Model Editor failed to load. - 'FontStyle' property specified was not found.

[pavlovboris]

Hello,

After updating to 23.1.601.3, Devexpress model editor won't start on any project with the following exception : System.Reflection.CustomAttributeFormatException: 'FontStyle' property specified was not found. --->

The XpandModelEditor seems to work as expected.

Thank you for your great work and support!

I would search all files in all dirs for this property FontStyle maybe it can give us a clue what's going on, if not I require a sample reproducing the case.

[apobekiaris]

a tip from the XAF team, it maybe a version conflict e.g. if u use different a version TypeA!=TypeA

[apobekiaris]

if u can repro it and does not involve eXpandFramework, you need to ask the DX support

[pavlovboris]

Thanks for the hints! Found out the following: if I remove all attributes that have [Appearance ... FontStyle](Excel importer as well(ExcelColumnMap)) then the model editor loads correctly. As far as your suggestion, I will try to repro and will contact DX if find more, but the exception occurs only when 23.1.601.3/23.1.601.2 is installed, it does not appear with 23.1.601.1 That's why I thought that its something with exPand.

it still can be a version conflict, but in any case as I can not repro it nor my tests or my apps fail, I can only help u If I have a repro sample

[pavlovboris]

Dont want to lose our time anymore on this, I can live without the appearance attribute FontStyle in Code and without excelimporter module. Maybe I will try to repro later only with excelimporter module, Can close for now.

Thank you and BR
