simple tips for AX coding which may work out

Sometimes, when developing, AX doesn’t work as expected, or behaves weird.
Here are some of the things you can try if you run out of ideas, roughly in the order I do:

Try again
You probably already did, but make sure you can reproduce the problem. If it only occurred once, it’s not a problem.

Check your code again
Check your code carefully for errors, and maybe ask a colleague’s opinion.

Compile
Your project might contain compile errors, so compile it to be sure.

Close the debugger
Sometimes, when the debugger is active, AX will keep executing ‘old’ code. Close the debugger to make sure the latest code is executing.

Compile forward
When you have modified a class that is inherited by other classes, you might want to compile forward this class.

Synchronize data dictionary
You may have made changes to application objects that haven’t been synchronized with the database. Open the AOT, right click on the Data Dictionary node and choose Synchronize.

Clear the usage data  and clear the cache for elements, form, other item from the

Tools>>option>>clear the usage data
Tools>>clear CACHE.

Restart AX client
Simple as that, close the AX client and start it again.
