- Update 341 JSON.stringify cannot serialize cyclic structures.

[joostvanhassel]

@ashapiro75: can you try opening Designer first and then (from within Designer) open the project? Does the error still occur? I noticed opening a (upgraded) project this way slightly differs (see: this post)

[anthonyterrell]

@joostvanhassel I had to open Designer first, as just clicking on the file itself never seemed to launch Designer fully.

@anthonyterrell: I tried taking those same exact steps, without updating the url prefix this time. I do get an error message, but it's this one:

Unable to load data using the supplied configuration.
Open in Browser: tree.json

Completely expected since it's trying to resolve tree.json at an unknown location. I don't get the JSON.stringify message.

[joostvanhassel]

@ashapiro75: maybe you can post the project as it is updated at your PC/mac now.

Just to be sure: have you closed all instances of Designer before opening a new Designer and opening the project?

Hi guys, we left off with me being unable to reproduce the issue with the provided project; I'm wondering if you are still seeing the issue with the updated beta build 355?

I see in in a message by clicking a a red explanation point by my store after starting up my project in Designer(Update 360).

I think that it relates to autoLoad. Start a new project and add the model and store below. Save it and close Designer and then reopen it. The red error explanation point will be beside the Store. Clicking gets the message.

If I remove autoLoad the message goes away.

The store works in my project.

I hope this helps.

@jjohnston: I'm not having the issue anymore, I'm fine (unrelated; it might be nice if this forum somehow could show if a question is answered in the threadlist, I guess this would help you guys browsing through all questions too)

@worthlutz:
1) is the error the same as in the threads title?
2) does the error occur only in Designer, or does your project not load any data while testing in a browser either?
3) could you call the exact url directly in your browser and post the output, so we can have a look to help you out?

[worthlutz]

The error only occurs in Designer and is the same as the thread title.

Could the problem be that the rootProperty, "map", object in the returned data has both the "extent" and "mapUrl" properties? Does the model have to "exactly" match the returned data object or can it pull out the required pieces if only some are needed in this case?

{"success":true,"parceldata":[],"map":{"extent":{"minx":2211826.2604003,"miny":648503.81250018,"maxx":2212980.7500002,"maxy":649623.93750018},"mapUrl":"\/tmp\/4f7d8e71_6a90_0.png"},"errorMessages":["NumRows = 1"],"ownerParcelList":[["SMITH, DAISY MAE STANCIL","14038026"]]}

w/ added linefeeds and spacing:

{
    "success":true,
    "parceldata":[],
    "map":{
         "extent":{"minx":2211826.2604003,"miny":648503.81250018,"maxx":2212980.7500002,"maxy":649623.93750018},
        "mapUrl":"\/tmp\/4f7d8e71_6a90_0.png"
    },
    "errorMessages":["NumRows = 1"],
    "ownerParcelList":  [["SMITH, DAISY MAE STANCIL","14038026"]]
}

I will be checking this shortly as well, I'm beginning development on the project today. Thanks for revisiting the thread.

[anthonyterrell]

Going through the same steps as before I receive the error still, running the latest build.

1. Download the project from this thread named nl3.zip
2. Open Sencha designer and choose the project file within the folder
3. Confirm I want to update the project
4. Click load data - receive error.
