copied!<p>Here is the solution that I use for now:</p> <p>First some facts:</p> <ol> <li>I will have to cover multiple R/W operations (in particular after every field that changed and looses focus)</li> <li>I always get all data back on each request</li> <li>I have to cover a huge amount of data (field data, store data, labels and configurations)</li> <li>I have to optimize this mess to be performance critical</li> <li>There is no way to store anything in a server side session</li> <li>The forms are nested wildly one into another and may also be split up or exists twice</li> </ol> <p>Here's what I do for now:</p> <p>I drop all associations and decided to go with just one Model extended from a Model with a modified <code>getData</code> method which supports a custom root property like <code>someSubForm</code> (see my example code in the question). The fields are configured as auto so so changes to the reader or writer are needed. Maybe not rock solid but it works.</p> <p>Next big problem are the forms. The form will always try to set each field even if it is in another form. In addition I need to set quite a lot standalone labels. So the default form cannot be used, should I extend? But how and where should I start? After a long look at the source it seems to me that I cannot extend so I decided to create a totally custom form class along with a custom mixin class and custom form.basic class. Why? Because I need to form to look only at the field directly placed into this form, be able to set labels and hand the model instance to any nested form.</p> <p>With that I can now register my own monitor instances with a custom selector each. Oh,I forgot the first thing about my new form; it is bound to a entity by a property which contains the name (like <code>someSubForm</code>). </p> <p>This is used when</p> <ol> <li>A Item is added to the form <ul> <li>any field get a formId </li> <li>any label get a formId (not the labels that are bound to a form)</li> <li>any form get a parentFormId and the instance</li> </ul></li> <li>The Monitor selectors are setted</li> <li>A model is load into a form</li> <li>Data is fetched from a model</li> </ol> <p>Second is that there are now 3 monitor instances</p> <ol> <li>Collect all fields by using the new selector which also looks for the Entity. By that any subform fields get ignored, cause they have their own entity</li> <li>All the same for labels</li> <li>Collect all forms</li> </ol> <p>The third is the modified <code>loadRecord</code> method which uses the new <code>getData()</code> method of the model and sets the specific data to fields, labels and the whole model to any form.</p> <p>All in all I have a performance boost of 800% with that. </p>
