bind bound oData function to UI5 control

[akuller]

Hi all,

i want to bind a bound function to an control as described here: https://sapui5.hana.ondemand.com/sdk/#/topic/b54f7895b7594c61a83fa7257fa9d13f

we have great examples for unbound functions:

<VBox id="getAvailableItems" binding="{path : '/GetAvailableItems(...)', parameters : {$select : ['ProductName', 'ProductId']}}">
    <List id="xyz" items="{value}">
        <items>
            <ObjectListItem title="{ProductName}" />
        </items>
    </List>
</VBox>

but for bound functions only the js part is referenced:

var ...
    oSalesOrderContext = oTable.getSelectedItem().getBindingContext(),
    oAction = oModel.bindContext("name.space.InvoiceCreated(...)", oSalesOrderContext);
 
oAction.invoke()...

I've been trying to do this directly with a binding in the xml view for some time now, but it doesn't work. Has anyone got it working?

did you check this?

the binding path in your xml should be something like this(I haven't tried.),

var oContext = oModel.createBindingContext("/EMPLOYEES('1')/##com.sap.gateway.default.iwbep.tea_busi.v0001.AcSetIsOccupied");

Hi @junwu i know this chapter, i have also linked it above. my question, however, is whether i can bind a bound function directly in the xml view. As shown in the example for an unbound operation, without js code. Unfortunately it's not working for me.

[junwu]

show me what you did

Hi @junwu

eg:

<VBox id="getAvailableItems" binding="{path : '/getHierarchy(...)', parameters : {$select : ['ID', 'Name']}}">
    <List id="xyz" items="{value}">
        <items>
            <ObjectListItem title="{Name}" />
        </items>
    </List>
</VBox>

add a namespace to the path, remove all parameters, bind only the path, ...

I really only want to do this for a bound function without js code

[junwu]

then, did you read what I wrote regarding the path?

Hi @junwu

Yes, it works, but the # is wrong. But that's not my question. I already have a context and want to access the bound function from it.
I come from the list report to the object page, where I have my own fragment in which I define my table. Here it should derive the context independently without js coding from me.
