hi,
start a new b4j project, add a TableView (designer), change the 'Sub Button1_Click' code :
run the program, click the button, watch the LOG.
the 1-105 loop is just to replace 105 button manuel clicks, each updating the table.
in my machine, after i=100, there's an error in the log. the Table Crashes (stops updating), until the end of the loop.
for the question what do i need such a code for : i don't. i have same error/case in a huge project i'm on, and this is just a code where i can make this error happens.
What's behind it ?
Thank you
