Hello,
Thanks for discussing this issue. Yes, I would like to run a angular
paragraph from another angular paragraph. Now, I have explored a bit about
angularWatch and looked very promising. I have more or less achieved what I
wanted to. But still it is not 100%.
I have this piece of code in one of my spark paragraph. This is para 6.
.....
z.angularBind("routeSelected", 0);
z.angularUnwatch("routeSelected");
z.angularWatch("routeSelected", (before, after) => {
// trigger re-rendering of cytoscape graphs
z.run(8) // re-render cytoscape density graph
}
)
.....
......
The routeSelected variable will be modified by para 7 which is angular
based using the below code
...
scope.routeSelected = scope.routeSelected + 1
....
Since the variable routeSelected is under watch, I expected para 8 will
run. But, the para 8 did not run automatically. To my surprise, it is run
when I click anywhere in the para 8, 7 6. It is very strange. Any clue
about this behavior?
regards
Bala
