Trigger a page edit to update page data
When you change the data def of a page, it doesn't seem to change the data that the page has when you read it by Web Services. This means that adding things into the new data def fields isn't easy, as the fields don't exist yet.
When you edit the page in Cascade and save it, the page then gets the new data def structure (even blank parts).
Is there a way to trigger this kind of editing by web services?

Hi,
There is no easy way to "trigger" the changes with web services without loosing the data. You have to store the data while you are changing the data definition. In Working with Data Blocks I talk about how to change data definitions associated with blocks. Everything said there is applicable to pages. The basic steps are:
StructuredDataobject out of the new data definition and copy all the data from the block/page to this object, and possibly assign new data to the new fieldsStructuredDataobject back to the block/pageThis should be quite straight-forward if you are just adding new fields, not removing existing fields or reorganizing them in groups.
For more information, see Lesson 7: Synching Data.

Hi Cascade Web Service Developers,
Will you be interested in a 3-part tutorial on Google Hangout? I am going to give an introduction to my library and show how to perform simple tasks like creating and editing assets. Details can be found on Online Tutorials.
If you are interested, send me an email. You can find my email address on Web Services: Encapsulation, Reusability, and Simplicity.
Wing
