D10.4 - Possible Bug when editing SQL

[Ian Branch 121]

Hi Team,

Having a SQL statement into the SQL of a Query.  When I open it I get the normal String List editor dialog, no issues.

If I then click the 'Code Editor...' button it opens the SQL into the Editor however I immediately get a "Access violation at address 207AF82F in module 'coreide270.bpl'. Read of address 00000000." error message.  No matter what I try to do in the editor the error message keeps popping up.

This is the error trace from the error message..

========================================================

I tried different Query components with the same result.

Can anybody confirm this issue or is it just me?

This doesn't happen with the same components in D10.3.3.

I see at least two 3rd party add-ons in your callstack. Does this also happen with a clean install?

[Uwe Raabe 1879]

I can reproduce it.

Hi Uwe,

With a clean D10.4 or with some 3rd party add ons?

Ian

[Ian Branch 121]

I just removed the two indicated add-ons and get the same result.

Not perfectly clean, but without those mentioned in your call stack.

Tks Uwe,

Feel free to add your own input and comments/vote to the RSP.

It is not even specific to a query, but probably happens with all TStrings properties. I can even reproduce it with a plain TMemo editing its Lines property.

[Ian Branch 121]

Confirmed.
