I have created a managed package and installed it on a customers organization 6 months ago. I have recently made small updates to the package (addin a single visual force page and controller). As I understand, I cannot patch the customers existing package as the visualforce page is classed as a new component and therefore it reuires a new major version. My question is, when using the installation URL to install the new major version, will it seamlessly overwrite the exiting managed package, keeping all settings, profiles etc?
I have a requirement that I'd like to know if it is possible. I have visualforce page which will display the results of a SOQL query, however the SOQL query is dynamic and could be a query on Custom Objects or Standard Obejcts. I'm currently hard coding a SOQL query into the controller class whilst trying to figure out how it will work. I intend to display the results of the SOQL query in a pageBlockTable or dataTable in the Apex.
Is this possible in Salesforce, if so could anyone give me an example of how it would work both in Visualforce and Apex?
