MobileTableCellData Limitation?

Is there a limitation of rows with customCell ?
for me it work with 25 rows, but with more some stay blank.

I’ve filed a feedback case for this a while back. It’s a private case so I cannot link it here. Just out of curiosity: do you try loading data from a SQLiteDatabase?

I changed all those tables to be populated from a DataSource so I don’t have to use AddRow any longer. There is no issue with DataSource.

I populate from a external Rest Server

Use a data source on your table and there is no limit. Without a data source there may be limits since iOS tries hard to load tables dynamically.
