dojox.grid - Upgrade from Dojo 1.4 to 1.8 -


I am working on Dojo's migration from 1.4 to 1.8. I have a project in which there are some jeep pages in which the dojo is written and it takes the path of dojo from an XML file. I have changed the path to dojo 1.8 library from the dojo 1.4 library, but after doing this, the references of dojo widgets are throwing an error

for example dijit.byId ("idofwidget")

Error: dijit.byId ("idofwidget") Whether an object is empty or not.

Please guide to solve this problem and it will be better if steps are taken to upgrade the basics.

Thanks in advance

If you are actually going to upgrade to Dojo 1.8 , You will have to type your code again in the AMD, for example: 

  // Load the required modules (["dijit / registry ", Dojo / Ready", "Dojo / Parser"], Function (Registry, Ready) {Wait until the dome ends + Widgets are generated on the page (function () {// Widget instance registry. Recovering D ( "idofwidget");});});   
 One important thing to know is that you do not upgrade dojo, then you migrate it (at least when using pre-and post-17). Usually it involves that you can not simply change the dojo library, but you have to migrate your code too.  
 For example, there are some articles about the migration of pre-1.7 to 1.7.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
