subForm.extendsForm = solutionModel.getForm(template_frm);//TODO this fails to extend the form - why?

After this code the subForm.extends remains null.
Under what circumstances will the “.extendsForm” fail silently?
Note neither form has been loaded nor shown prior to this code executing.
(Servoy 6.0.0)

Hi Thomas,

your method should work correctly.

Thinking of ways were you can’t extend templateform on the subform:
datasources should match or datasource of templateform should be ‘none’

Hope this helps
