Error Opening Project - TypeError: 'undefined' is not an object

[timmcintyre]

After saving my project this morning, I just tried to restart Designer and I am now getting a TypeError: 'undefined' is not an object error. It opens up my project however I no longer have any controllers or views visible. The only thing I can see is my stores.

Any idea how to track down whats gone wrong ?

So Ive narrowed it down to a linked resource I just added. If I remove this from the metadata code, I can open my project, however I now need to add back in my linked resource. Once I close down Designer it wont open again until I manually fix this code .. any ideas why this is happening ?

,        {
            "id": "ExtBox1-ext-gen73583",
            "type": "linkedinstance",
            "reference": {
                "name": "items",
                "type": "array"
            },
            "codeClass": null,
            "userConfig": {
                "layout|region": "north",
                "id": "ar_gridpanel"
            },
            "customConfigs": [],
            "iconCls": "icon-linkedinstance",
            "expanded": true,
            "masterInstanceId": "ExtBox1-ext-gen73537"
        }

Any chance you could share an archive of your project with us on the architect team?

The broken one that is You can send it to designer.feedback at sencha.com and link this thread as a reference.

I'm able to reproduce so we'll get to the bottom of it. Gimme a few

Ok so solution time!

First I can't answer how you project got into this state though we are going to look a little bit deeper into the upgrade process to be sure we didn't cause this.

The issue is your BookingAddResources window had a linked instance that was no longer valid ... e.g. the id it had didn't exist in your project (ucmpGridBar) see line 1785 of metadata/view/BookAddResource.js

"masterInstanceId": "ucmpGridBar" --Error

replace this line with:
"masterInstanceId": "ExtBox1-ext-gen67263"

This id is the actual id of your GridBar component

I will tell you that in the past we didn't load up the components with dependencies in mind we assumed all would be available by the time you needed it. However this wasn't true in some cases so it now loads in order wrt dependencies and thus this new code that you are now breaking on. It's possible this was broken before and you just didn't know about it.

Lemme know if this fixes the issue.

Hi Phil,

Yep that did it, not sure how it ended up that way in the first place though. Might be worth expanding the error messaging in the designer to tell you where any errors like that may stem from.

Either way .. thanks for sorting out the issue . .Ive opened up the project & re-saved it with no issues

Cheers
