TreePanel and TreeStore problems when opening 1.1.2 project with 1.2.2 Build 48

ryanrca -

THanks much for the project file and sample.

Can you please repost the json file in plain text format? It's currently whatever your browser interpreted.

oops, attached here is the JSON in the raw...

I'd also like to emphatically state that I didn't create that solution and I'm not responsible for any best practice violations that might be found therein...

I've found a (the?) source of our Designer "TypeError: 'undefined' is not an object" crashes. We use grid templatecolumns similar to the one below throughout our projects:

tpl: '<span class="{[(values.SafetyManagerStatusName.toLowerCase() != "closed") ? "negative" : "positive"]}">{SafetyManagerStatusName}</span>'

It seems that Designer is trying to interpret the .toLowerCase() call when the class is rendered in the design view. Since we create and bind our stores in the code behinds (as opposed to stores created in the Designer) the data value would appear to be null at design time, causing the error.

I'd call this a Designer bug, but regardless, is there a better way to handle the template scenario I've given?

FIXED: I came up with a fix for this particular issue. Converting the values.ColumnName value to a string first and then converting toLowerCase results in a text string of "undefined" rather than chucking an undefined reference error. See below:


tpl: '<span class="{[(String(values.SafetyManagerStatusName).toLowerCase() != "closed") ? "negative" : "positive"]}">{SafetyManagerStatusName}</span>'

ryanrca,

I am able to open your project fine in Ext Designer 1.2.2. Since we are not fixing any issues in 1.1 could you upgrade to 1.2.2.

Thanks
