Hello,
i would like to ask a question on extending sap.m.StandardListItem.
What i've done:
I have a single page app using a xml view. Within this view i declared the following:
xmlns:my=my
In the List:
<my:extendedStandardListItem title="{title}" newattr="{newattr}></my:extendedStandardListItem>
The binding of model data works fine:
I've created the JS file.
extendedStandardListItem.js containing the following:
jQuery.sap.declare("my.extendedStandardListItem);
sap.m.StandardListItem.extend(my.extendedStandardListItem", {
metadata{
library:"sap.m",
properties{
newattr :{ type:"string", group:"Misc", defaultValue:null}
},
renderer:function(oRm, oControl) {
//my.extendedStandardListItemRenderer.render(oRm,oControl) //This doesn't work -> Instead of calling the render Method of my.extendedStandardListItemRenderer it calls itself again and again until there is a callstack overflow
sap.m.StandardListItemRenderer.render(oRm, oControl); //This works & renders the standard Listitem correctly
}
The second JS file if created ist the following:
extendedStandardListItemRenderer.JS containing the following:
jQuery.sap.declare("my.extendedStandardListItemRenderer );
sap.m.StandardListItemRenderer.extend("my.extendedStandardListItemRenderer ", {
metadata:{
library:"sap.m"
}, renderer:function(oRm,oControl) { //<- This method doesnt get called
console.log("test rendering extendedStandardListItemRenderer );
}
Now the questions:
1) How do i have to call the render function of extendedStandardListItemRenderer?
2) How do i call the super() method in the render function of extendedStandardListItemRenderer?
Thank you for your your help. I'll reward points for any helpful and/or correct answers.
Have a nice day.
Regards,
Michael
