CheckboxSelectionModel Doesn't Render After "Promote To Class"

[sae249833]

REQUIRED INFORMATION


Architect Build tested:

• Architect 2.1.0 Build: 678

Project Type:

• ExtJS 4.x

Description:

• 
  In a gridpanel, if I add a CheckboxSelectionModel and then use the "Promote to Class" option on that model the check boxes no longer render in the grid.
  
  I can clearly see that "selModel" is set (see below) but when I run the application there are no check boxes rendered in the grid (no checkbox column at all).
  
  

  selModel: {
    xtype: 'mycheckboxselectionmodel',
  }

  Messing around a bit I find I can make this work if I manually change the selModel config to the following. However, since I can't manually do it through Architect, the next time I publish it is overwritten. I need a solution to this otherwise I'll have ditch Architect.
  
  

  selModel: Ext.create('MyApp.view.MyCheckboxSelectionModel')

Steps to reproduce the problem:

• Create a grid.
• Add a CheckBoxSelectionModel
• Select the CheckBoxSelectionModel, right-click and select "Promote to Class"
• Run the application and display the grid.

The result that was expected:

• A grid with checkboxes.

The result that occurs instead:

• A grid without checkboxes.

HELPFUL INFORMATION
The reason for performing the "Promote to Class" is that I must add a renderer to the CheckboxSelectionModel, a very common need, and Architect provides no facility for doing this until you "Promote". At that point you can use an "override" to add the needed renderer.

Possible fix:

• Add renderer as a config option on the SelectionModel
• Add selModel and selType as config options on the GridPanel

Operating System:

• Linux 2.6.32-279

Thank you for the report! I have replicated this behavior, and opened a bug in our bug tracker. We appreciate you taking the time to file a detailed report with instructions to replicate the issue - it makes it much easier to help make Architect a better product.

I believe I have a solution for you that doesn't require a bug fix:

Select your Checkbox Selection Model in the inspector, and in the Config add a function (using the + button)

Call it 'renderer', and give it the same parameters that are typically passed to renderer. You can then use the code editor on that function and use your custom code. Can you give that a shot and let me know if it works for you?

Yes, this workaround was successful. Thank you for the assistance!
