HANA Cloud Portal widget creation using SAPUI5 -

-

i'm trying create 2 widgets use <sap-context> feature hana cloud portal using sapui5 framework.

the problem cannot find tutorials/examples of using mvc model widget creation. every example have found till uses sapui5 inside <script> tag in html file if it's jquery or javascript.

is possible @ create widgets using mvc model @ all? if is, links examples/tutorials me alot.

nb:

as matter of fact, did try use mvc model, when try call function using following syntax:

sap.ui.getcore().byid('<view-name-here>').getcontroller().publish("<key-name-here>", "<value-here>");

i uncaught typeerror: cannot read property 'getcontroller' of undefined error. i'm not sure causes error - flaw in code or fact there no 'core' if don't build sapui5 application... (i'm still new sapui5 thing)

thank you.
