Hello Community, I’m working with the Excel Importer module, which depends on MxModelReflection. After adding both modules to my project, I consistently encounter errors such as: CE0462: Could not find widget ‘Combo box’ in the ‘widgets’ directoryCE0463: The definition of this widget has changed… After investigating, I noticed that these errors originate from internal pages and snippets inside the MxModelReflection module, where legacy Combo box widgets are still referenced. These UI artifacts are not used by Excel Importer functionality, but Mendix still validates them, which blocks the application from running even though the core reflection logic and microflows are intact. I tried: Updating all widgets Reinstalling both modules Avoiding any manual changes to the modules However, the errors persist as long as those UI pages/snippets exist. CE0462: Could not find widget 'Combo box' in the 'widgets' directory.- Snippet 'Member' (comboBox1, comboBox2, comboBox3)- Snippet 'DbSizeEstimate' (comboBox1)- Snippet 'Microflow' (comboBox1)- Snippet 'MxObjects' (comboBox1, comboBox2, comboBox3)- Snippet 'MxObjectReference' (comboBox1, comboBox2)- Snippet 'Token' (comboBox1, comboBox2, comboBox3, comboBox4, comboBox5, comboBox6)- Snippet 'MxObject' (comboBox1)- Snippet 'ValueType' (comboBox1)- Snippet 'MemberEnum' (comboBox1, comboBox2, comboBox3)- Page 'TestPattern_Edit'(All from module: MxModelReflection) CE0463: The definition of this widget has changed. Update this widget or update all widgets.- Data grid 2 'dataGrid21' (Snippet 'Microflow')- Data grid 2 'dataGrid21' (Snippet 'Tokens')- Data grid 2 'attributes', 'dataGrid21', 'dataGrid22' (Snippet 'MxObjects')- Data grid 2 'dataGrid21', 'dataGrid22' (Snippet 'MxObject')- Data grid 2 'dataGrid21' (Snippet 'SizeEstimate')- Data grid 2 'dataGrid21' (Snippet 'MemberEnum')(All from module: MxModelReflection) CE0456: Condition for visibility needs to be updated.- Property 'Condition for visibility' of layout grid row- Page 'Column_NewEdit'(Module: ExcelImporter) CE9804: Java dependency synchronization failed because one or more dependencies could not be found. -------------------------------------------------------------------------------------------------------------------------------- I am facing multiple consistency errors after adding MxModelReflection and Excel Importer modules. The errors are mainly CE0462 (Combo box widget not found) and CE0463 (widget definition changed), all originating from internal pages and snippets of MxModelReflection, plus one visibility error in ExcelImporter I need guidance on: What is the recommended and supported way to resolve these errors?

Just to add a small note in case it helps: as a best practice, it’s always a good idea to first check whether a module has any dependencies before importing it. As you can see in the screenshot, MxModelReflection has three dependencies, and adding those to the project before importing the module usually prevents issues like widget or DataGrid mismatches. You can follow the same approach for theExcel Importer module as well.
Also, I’d recommend doing this work on a new branch. When you try to remove and re-add modules on an existing branch, the userlib folder can sometimes end up with leftover .jar files, which may cause extra confusion and Java dependency errors. Starting from a clean branch generally makes the process much smoother.

Hi Chillem,
Import/ Download combox widget from Mendix Marketplace, and update all the widgets from error window, your widget related issues will be resolved.
