How to pass context of oController into the formatter function?

[former_member256961]

Hello Friends,

I have a scenario where I have to pass the context of oController into the formatter function as inside the formatter function I want to access function belonging to oController. Below is code sample:

new sap.m.Input('payOut', {

  value: '',

  fomratter: oController.formatPayOutAmount 

})

Now inside fomatPayOutAmount() I want "this" to refer to oController.

Obvioulsy   [fomratter: oController.formatPayOutAmount , oController] is not working.

Regards,

Hi Murthy,

Have you tried this.

new sap.m.Input('payOut', {

  value: "",

  formatter: [oController.formatPayOutAmount  ,oController]

});

Thank you.

This works fine.

Hi Pruthvi,

formatter: jQuery.proxy(oController.formatHello,oController)  --> this is good. Thanks.

Hi Pruthvi,

Althoug the question is answered, could you please extend your answer to cover below point.

How to make sure formatter is called when the data is changed in the binded field. For now formatter is only called once during instantiation.

I tried to use model.refresh() and model.checkUpdate(), but model.refresh sets it to initail binded value and checkUpdate() is private method and if you see internally checkUpdate() also calls refresh()
