I tried to modify sambapos application and my requirments 1) we are managing all setting in MANAGE tab and internally we are making many clicks in order to add any catagory and any table etc..
So i just want to keep all those functionalitys as a shortcut in POS module on menu tab i added one more Field like "+(plus) button" so if we click on that we need to allow user to add a catagory from here itself..
What i tried is i just kept a button as "+" and code behind given reference to already existing code other pages, But we unable to get it. it throwing NULL exception and i understand that the classes are not initalised but we are trying to use that and if we initalise those methods also we are gettiing issue while click operation performed as null exception
Please sugest me how to achieve this shortcut button operation in SambaPos
