Because the JadeHTMLClass class buildFormAction method in earlier releases could not generate correct HTML in all circumstances, the method has now been replaced with the JadeHTMLClass class buildFormActionOnly method, which has the following signature.
buildFormActionOnly(): String;
If you call the new buildFormActionOnly method, you must change your HTML or JADE code to generate the form tag method attribute wherever you were using the superseded buildFormAction method with a non‑null value in the meth parameter (that is, a value of "get" or "post").
The return value of buildFormActionOnly method is the same as the return value of the superseded buildFormAction method when it was called with a parameter value of null.
