How to display a single entity as Popup

Question

I am currently learning how to develop UI5 manually and without Templates. I am currently getting a model via an oData Request to a system and display the returning entity set as a table with ColumnListItems.

XML for Table view:

    <Table noDataText="Es stehen keine Aufträge in der Queue" id="table0" 
        items="{ImpMan>/QueryEntrySet}" 
        growingDirection="Downwards" 
        modeAnimationOn="false" 
        mode="SingleSelectMaster" 
        selectionChange="onSelectionChange">

       <!-- Here is column logic and ColumnListItem tags etc. -->
    </Table>

I have set the selectionChange-Listener to the method onSelectionChange.

Table view controller:

onSelectionChange: function (oEvent) {
    var oSelectedItem = oEvent.getSource().getSelectedItem();
    var context = oSelectedItem.getBindingContext("ImpMan");
    var entity = context.oModel.getProperty(context.sPath);
    alert(entity.id);
}

I am able to get the whole clicked entity and the context.sPath which shows me /EntitySet('ID'). So I know exactly which Entity was clicked on. Now i want to show all details to this entity and therefore have to pass it to the popup. I already created a fragment with an objectlistitem:

<core:FragmentDefinition xmlns:core="sap.ui.core">
<Dialog xmlns:core="sap.ui.core" xmlns:mvc="sap.ui.core.mvc" xmlns:html="http://www.w3.org/1999/xhtml" xmlns:cd="http://schemas.sap.com/sapui5/extension/sap.ui.core.CustomData/1" xmlns:action="http://schemas.sap.com/sapui5/extension/sap.ui.core.CustomData/1" xmlns="sap.m" id="transportDialog" title="Auftrag">
    <ObjectListItem type="Active" number="{path:'ImpMan>PIMPDATE',formatter:'.formatter.getDate'}" numberUnit="Geplanter Import" intro="Gruppe: {ImpMan>GROUP_ID}" id="item0" title="{ImpMan>TRKORR}" icon="sap-icon://product" highlight="{path:'ImpMan>CRIT',formatter:'.formatter.critState'}">
        <attributes>
            <ObjectAttribute text="{ImpMan>ID}" id="id_att"/>
            <ObjectAttribute text="{ImpMan>ID_TEXT}" id="description" title="Beschreibung"/>
            <ObjectAttribute text="{ImpMan>LAST_EDIT}" id="last_change" title="Letzte Änderung"/>
            <ObjectAttribute text="{ImpMan>CHANGEDBY}" id="editor" title="Verantwortlicher"/>
        </attributes>
    </ObjectListItem>
</Dialog>

I also know how to define the fragment as Dialog and open it. But I am unable to bind the entity I extracted from the clicked table to the new Dialog and display its values..

Can anyone help me with this? How is this supposed to work?

First of all it's not recomended access internal variable direct, so you have to change.

 var entity = context.oModel.getProperty(context.sPath);

to

 var entity = context.getModel().getProperty(context.getPath());

Now about your question, when you open a Dialog you will have a variable with you dialog, you can BindElement on that like:

... 
var oDialog = sap.ui.xmlfragment(
                        "<fragment_path>", this);
...
oDialog.bindElement(context.oModel.getProperty(context.getPath()));
oDialog.open();
...
