I have a workaround – I actually already had the keys in my own object, which I used to initialize app.
// Note: data can only be nested one-deep!
// As well, event functions cannot be nested!
const smartData = {
enrollmentNewSubmit: newEnrollmentSubmit,
enrollmentNew: {
courseID: ”,
loginName: ”,
studentID: ”
},
schoolNewSubmit: newSchoolSubmit,
schoolNew: {
name: ”,
shortName: ”,
description: ”,
address: ”,
city: ”,
stateCode: ”,
zipCode: ”,
province: ”,
country: ‘US’,
postalCode: ”,
codes: ”,
tags: ”,
notes: ”,
annex: ”
}
};
So, I can e.g.
for (const key of Object.keys(smartData.schoolNew)) {
console.log(<backtick>key: ${key} hasOwnProperty: ${boundAttrs.hasOwnProperty(key)} type: ${typeof boundAttrs[key]}<backtick>);
}

So, I can iterate through that way and get only my own added properties.
Please add some easy way to do this in the future, or let me know what I am missing if it already exists.

Well, ignoring functions won’t do it. Because the Proxy object has e.g. _canNotify which is boolean, propertyName string, notifyFn object.
I could filter these out explicitly (along with functions) after copying with Object.assign() but then I have to worry with each future release what has been added that I have to filter out.
What am I missing here? What is the use of of this if I cannot iterate my own properties that I added in app.data without pollution? I need to make a separate redundant list of my key names, it is a royal pain.

Ugh! This forum is IMPOSSIBLE! That code did not paste right. The forum did not like my backticks!
The line in my “for” is: (I substitute <backtick> for actual backtick below, because the forum doesn’t like backtick…)
console.log(<backtick>key: ${key} hasOwnProperty: ${boundAttrs.hasOwnProperty(key)}<backtick>);

To be more clear:
const boundAttrs = app.data.schoolNew;
console.info(‘boundAttrs’, boundAttrs);
console.info(‘boundAttrs.keys:’, Object.keys(boundAttrs));
for (const key of Object.keys(boundAttrs)) {
console.log(key: ${key} hasOwnProperty: ${boundAttrs.hasOwnProperty(key)});
}
This gives me the list of keys from above, and after adding check for own property, they are all own property.
So, how do I get JUST the bound variables from the Proxy object, WITHOUT pollution like “propertyName”, etc?
I guess I can filter out functions, and what is left will just be my properties? Isn’t there some function to do that for me? It would seem very common to want to iterate through bound variables, but there seems no convenient way to do it.

Sorry. That did not paste as I expected! (And there doesn’t seem to be any way to edit a post?)
boundAttrs.keys: (23) [“name”, “shortName”, “description”, “address”, “city”, “stateCode”, “zipCode”, “province”, “country”, “postalCode”, “codes”, “tags”, “notes”, “annex”, “hasOwnProperty”, “isPrototypeOf”, “propertyIsEnumerable”, “toString”, “valueOf”, “toLocaleString”, “_canNotify”, “notifyFn”, “propertyName”]

I think you missed the point. Sorry, I should not have mixed comments about the documentation with comments about Observables.
So, apparently, app.data items are Observables.
I want to be able to enumerate through e.g. app.data.enrollmentNew so that I can do something with all of the key/value pairs.
But I find that Observable objects are polluted with many additional properties that are NOT the properties that I defined in app.data.enrollmentNew. This makes it fairly useless for many purposes.
How can I iterate through ONLY the properties that I defined?
boundAttrs.keys:
<div class=”console-view-object-properties-section object-value-array source-code expanded”>
<div class=”tree-outline-disclosure tree-outline-disclosure-hide-overflow”>
1. 0: ”name”
2. 1: ”shortName”
3. 2: ”description”
4. 3: ”address”
5. 4: ”city”
6. 5: ”stateCode”
7. 6: ”zipCode”
8. 7: ”province”
9. 8: ”country”
10. 9: ”postalCode”
11. 10: ”codes”
12. 11: ”tags”
13. 12: ”notes”
14. 13: ”annex”
15. 14: ”hasOwnProperty”
16. 15: ”isPrototypeOf”
17. 16: ”propertyIsEnumerable”
18. 17: ”toString”
19. 19: ”toLocaleString”
20. 20: ”_canNotify”
21. 21: ”notifyFn”
</div>
</div>

Hi,
This is considered to be normal. Filtering requires additional html elements that the Grid should create. This will slow the things especially with several grids on the page. I suggest you to create the grids on demand when a tab is selected

Hello,
Thanks for writing.
Grid Aggregates/Summaries are not yet implemented. That is the reason why summary settings have no effect. When we implement them, we will add demos and docs and release notes.

Hi jtara,
We will consider your comments about our documentation and framework. About the listing of functions of objects – we document only built-in functions, not all inherited from HTMLElement.

FWIW, for now I revert to gathering input values using a little formToObj function that goes through and collects input, select, textarea values from the form…

I wrote in my previous post that it works only with defined height as shown in demos.

https://codepen.io/cetinsert/pen/eYOZqEg – I realized this works up to the CSS-defined height and fails again (9 rows in this link). Increase height in CSS and it works longer.
Thank you for your prompt responses.

I had already found a better workaround earlier for height auto, addNewRow!
1. Start with fixed height in CSS
2. Change height to auto in JS
Auto-height with add new row:
- broken – https://codepen.io/cetinsert/pen/mdbPYRJ
- working – https://codepen.io/cetinsert/pen/eYOZqEg (marked in CSS and JS panes as FIX1)
<hr />
What about the counter starting at 2?
Is that going to be addressed as well?
