  1. POFlex AdvancedDataGrid listItems strange behaviour
    text
    copied!<p>I have the following XML, that is the dataprovider (as a Hierarchicaldata) of an Advanced DataGrid:</p> <pre><code>public var reqData:XML = &lt;root&gt; &lt;Requirement ID="REQ-GEN-0.1" title="exigence gen 1" description="blabla 01" testable="true"/&gt; &lt;RequirementSet ID="GUI REQ"&gt; &lt;Requirement ID="REQ-GUI-1.1" title="exigence ihm 1" description="blabla 11" testable="true"/&gt; &lt;Requirement ID="REQ-GUI-1.2" title="exigence ihm 2" description="blabla 12" testable="false"/&gt; &lt;/RequirementSet&gt; &lt;RequirementSet ID="PERF REQ"&gt; &lt;Requirement ID="REQ-PERF-2.1" title="exigence perf 1" description="blabla 21" testable="true"/&gt; &lt;Requirement ID="REQ-PERF-2.2" title="exigence perf 2" description="blabla 22" testable="false"/&gt; &lt;Requirement ID="REQ-PERF-2.3" title="exigence perf 3" description="blabla 23" testable="true"/&gt; &lt;Requirement ID="REQ-PERF-2.4" title="exigence perf 4" description="blabla 24" testable="false"/&gt; &lt;Requirement ID="REQ-PERF-2.5" title="exigence perf 5" description="blabla 25" testable="false"/&gt; &lt;Requirement ID="REQ-PERF-2.6" title="exigence perf 6" description="blabla 26" testable="false"/&gt; &lt;/RequirementSet&gt; &lt;RequirementSet ID="BUS REQ"&gt; &lt;RequirementSet ID="BUS 1 REQ"&gt; &lt;Requirement ID="REQ-BUS-3.1.1" title="exigence bus 1" description="blabla 311" testable="false"/&gt; &lt;Requirement ID="REQ-BUS-3.1.2" title="exigence bus 2" description="blabla 312" testable="true"/&gt; &lt;/RequirementSet&gt; &lt;RequirementSet ID="BUS 2 REQ"&gt; &lt;Requirement ID="REQ-BUS-3.2.1" title="exigence bus3" description="blabla 321" testable="true"/&gt; &lt;/RequirementSet&gt; &lt;RequirementSet ID="BUS 3 REQ"/&gt; &lt;RequirementSet ID="BUS 4 REQ"&gt; &lt;Requirement ID="REQ-BUS-3.4.1" title="exigence bus4" description="blabla 341" testable="false"/&gt; &lt;/RequirementSet&gt; &lt;RequirementSet ID="BUS 5 REQ"/&gt; &lt;RequirementSet ID="BUS 6 REQ"/&gt; &lt;/RequirementSet&gt; &lt;/root&gt;; </code></pre> <p>And here is the AdvancedDataGrid part:</p> <pre><code>&lt;mx:AdvancedDataGrid id="reqADGtest" displayItemsExpanded="true" width="95%" height="75%" horizontalCenter="0" contentBackgroundAlpha="0.0" chromeColor="0xdbeaff" openDuration="500" dragEnabled="true" dropEnabled="true" dragMoveEnabled="true" editable="true" variableRowHeight="true" horizontalScrollPolicy="auto"&gt; &lt;mx:columns&gt; &lt;mx:AdvancedDataGridColumn dataField="@ID" headerText="ID"/&gt; &lt;mx:AdvancedDataGridColumn dataField="@title" headerText="Titre"/&gt; &lt;mx:AdvancedDataGridColumn dataField="@testable" headerText="Testable"/&gt; &lt;mx:AdvancedDataGridColumn dataField="@description" headerText="Description" editorUsesEnterKey="true" wordWrap="true"/&gt; &lt;/mx:columns&gt; &lt;/mx:AdvancedDataGrid&gt; </code></pre> <p>The problem is that when I look at the listItems' length of the AdvancedDataGrid, it is 19 at the creation, and then 16 that is totally wrong (22 items). I want to access to some items and I can't which is really annoying. Is it a bug or something?</p> <p><strong>NOTE:</strong></p> <p>To access items by rowIndex and columnIndex I'm doing the following:</p> <pre><code>var advancedDataGridListData:AdvancedDataGridListData = IDropInListItemRenderer(listItems[event.rowIndex][event.columnIndex]).listData as AdvancedDataGridListData; IHierarchicalCollectionView(dataProvider).getChildren( advancedDataGridListData.item) </code></pre> <p><strong>EDITED 23/02/2012</strong></p> <p>I tested your solution with event.item but unfortunatly this item was always null and I didn't understand why. So I looked deeper into the source code of AdvancedDataGridBaseEx and I found that this is a part of the Adobe source code):</p> <pre><code>// send event to create the new one var advancedDataGridEvent:AdvancedDataGridEvent = new AdvancedDataGridEvent(AdvancedDataGridEvent.ITEM_EDIT_BEGINNING, false, true); // ITEM_EDIT events are cancelable advancedDataGridEvent.columnIndex = columnIndex; advancedDataGridEvent.dataField = _columns[columnIndex].dataField; advancedDataGridEvent.rowIndex = rowIndex; dispatchEvent(advancedDataGridEvent); </code></pre> <p>You can see that the event.item is never filled!!!! Thanks Adobe... I will try your other solution then I give you feedback.</p> <p><strong>LAST EDIT</strong></p> <p>I solved my problem by using in my custom datagrid:</p> <pre><code>var xmlNode:XML = this.selectedItem as XML; </code></pre>
