[dart-misc] Polymer paper-dialog

[Mateusz Lewandowski]

Hi.
I am new in dart and polymer technology.
In last days i have a problem with using paper-dialog.
I have wanna use it as an element on typical dart page but idee hast told
me that it needed to be inside polymer element.
The goal is that i need to fire method from inside polymer element (now i
know how to firing methods from such polymer elements) which show me the
paper dialog with setted txt.
I have tried to use in my firing method the followin which had not effect:
1) this.open();
2)querySelector("somePaperDialogId").open();

How to open it using method?

Hi,

The open method should work like this, so likely something in the
surroundings of the paper-dialog element. Hard to tell without the full
code.

For me this have been a good resource
http://stackoverflow.com/tags/dart-polymer
Maybe a little old, but I think most still
valid https://github.com/dart-lang/polymer-dart-patterns
Actually there a specific dart web
group https://groups.google.com/a/dartlang.org/forum/?nomobile=true#!forum/web

I can not still resolve my problem
I am getting error:
Uncaught Unhandled exception:
The null object does not have a method 'open'.

NoSuchMethodError: method not found: 'open'
Receiver: null
here is my code
dart:

@CustomTag('messageinfo-element')
class MessageInfo extends PolymerElement {
@observable String message;

MessageInfo.created() : super.created();

void RunMessageInfo(String message)
{
this.message=message;

PaperDialog infos = this.querySelector("#dialog");
infos.open();
}
}

html:


<polymer-element name="messageinfo-element">
<template>
<paper-dialog id="dialog" heading="Dialog Title">
<p>{{message}}</p>
</paper-dialog>
</template>
</polymer-element>

It looks like querySelector is failing. Why the "this."? When I do
something similar, the code looks something like:

import 'dart:html' as html;

...

PaperDialog infos = html.querySelector("#dialog");
if (null != infos) {
infos.open();
} else {
// some kind of error handling
}

It is local dom of the
element. https://github.com/dart-lang/polymer-dart/wiki/local-dom

Another queryselector should be used
Polymer.dom(parent).querySelector(selector)
