How to run a processor / dialect after processing with standard Spring dialect is done?

[seb321]

Hi,

I try to implement a dialect. I want to process a <select> element with given attribute and its body. For this I use AbstractElementModelProcessor. However, model passed to doProcess is not (fully?) processed by the standard Spring dialect, i.e. it contains unprocessed th: attributes.

For the processor I need a value attribute of <option> element nested in <select>, but th:value is not processed yet.

I tried changing processor and dialect precedence value, but it does not seem to do anything useful for me.

How do I make the processor / dialect be called after standard dialect finishes its processing? The dialect can run in a second pass, I would not especially mind that.

I suppose that, in the example above, I could evaluate th:value myself, but it does not seem to be a solution, e.g. it will not work in case <option> elements are generated with <th:each>.

I use Spring Boot and spring-boot-starter-thymeleaf 2.3.7.RELEASE.

I would appreciate any help.
