javascript - Titanium Android app crashes upon updating ScrollableView -
first of all: works intended in ios.
the issue believe java object generated titanium isn't getting parameter updates size of scrollable view.
error log:

relevant code:
//on scrolling of years view fill makes , model views function populatemake(e){ $.makescrollableview.scrolltoview(0); removeallchildren($.makescrollableview); //generating url var selectedyear = $.yearscrollableview.currentpage; //selected index var caryearviews = $.yearscrollableview.getviews(); //array of views var children = caryearviews[selectedyear].getchildren(); //children of selected year (aka label w/ year in it) var makeyear = children[0].gettext(); var url = "www.example.com"; var makeviews = []; var client = ti.network.createhttpclient({ onload : function(e){ var yearmakes = []; yearmakes = parsemakes(this.responsetext); //returns array of strings for(var = 0; < yearmakes.length; i++){ var yearlabel = ti.ui.createlabel({ title: "year", text: yearmakes[i] }); var view = ti.ui.createview({ backgroundcolor: 'blue' }); view.add(yearlabel); makeviews.push(view); } $.makescrollableview.setviews(makeviews); //<--- crashes here when scrolling $.yearscrollableview populatemodel(); }, onerror : function (e){ ti.api.error("http error populating makes"); } }); client.open("get", url); client.send(); } and:
//populate model when year/make changed function populatemodel(e){ $.modelscrollableview.scrolltoview(0); removeallchildren($.modelscrollableview); var selectedyear = $.yearscrollableview.currentpage; //selected index var caryearviews = $.yearscrollableview.getviews(); //array of views var childrenyear = caryearviews[selectedyear].getchildren(); //children of selected year (aka label w/ year in it) var caryear = childrenyear[0].gettext(); var url = "www.totallyafakewebsite.net"; ti.api.info(url); var modelviews = []; var client = ti.network.createhttpclient({ onload : function(e){ var carmodels = []; carmodels = parsemodels(this.responsetext); //array of strings for(var = 0; < carmodels.length; i++){ var modellabel = ti.ui.createlabel({ title: "model", text: carmodels[i] }); var view = ti.ui.createview({ backgroundcolor: 'blue' }); view.add(modellabel); modelviews.push(view); } $.modelscrollableview.setviews(modelviews); //<--- crash when scrolling $.makescrollableview //$.modelscrollableview.views = modelviews; //doesn't work either }, onerror : function (e){ ti.api.error("http error populating models: " + e.error); } }); client.open("get", url); client.send(); } these events triggered when corresponding scrollable view scrolled.
each scrollable view created in xml view.
i found own issue:
the reason why happening due own removeallchildren function not working. because titanium's function did not work had create own.
the inside of function looked this:
$.scrollableview.values = []; //an empty array instead used following code:
//remove old data $.makescrollableview $.makescrollableview.setcurrentpage(0); makeviews.length = 0; setting current index 0 , setting array length 0 resolved issue.
