creating store and model dynamically

[anaP]

Hi all,
I am trying to create model and store dynamically and also a view using json.
below is the code to create store and model dynamically.

function modelFactory(name, fields) {return Ext.define(name, {
extend: 'Ext.data.Model',
config:{
fields: fields
} });
}


function storeFactory(storeName,modelName){
return Ext.define(storeName, {
extend: 'Ext.data.Store',
requires:[modelName],
config:{
model:modelName,
}
});


then I create a view from json document


modelFactory(panel.model,panel.modelFields);
storeFactory(mytaskGrid.store,panel.model);
tabPanel=viewport.insert(1,mytaskGrid);
tabPanel.setStore(tabPanelStore);



but it gives error as Uncaught TypeError: Cannot read property 'store' of undefined
Where am I going wrong?
Do I have to create instances of model and store?
If yes then how?

Thanks in advance.

Have you try to use string instead of "object" ?




modelFactory('panel.model', 'panel.modelFields'); // <- use string

storeFactory('mytaskGrid.store', 'panel.model'); // <- use string



Maybe this will work better since Ext.define uses a String as first parameter, and so !

panel.model is a string value and panel.modelfields contains array of fields to create model.
How can I pass them as String?

modelFactory(panel.model,panel.modelFields);
storeFactory(mytaskGrid.store,panel.model);
tabPanel=viewport.insert(1,mytaskGrid);
tabPanel.setStore(tabPanelStore);

What is mytaskGrid? What is mytaskGrid.store?
What is tabPanelStore? What is tabPanel.setStore()?
Do you know where is the point that the error happens?
