iron-selector failed to update its selection when data updating

[hedcet]

iron-selector failed to update its selection when receive new mail https://github.com/ebidel/polymer-gmail/blob/master/index.html#L152

i have the same issue in another open source repo https://github.com/HedCET/TorrentAlert/blob/master/.polymer/linto/project-list.html#L153

@ebidel could u possible to suggest any solution ?

[ebidel]

Can you give me more details? What do see? What do you expect to happen. A screenshot would also be helpful.

[hedcet]

selected property of iron-seletor is propagated in to mail-thread element to show selectable-icon in it as check

to recreate this issue - first select an mail-thread then the iron-selector selected-items="{{selectedThreads}}" contain an array of mail-thread, after that just add an new item at top of this array items="[[threads]]" then the iron-selector not update its selection to 1 mail-thread down

[ebidel]

after that just add an new item at top of this array

How are you doing that?

[hedcet]

this is the same situation when new mail come at the time selection is enabled

document.querySelector('#t');
<template id=​"t" is=​"dom-bind">​…​</template>​
var template = document.querySelector('#t');
undefined
template.unshift("threads", document.querySelector('#t').threads[0])
101

@ebidel in my example i already specified the attribute-for-selection but still iron-selector failed to update its selection

[ebidel]

Yea, I see what you mean. The proper fix is probably upstream in iron-selector.

[hedcet]

@ebidel PolymerElements/iron-selector#82 this was filed in NOV

[hedcet]

@ebidel any updates ?

[ebidel]

Please ping the upstream bug. There's not much I can do until that's fixed.

[ebidel]

The whole app is read only, meaning it doesn't actually change your Gmail
data.
