T5, newbie: Grid use w dynamic columns
Trying the hard parts first, I'm trying to create a table where the columns are not known until runtime. The application is basically a viewer, and the underlying database schema varies from time to time. My question: is it somehow possible to define what columns to use in the Grid component in runtime? The T4 variant accepts a list, so it's no problem. The T5 variant uses a bean to define the columns, and this is trickier. I've tried to use javassist to modify a a bean dynamically, but the Grid complains that it cannot find the source for the getter method I added to the bean. This might just be the wrong way to do it, something wrong with my first attemps to use javassist, or some problem with the idea to use these kind of modified beans as source for the Grid.
