How to remove instances dynamically based on parameter from row objects

Level 2

Hi , guys

I'm using Adobe LiveCycle 10.4.0  ES2.0.​ ​I get confusing about using removeInstance(). I want to delete the row items based on parameter from data structure.  And my codes seems noneffective. My codes in table layout:ready* is :

var valFs;

var numrows = xfa.resolveNodes("SRFS_PL_FINSTMNT_XSD_REP_DATA.bdyMain.tblLineItems.rowLineItem[*]").length;

for (var x=0; x < numrows; x++)

{

      valFs = xfa.resolveNode("$record.LISTFINSTMNT.item[" + x  + "].FSTYPE").value;

      if (valFs == "AA")

    {

        SRFS_PL_FINSTMNT_XSD_REP_DATA.bdyMain.tblLineItems.rowLineItem.instanceManager.removeInstance(x);

    }

}

Actually, the result really delete some items, but it seems delete row items randomly. Can you please answer how to use removeInstance() if I want to delete row items depend on another parameter in table? Thanks.

Hi, you should go though your table backwards, so "for (var x=numrows -1; x >= 0; x--)" as deleting rows will change the number of rows but you have already calculated numrows.

Also, you should not do this in the layout:ready event as it will cause the event to fire again, see this reference https://helpx.adobe.com/pdf/aem-forms/6-3/scripting-basics.pdf#nameddest=G6.1668520
