I have a custom expression builder which I register using tag in web.config.
Is there a way to accomplish the same thing programmatically at startup?

Safe template engine (allow user to edit) in spring MVC?

I am wondering if there is a way to disable method invocations in thymeleaf? We would like to give our users the ability to edit the templates in our application. We plan to use thymeleaf, but we do not want users to be able to call methods or access static fields or methods.
I found an old post Disabling static context and method invocation in Thymeleaf It was not possible in 2018, I am wondering if it is still the case in 2022?
If this cannot be disabled in thymeleaf, then are there any safe template engines available in spring?
Thanks

Using an IoC container with Xamarin Forms 4.0 Shell to resolve page instances

I am currently attempting to migrate a current Xamarin Forms 2.0 application to make use of the new Xamarin Shell facilities (in particular the navigation). This existing application is based on a MVP pattern which means that in my Presenter layer i inject instances of my pages to allow the presenter to wire up events on the pages.
I am struggling at the moment in achieving this this Shell as from what I understand it is in control of creating instances of the pages and does not use the IoC I am currently using (which happens to be Unity).
Is there a way that I can configure the Shell to use my IoC container to resolve the page instances when it is creating them rather than creating them itself.
Any help on this would be appreciated.

Roo custom finders in java classes

I want to create a custom finder in my roo application. Most of the previous questions recommend creating the finders in the java classes, but I couldn't find the code to implement that and how to use it in my views or auto create the view.
Create your finders using finder add command.
Then customize the JSP page, the controller handler method and the finder method as needed.

Accessing http session attributes from Freemarker directive

Is that possible to access http session attributes from within Freemarker custom directive? If so, how?
That's up to the Web Application Framework if it puts such variables into the data-model (template context); FreeMarker doesn't do anything like that itself. Although, if the Web Application Framework is using freemarker.ext.servlet.FreemarkerServlet, it should be like Session.someAttributeName.

flexgrid custom data binding

Is it possible to bind a msflexgrid/mshflexgrid to a custom datasource in vb6?
Yes of course you can. This was one of the new features in VB6.
See Using the DataGrid Control with a Class Module which is for a DataGrid but the same thing works with the FlexGrids.
You can create data-aware Classes and UserControls, or you can create an OLEDB Simple provider.
