ok i did something similar to deadlock technique to get the data
ordered.
But i still has a problem with the fill in.
What i mean is:
To avoid having nullpointer in the array i fill it with error msgs.
for (int i=0; i<arr.length; i++) {
for (int j=0; j<arr[i].length; j++) {
arr[i][j] = "error";
}
}
When RequestCallBack is called, inside i have the 2 well known
functions extractData that returns an JSONObject and the
updateResults.
Into update results i call another function , fill_data
private void updateResultsArea(JSONObject results) {
String value = getString(results.get("value"));
fill_data(name,value,counter);
increase();
}
Name is the url that is parsed every time RequestCallBack is called
( This is how i solved the matching part )
Value is the JsonValue and counter is a global variable , used as a
counter that is increased every time this function is called , in
order to save the data respectively.
But after the request messages are over, and i want to draw the
results in my panel using a draw_table() function , which has inside a
while loop. However, when it tries to print the data of the array , i
get the error msgs instead of the saved data.
This is what i have inside the basic constructor of my class
array_list.add("Name");
array_list.add("L_Name");
array_list.add("tel");
Iterator itr = array_list.iterator();
resultsArea.setSize("100%", "100%");
while(itr.hasNext())
{
// Here i send all json requests, taking back the results and trying
to save them in an array
SendJsonRequests(itr.next().toString());
}
// Here i want to use the data i saved in order to draw my
application
draw_table();
initWidget(resultsArea);
}
Now in the draw_table() function
By putting a Window.alert() msg , lets call it magic? dont know , but
the results are printed fine.
By comment window.alert() msg, all saved data is gone and error msgs
are printed!
private void draw_table()
{
int c2 = 0;
while( c2 < arr.length )
{
// Window.alert(arr[c2][0]+" <== ");
draw....
....
c2++;
}
Now may the prob is in how i use the global variables arr and counter?
i cant figure out why something like this is happening.
Any idea ?
Ty.
