[ST 2.1.0-b2] two stores, same model: store items get overwritten (memory proxy)

[rainierwolfcastle]

REQUIRED INFORMATION


Ext version tested:

• Sencha Touch 2.1.0-beta3
• Sencha Touch 2.1.0-beta2
• Sencha Touch 2.0.1.1
• Sencha Touch 2.0.1 (works!)

Browser versions tested against:

• Chrome 21.0.1180.83 (Windows)

Description:

• two stores get created, based on the same model. items of the store which was created first, get partially overwritten
• The problem does NOT occur in ST 2.0.1

Steps to reproduce the problem:

• Create a complex model (see example below)
• create two JSON-Strings
• create two stores (with storeId) which load the JSON-Strings via a memory proxy
• When app is running, click "Get data" to create Store No. 1
• Click "Show Data" and check the console output
• Click "Get Data 2" to create Store No. 2
• Click "Show Data" again and check the console output

The result that was expected:

• Two stores
• Store 1 contains data of string 1
• Store 2 contains data of string 2

The result that occurs instead:

• When store No. 2 is created, some content of store No. 1 is overwritten
• If there are for example 4 items in store No. 1 and there are 3 items in store No. 2, the fourth item in store No. 1 remains the same.

Your test case isn't running for me. You don't need to have a controller and view and such... just console out things and run code.

see next Post

I changed the code above and tested it in ST 2.0.1, 2.0.1.1, 2.1.0-b2.
It only works in ST 2.0.1

[rainierwolfcastle]

still something missing?

[rainierwolfcastle]

Okay, again. Why is this still on INFOREQ?? Do you need any more information to reproduce this?

[rainierwolfcastle]

Even tested it with ST2.1.0 beta3.
Could someone please have a look?

[Jamie Avins]

I'll get this over to the tracker.

Hi,

The issue is that the associated items have an idProperty of SYM_NAME. The data that your loading into the second store loads associations with the exact same SYM_NAME but different values for other fields. When you load items with the same model and id (which you are in this case), the existing records are updated. This is not a bug in the framework.

Let me know if this explanation helps you.

Best,
Tommy
