Can you stop debugger hitting Debug::assert?

I have some code that I am trying to debug, but the debugger keeps stopping in Debug::Assert.

/// 
    /// Asserts the value of the passed in expression.
    /// 
    /// Expression to assert
    [Hookable(false)]
    public static void assert(boolean  _expression)
    {
        if (!_expression)
        {
            const int numberOfStackFramesToSkip = 2;
            var trace = new System.Diagnostics.StackTrace(numberOfStackFramesToSkip); // avoid the assert() method frame (and 'assert() one)
            XppRuntimeEventSource::EventWriteDebugAssert(trace.ToString());

            if (Debug::debuggerIsAttached())
            {
                System.Diagnostics.Debugger::Break();
            }
        }
    }

It seems its calling the Debug::Assert statement in some of the standard code in DimensionStorage that calls it, and I can't get passed it.
Every time I press Continue, it simply stops at it again.

Can I stop it from hitting it in some way?

Hi Rudi,

Which method are you debugging in DimensionStorage?

If the debugger is stopping at this statement, can you not set the parameter "_expression" to true in the watch window so that you can continue debugging?

I am not debugging DimensionStorage, I am debugging my own code.

If I change the _expression to true, it just continues and hits the Debug::assert code again, and _expression is then false again.

Hi Rudi,

I don't see anyway we can disable the code. I think the only way you can disable the code is by making sure the condition is true.

Could you please share your code as well? We can check if we can control the value in some way so that the assertion is always true.

[FormDataFieldEventHandler(formDataFieldStr(LedgerJournalTransDaily, LedgerJournalTrans, LedgerDimension), FormDataFieldEventType::Modified)] public static void LedgerDimension_OnModified(FormDataObject sender, FormDataFieldEventArgs e) { LedgerJournalTrans ledgerJournalTrans = sender.dataSource().cursor(); ledgerJournalTrans.TaxItemGroup = TaxItemGroupRuleSearch::getTaxItemGroup(ledgerJournalTrans.LedgerDimension,ledgerJournalTrans.TransDate); }

Sure I am just adding an event handler to the LedgerDimenson field on LedgerTransDaily.

But it hits the Debug::Assert code way before it hits my code.

Hi Rudi,

Maybe some setup is missing in that case. Which method in DimensionStorage is being called (which is causing the issue)?

It seems to be hitting DimensionStorage::find

I thought as much. There are 9 Debug::assert() calls here related to the ledger dimension passed and the hierarchy structure.

You could probably skip these calls as well by placing a breakpoint here (highlighted in red) and setting the next statement to the highlighted (in yellow) line.

Well it kind of works, but still it calls this method so meany times, so far I have skipped it 10 times, and it keeps coming back.

Hi Rudi,

The only other option would be to setup the account structures properly and make sure that the assert conditions are always true.

Hi Rudi,

Unfortunately, it's how debugger::break method works and you can't prevent hitting it with the attached debugger. Since Debug::assert is not hookable you can't modify it via CoC to pass always true value in "expression" parameter. Maybe you can consider other ways of debugging like using infolog, if assert method is too annoying.
