Issue: Fuse Preview will crash when updating an Observable on a TextInput element that has the IsPassword property set to True.

The below code recreats the outlined issue:

<Javascript>
var Observable = require('FuseJS/Observable');

var iAmValue = Observable("");

var valueChanged = function (args) {
    if(args.value.length > 4) {
        iAmValue.value = args.value.substring(0, 4)
    }
}
</Javascript>

<TextInput ux:Name="iAmInput" ValueChanged="{valueChanged}" Value="{iAmValue}" IsPassword="True" />

However it will work if the IsPassword property is set to False, e.g.:

<Javascript>
var Observable = require('FuseJS/Observable');

var iAmValue = Observable("");

var valueChanged = function (args) {
    if(args.value.length > 4) {
        iAmValue.value = args.value.substring(0, 4)
    }
}
</Javascript>
<TextInput ux:Name="iAmInput" ValueChanged="{valueChanged}" Value="{iAmValue}" IsPassword="False" />

Hi, I’m unable to reproduce this issue. Which version of Fuse do you have? You can find it in the tray icon or by doing fuse --version. Are you on Windows or OS X?

Fuse version 0.9.7 (build 5544) on Windows 10 Appologies for not supplying that on the initial post.
