I had this happen today in an example I got from a JIRA bug[1] as the test. In that example (see the paste.apache.org link in the bug) you'll see there is only the 1 mxml file. I could not get this example to work:
The myCombo.dataProvider setter needed to get to the combo box model which was not being created since there was no bead defined for it in the default.css media query for JS. When I followed the code down, failure of fetching the model made the Language.as fail because one of the operands, which was supposed to be the model, was null. Its probably not your model, but it must be something else that's not initialized. Also, maybe try applicationComplete as the event? I am off on a break for the rest of the week (US holiday this week), but I'll check email periodically. Good luck! —peter [1] https://issues.apache.org/jira/browse/FLEX-35169 On 11/21/16, 6:19 PM, "carlos.rov...@gmail.com on behalf of Carlos Rovira" <carlos.rov...@gmail.com on behalf of carlos.rov...@codeoscopic.com> wrote: >The example is failing in EventDispatcher.js here: > >event is "initComplete" > > >/** > * @export > * @override > */ >org.apache.flex.events.EventDispatcher.prototype.dispatchEvent = >function(event) { > try { > if (event) { > if (typeof(event) == "string") { > event = new org.apache.flex.events.Event( >org.apache.flex.utils.Language.as(event, String)); > event.target = this._target; > } else if ("target" in event) { > event.target = this._target; > } > } > else > return false; > return >org.apache.flex.events.EventDispatcher.superClass_.dispatchEvent.apply(thi >s, >[ event] ); > } catch (e) { > if (e.name != "stopImmediatePropagation") > throw e; <--------- > } > return false; >}; > >2016-11-21 23:15 GMT+01:00 Carlos Rovira <carlos.rov...@codeoscopic.com>: > >> Hi Peter, >> just tested DataBindingExample and is working. >> In my example I use >> >> <additionalCompilerOptions>-compiler.exclude-defaults-css- >> files=HTML-0.8.0-SNAPSHOT.swc:defaults.css</additionalCompilerOptions> >> >> In order to get rid of whatever CSS rules that could be inherit from >> HTML.swc >> >> So I put in my MDL lib css this: >> >> @namespace "library://ns.apache.org/flexjs/mdl"; >> >> List >> { >> IBeadModel: ClassReference("org.apache.flex.html.beads.models. >> ArraySelectionModel"); >> IBeadView: ClassReference("org.apache.flex.html.beads.ListView"); >> IBeadController: ClassReference("org.apache. >> flex.html.beads.controllers.ListSingleSelectionMouseController"); >> IBeadLayout: ClassReference("org.apache.flex.html.beads.layouts. >> VerticalLayout"); >> IContentView: ClassReference("org.apache.flex.html.supportClasses. >> DataGroup"); >> IDataProviderItemRendererMapper: ClassReference("org.apache. >> flex.html.beads.DataItemRendererFactoryForArrayData"); >> IItemRendererClassFactory: ClassReference("org.apache.flex.core. >> ItemRendererClassFactory"); >> IItemRenderer: ClassReference("org.apache.flex.html.supportClasses. >> StringItemRenderer"); >> IViewport: ClassReference("org.apache.flex.html.supportClasses. >> ScrollingViewport"); >> IViewportModel: ClassReference("org.apache.flex.html.beads.models. >> ViewportModel"); >> border-style: solid; >> border-color: #222222; >> } >> >> To ensure I have a model (and other beads) >> >> >> >> 2016-11-21 22:57 GMT+01:00 Peter Ent <p...@adobe.com>: >> >>> I had an issue today with ComboBox and its model not being present on >>>the >>> JS side; it was building SWF only.
