Dojox/mvc/sync triggers widget's custom setter second time












0














I'm using sync function to set up a two-way binding between Stateful object and custom widget.



When I'm using custom setters in the widget they are tiggered twice for a change: fisrt one - because I call this.set('property','value') internally in my widget and second - when update comes from the syncronized object.



In log it looks like:



dojo.Stateful:columnsSettingsPreset is being copied from: Component:activePreset (Value: [object Object] from undefined)

sync.js:126 Component:columnsSettingsPreset is being copied from: dojo.Stateful:columnsSettingsPreset (Value: [object Object] from undefined)

sync.js:126 Component:activePreset is being copied from: dojo.Stateful:columnsSettingsPreset (Value: [object Object] from undefined)


Custom setter looks like this:



_setActivePresetAttr(preset) {

    console.log('I am setting active preset:', preset)

    this._set('activePreset', preset) //If not to call this, watchers won't be notified

}


Log will be printed twice if I call this.set('activePreset', preset) somewhere in widget.



Is there any way to prevent this behavior?

          count number of partitions of a set with n elements into k subsets

          up vote 6 down vote favorite 1 This program is for count number of partitions of a set with n elements into k subsets I am confusing here return k*countP(n-1, k) + countP(n-1, k-1); can some one explain what is happening here? why we are multiplying with k? NOTE->I know this is not the best way to calculate number of partitions that would be DP // A C++ program to count number of partitions // of a set with n elements into k subsets #include<iostream> using namespace std; // Returns count of different partitions of n // elements in k subsets int countP(int n, int k) { // Base cases if (n == 0 || k == 0 || k > n) return 0; if (k == 1 || k == n) return 1; // S(n+1, k) = k*S(n, k) + S(n, k-1) return k*countP(n-1, k) + countP(n-1, k-1); } // Driver program int ma

          A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

          Image
          0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that? This is a MWE: documentclass{book} usepackage[nottoc,notlot,notlof]{tocbibind} usepackage{hyperref} begin{document} frontmatter tableofcontents mainmatter part{First} chapter{
