@Vortex-Estagiarios This is the 3rd or 4th thread you have created with little to no explanation or context about what you are doing or trying to achieve. Any more of these threads and we will have to ban you. You have not responded to any of my questions in previous threads.
If at every point you encounter a surprise or frustration, your response is to add it to the blacklist. Furthermore it is common to feel intimidate to journey down that bumpy "road less travel" and easily get burned by incomplete understanding.
Mango is awesome. It's easy to learn partially, and much harder to learn completely. Inspiring a strong appreciation for all that Mango is and can do will help in shorten the learning curve and eventually more projects are built on the Mango platform.
Certainly possible, I don't have time to get right into this right now but you could use the maDataSource service to check for the existence of the DS and create it if one matching the name attribute doesn't exist.
If this is remotely similar to making a new point using the maPoint service perhaps I can be of assistance here
I don’t ask you to give me an example , but I would like to know where I can learn myself ?
What is the best way to do myself a complete flex page with side bar and one or two windows ?
If I can pick up pieces of code an put it into the edit markup , it’s OK.
Just my five cent thought,
1.There is no best way to do a web page
2.Copy and paste pieces of code without understanding will make your learning disable.
3.The web technologies is a prerequisite, at least know the fundamentals,
3.1. HTML to define the content of web pages
3.2. CSS to specify the layout of web pages
4.The learning speed is your choice.Everything is up to you.If you are struggling, take a break, or search google for the material
5.Explore the example page provided by Mango. Examples are often easier to understand than explanations. Try it out yourself. In my opinion, this is one of the best playground for anyone who want to learn and understand Mango.
